SpringCloud微服务实战——搭建企业级开发框架(二十三):Gateway+OAuth2+JWT实现微服务统一认证授权

开发技术 开发技术 3小时前 2次浏览

  OAuth2是一个关于授权的开放标准,核心思路是通过各类认证手段(具体什么手段OAuth2不关心)认证用户身份,并颁发token(令牌),使得第三方应用可以使用该token(令牌)在限定时间、限定范围访问指定资源
  OAuth2中使用token验证用户登录合法性,但token最大的问题是不携带用户信息,资源服务器无法在本地进行验证,每次对于资源的访问,资源服务器都需要向认证服务器发起请求,一是验证token的有效性,二是获取token对应的用户信息。如果有大量的此类请求,无疑处理效率是很低,且认证服务器会变成一个中心节点,这在分布式架构下很影响性能。如果认证服务器颁发的是jwt格式的token,那么资源服务器就可以直接自己验证token的有效性并绑定用户,这无疑大大提升了处理效率且减少了单点隐患。
  SpringCloud认证授权解决思路:认证服务负责认证,网关负责校验认证和鉴权,其他API服务负责处理自己的业务逻辑。安全相关的逻辑只存在于认证服务和网关服务中,其他服务只是单纯地提供服务而没有任何安全相关逻辑。
微服务鉴权功能划分:

  • gitegg-oauth:Oauth2用户认证和单点登录
  • gitegg-gateway:请求转发和统一鉴权
  • gitegg-system: 读取系统配置的RBAC权限配置并存放到缓存

一、鉴权配置

1、GitEgg-Platform工程下新建gitegg-platform-oauth2工程,用于统一管理OAuth2版本,及统一配置

<!--?xml version="1.0" encoding="UTF-8"?-->

2、在gitegg-oauth工程中引入需要的库

<!--?xml version="1.0" encoding="UTF-8"?-->
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </dependency>
    </dependencies>

</project>

3、JWT可以使用HMAC算法或使用RSA的公钥/私钥对来签名,防止被篡改。首先我们使用keytool生成RSA证书gitegg.jks,复制到gitegg-oauth工程的resource目录下,CMD命令行进入到JDK安装目录的bin目录下, 使用keytool命令生成gitegg.jks证书

keytool -genkey -alias gitegg -keyalg RSA -keystore gitegg.jks

4、新建GitEggUserDetailsServiceImpl.java实现SpringSecurity获取用户信息接口,用于SpringSecurity鉴权时获取用户信息

package com.gitegg.oauth.service;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.oauth2.common.exceptions.UserDeniedAuthorizationException;
import org.springframework.stereotype.Service;
import org.springframework.util.CollectionUtils;
import org.springframework.util.StringUtils;

import com.gitegg.oauth.enums.AuthEnum;
import com.gitegg.platform.base.constant.AuthConstant;
import com.gitegg.platform.base.domain.GitEggUser;
import com.gitegg.platform.base.enums.ResultCodeEnum;
import com.gitegg.platform.base.result.Result;
import com.gitegg.service.system.api.feign.IUserFeign;

import cn.hutool.core.bean.BeanUtil;
import lombok.RequiredArgsConstructor;

/**
 *  实现SpringSecurity获取用户信息接口
 *
 * @author gitegg
 */
@Service
@RequiredArgsConstructor(onConstructor = @__(@Autowired))
public class GitEggUserDetailsServiceImpl implements UserDetailsService {

    private final IUserFeign userFeign;

    private final HttpServletRequest request;

    @Override
    public GitEggUserDetails loadUserByUsername(String username) {

        // 获取登录类型,密码,二维码,验证码
        String authLoginType = request.getParameter(AuthConstant.AUTH_TYPE);

        // 获取客户端id
        String clientId = request.getParameter(AuthConstant.AUTH_CLIENT_ID);

        // 远程调用返回数据
        Result<object> result;

        // 通过手机号码登录
        if (!StringUtils.isEmpty(authLoginType) && AuthEnum.PHONE.code.equals(authLoginType))
        {
            String phone = request.getParameter(AuthConstant.PHONE_NUMBER);
            result = userFeign.queryUserByPhone(phone);
        }
        // 通过账号密码登录
        else if(!StringUtils.isEmpty(authLoginType) && AuthEnum.QR.code.equals(authLoginType))
        {
            result = userFeign.queryUserByAccount(username);
        }
        else
        {
            result = userFeign.queryUserByAccount(username);
        }

        // 判断返回信息
        if (null != result && result.isSuccess()) {
            GitEggUser gitEggUser = new GitEggUser();
            BeanUtil.copyProperties(result.getData(), gitEggUser, false);
            if (gitEggUser == null || gitEggUser.getId() == null) {
                throw new UsernameNotFoundException(ResultCodeEnum.INVALID_USERNAME.msg);
            }

            if (CollectionUtils.isEmpty(gitEggUser.getRoleIdList())) {
                throw new UserDeniedAuthorizationException(ResultCodeEnum.INVALID_ROLE.msg);
            }

            return new GitEggUserDetails(gitEggUser.getId(), gitEggUser.getTenantId(), gitEggUser.getOauthId(),
                gitEggUser.getNickname(), gitEggUser.getRealName(), gitEggUser.getOrganizationId(),
                gitEggUser.getOrganizationName(),
                    gitEggUser.getOrganizationIds(), gitEggUser.getOrganizationNames(), gitEggUser.getRoleId(), gitEggUser.getRoleIds(), gitEggUser.getRoleName(), gitEggUser.getRoleNames(),
                gitEggUser.getRoleIdList(), gitEggUser.getRoleKeyList(), gitEggUser.getResourceKeyList(),
                gitEggUser.getDataPermission(),
                gitEggUser.getAvatar(), gitEggUser.getAccount(), gitEggUser.getPassword(), true, true, true, true,
                AuthorityUtils.createAuthorityList(gitEggUser.getRoleIdList().toArray(new String[gitEggUser.getRoleIdList().size()])));
        } else {
            throw new UsernameNotFoundException(result.getMsg());
        }
    }

}

5、新建AuthorizationServerConfig.java用于认证服务相关配置,正式环境请一定记得修改gitegg.jks配置的密码,这里默认为123456。TokenEnhancer 为登录用户的扩展信息,可以自己定义。

package com.gitegg.oauth.config;

import java.security.KeyPair;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.oauth2.common.DefaultOAuth2AccessToken;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.TokenGranter;
import org.springframework.security.oauth2.provider.token.TokenEnhancer;
import org.springframework.security.oauth2.provider.token.TokenEnhancerChain;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.KeyStoreKeyFactory;

import com.anji.captcha.service.CaptchaService;
import com.gitegg.oauth.granter.GitEggTokenGranter;
import com.gitegg.oauth.service.GitEggClientDetailsServiceImpl;
import com.gitegg.oauth.service.GitEggUserDetails;
import com.gitegg.platform.base.constant.AuthConstant;
import com.gitegg.platform.base.constant.TokenConstant;
import com.gitegg.service.system.api.feign.IUserFeign;

import lombok.RequiredArgsConstructor;
import lombok.SneakyThrows;

/**
 * 认证服务配置
 */
@Configuration
@EnableAuthorizationServer
@RequiredArgsConstructor(onConstructor_ = @Autowired)
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    private final DataSource dataSource;

    private final AuthenticationManager authenticationManager;

    private final UserDetailsService userDetailsService;

    private final IUserFeign userFeign;

    private final RedisTemplate redisTemplate;

    private final CaptchaService captchaService;

    @Value("${captcha.type}")
    private String captchaType;

    /**
     * 客户端信息配置
     */
    @Override
    @SneakyThrows
    public void configure(ClientDetailsServiceConfigurer clients) {
        GitEggClientDetailsServiceImpl jdbcClientDetailsService = new GitEggClientDetailsServiceImpl(dataSource);
        jdbcClientDetailsService.setFindClientDetailsSql(AuthConstant.FIND_CLIENT_DETAILS_SQL);
        jdbcClientDetailsService.setSelectClientDetailsSql(AuthConstant.SELECT_CLIENT_DETAILS_SQL);
        clients.withClientDetails(jdbcClientDetailsService);
    }

    /**
     * 配置授权(authorization)以及令牌(token)的访问端点和令牌服务(token services)
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {

        TokenEnhancerChain tokenEnhancerChain = new TokenEnhancerChain();
        List<tokenenhancer> tokenEnhancers = new ArrayList<>();
        tokenEnhancers.add(tokenEnhancer());
        tokenEnhancers.add(jwtAccessTokenConverter());
        tokenEnhancerChain.setTokenEnhancers(tokenEnhancers);

        // 获取自定义tokenGranter
        TokenGranter tokenGranter = GitEggTokenGranter.getTokenGranter(authenticationManager, endpoints, redisTemplate,
            userFeign, captchaService, captchaType);

        endpoints.authenticationManager(authenticationManager)
                .accessTokenConverter(jwtAccessTokenConverter())
                .tokenEnhancer(tokenEnhancerChain)
                .userDetailsService(userDetailsService)
            .tokenGranter(tokenGranter)
                /**
                 *
                 * refresh_token有两种使用方式:重复使用(true)、非重复使用(false),默认为true
                 * 1.重复使用:access_token过期刷新时, refresh token过期时间未改变,仍以初次生成的时间为准
                 * 2.非重复使用:access_token过期刷新时, refresh_token过期时间延续,在refresh_token有效期内刷新而无需失效再次登录
                 */
                .reuseRefreshTokens(false);
    }

    /**
     * 允许表单认证
     */
    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) {
        security.allowFormAuthenticationForClients()
                .tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }

    /**
     * 使用非对称加密算法对token签名
     */
    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setKeyPair(keyPair());
        return converter;
    }

    /**
     * 从classpath下的密钥库中获取密钥对(公钥+私钥)
     */
    @Bean
    public KeyPair keyPair() {
        KeyStoreKeyFactory factory = new KeyStoreKeyFactory(
                new ClassPathResource("gitegg.jks"), "123456".toCharArray());
        KeyPair keyPair = factory.getKeyPair(
                "gitegg", "123456".toCharArray());
        return keyPair;
    }

    /**
     * JWT内容增强
     */
    @Bean
    public TokenEnhancer tokenEnhancer() {
        return (accessToken, authentication) -> {
            Map<string, object=""> map = new HashMap<>(2);
            GitEggUserDetails user = (GitEggUserDetails) authentication.getUserAuthentication().getPrincipal();
            map.put(TokenConstant.TENANT_ID, user.getTenantId());
            map.put(TokenConstant.OAUTH_ID, user.getOauthId());
            map.put(TokenConstant.USER_ID, user.getId());
            map.put(TokenConstant.ORGANIZATION_ID, user.getOrganizationId());
            map.put(TokenConstant.ORGANIZATION_NAME, user.getOrganizationName());
            map.put(TokenConstant.ORGANIZATION_IDS, user.getOrganizationIds());
            map.put(TokenConstant.ORGANIZATION_NAMES, user.getOrganizationNames());
            map.put(TokenConstant.ROLE_ID, user.getRoleId());
            map.put(TokenConstant.ROLE_NAME, user.getRoleName());
            map.put(TokenConstant.ROLE_IDS, user.getRoleIds());
            map.put(TokenConstant.ROLE_NAMES, user.getRoleNames());
            map.put(TokenConstant.ACCOUNT, user.getAccount());
            map.put(TokenConstant.REAL_NAME, user.getRealName());
            map.put(TokenConstant.NICK_NAME, user.getNickname());
            map.put(TokenConstant.ROLE_ID_LIST, user.getRoleIdList());
            map.put(TokenConstant.ROLE_KEY_LIST, user.getRoleKeyList());
            //不把权限菜单放到jwt里面,当菜单太多时,会导致jwt长度不可控
//            map.put(TokenConstant.RESOURCE_KEY_LIST, user.getResourceKeyList());
            map.put(TokenConstant.DATA_PERMISSION, user.getDataPermission());
            map.put(TokenConstant.AVATAR, user.getAvatar());
            ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(map);
            return accessToken;
        };
    }
}


6、Gateway在认证授权时需要RSA的公钥来验证签名是否合法,所以这里新建GitEggOAuthController的getKey接口用于Gateway获取RSA公钥

    @GetMapping("/public_key")
    public Map<string, object=""> getKey() {
        RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();
        RSAKey key = new RSAKey.Builder(publicKey).build();
        return new JWKSet(key).toJSONObject();
    }

7、新建ResourceServerConfig.java资源服务器配置,放开public_key的读取权限

	@Override
	@SneakyThrows
	public void configure(HttpSecurity http) {
		http.headers().frameOptions().disable();
		http.formLogin()
			.and()
			.authorizeRequests().requestMatchers(EndpointRequest.toAnyEndpoint()).permitAll()
			.and()
			.authorizeRequests()
			.antMatchers(
				"/oauth/public_key").permitAll()
			.anyRequest().authenticated()
			.and()
			.csrf().disable();
	}

8、在gitegg-service-system新建InitResourceRolesCacheRunner.java实现CommandLineRunner接口,用于系统启动时加载RBAC权限配置信息到缓存

package com.gitegg.service.system.component;

import java.util.*;
import java.util.stream.Collectors;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.CommandLineRunner;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

import com.gitegg.platform.base.constant.AuthConstant;
import com.gitegg.service.system.entity.Resource;
import com.gitegg.service.system.service.IResourceService;

import cn.hutool.core.collection.CollectionUtil;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;

/**
 * 容器启动完成加载资源权限数据到缓存
 */
@Slf4j
@RequiredArgsConstructor(onConstructor_ = @Autowired)
@Component
public class InitResourceRolesCacheRunner implements CommandLineRunner {

    private final RedisTemplate redisTemplate;

    private final IResourceService resourceService;

    /**
     * 是否开启租户模式
     */
    @Value(("${tenant.enable}"))
    private Boolean enable;

    @Override
    public void run(String... args) {

        log.info("InitResourceRolesCacheRunner running");

        // 查询系统角色和权限的关系
        List<resource> resourceList = resourceService.queryResourceRoleIds();

        // 判断是否开启了租户模式,如果开启了,那么角色权限需要按租户进行分类存储
        if (enable) {
            Map<long, list<resource="">> resourceListMap =
                resourceList.stream().collect(Collectors.groupingBy(Resource::getTenantId));
            resourceListMap.forEach((key, value) -> {
                String redisKey = AuthConstant.TENANT_RESOURCE_ROLES_KEY + key;
                redisTemplate.delete(redisKey);
                addRoleResource(redisKey, value);
                System.out.println(redisTemplate.opsForHash().entries(redisKey).size());
            });
        } else {
            redisTemplate.delete(AuthConstant.RESOURCE_ROLES_KEY);
            addRoleResource(AuthConstant.RESOURCE_ROLES_KEY, resourceList);
        }
    }

    private void addRoleResource(String key, List<resource> resourceList) {
        Map<string, list<string="">> resourceRolesMap = new TreeMap<>();
        Optional.ofNullable(resourceList).orElse(new ArrayList<>()).forEach(resource -> {
            // roleId -> ROLE_{roleId}
            List<string> roles = Optional.ofNullable(resource.getRoleIds()).orElse(new ArrayList<>()).stream()
                .map(roleId -> AuthConstant.AUTHORITY_PREFIX + roleId).collect(Collectors.toList());
            if (CollectionUtil.isNotEmpty(roles)) {
                resourceRolesMap.put(resource.getResourceUrl(), roles);
            }
        });
        redisTemplate.opsForHash().putAll(key, resourceRolesMap);
    }
}

9、新建网关服务gitegg-gateway,作为Oauth2的资源服务、客户端服务使用,对访问微服务的请求进行转发、统一校验认证和鉴权操作,引入相关依赖

<!--?xml version="1.0" encoding="UTF-8"?-->

10、新建AuthResourceServerConfig.java对gateway网关服务进行配置安全配置,需要使用@EnableWebFluxSecurity而非@EnableWebSecurity,因为SpringCloud Gateway基于WebFlux

package com.gitegg.gateway.config;

    @Bean
    public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
        http.oauth2ResourceServer().jwt()
                .jwtAuthenticationConverter(jwtAuthenticationConverter());
        // 自定义处理JWT请求头过期或签名错误的结果
        http.oauth2ResourceServer().authenticationEntryPoint(authServerAuthenticationEntryPoint);
        // 对白名单路径,直接移除JWT请求头,不移除的话,后台会校验jwt
        http.addFilterBefore(whiteListRemoveJwtFilter, SecurityWebFiltersOrder.AUTHENTICATION);
        http.authorizeExchange()

                .and()
                .cors()
                .and().csrf().disable();

        return http.build();
    }

    /**
     * ServerHttpSecurity没有将jwt中authorities的负载部分当做Authentication,需要把jwt的Claim中的authorities加入

     */
    @Bean
    public Converter<jwt, ?="" extends="" mono<?="" abstractauthenticationtoken="">> jwtAuthenticationConverter() {

        JwtAuthenticationConverter jwtAuthenticationConverter = new JwtAuthenticationConverter();
        jwtAuthenticationConverter.setJwtGrantedAuthoritiesConverter(jwtGrantedAuthoritiesConverter);
        return new ReactiveJwtAuthenticationConverterAdapter(jwtAuthenticationConverter);
    }
}

11、新建AuthorizationManager.java实现ReactiveAuthorizationManager接口,用于自定义权限校验

package com.gitegg.gateway.auth;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.http.HttpMethod;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.security.authorization.AuthorizationDecision;
import org.springframework.security.authorization.ReactiveAuthorizationManager;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.web.server.authorization.AuthorizationContext;
import org.springframework.stereotype.Component;
import org.springframework.util.AntPathMatcher;
import org.springframework.util.PathMatcher;
import org.springframework.util.StringUtils;

import com.gitegg.platform.base.constant.AuthConstant;

import cn.hutool.core.convert.Convert;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import reactor.core.publisher.Mono;

/**
 * 网关鉴权管理器
 */
@Slf4j
@Component
@RequiredArgsConstructor(onConstructor_ = @Autowired)
public class AuthorizationManager implements ReactiveAuthorizationManager<authorizationcontext> {

    private final RedisTemplate redisTemplate;

    /**
     * 是否开启租户模式
     */
    @Value(("${tenant.enable}"))
    private Boolean enable;

    @Override
    public Mono<authorizationdecision> check(Mono<authentication> mono, AuthorizationContext authorizationContext) {
        ServerHttpRequest request = authorizationContext.getExchange().getRequest();
        String path = request.getURI().getPath();
        PathMatcher pathMatcher = new AntPathMatcher();

        // 对应跨域的预检请求直接放行
        if (request.getMethod() == HttpMethod.OPTIONS) {
            return Mono.just(new AuthorizationDecision(true));
        }

        // token为空拒绝访问
        String token = request.getHeaders().getFirst(AuthConstant.JWT_TOKEN_HEADER);
        if (StringUtils.isEmpty(token)) {
            return Mono.just(new AuthorizationDecision(false));
        }

        //  如果开启了租户模式,但是请求头里没有租户信息,那么拒绝访问
        String tenantId = request.getHeaders().getFirst(AuthConstant.TENANT_ID);
        if (enable && StringUtils.isEmpty(tenantId)) {
            return Mono.just(new AuthorizationDecision(false));
        }

        String redisRoleKey = AuthConstant.TENANT_RESOURCE_ROLES_KEY;
        // 判断是否开启了租户模式,如果开启了,那么按租户分类的方式获取角色权限
        if (enable) {
            redisRoleKey += tenantId;
        } else {
            redisRoleKey = AuthConstant.RESOURCE_ROLES_KEY;
        }

        //  缓存取资源权限角色关系列表
        Map<object, object=""> resourceRolesMap = redisTemplate.opsForHash().entries(redisRoleKey);
        Iterator<object> iterator = resourceRolesMap.keySet().iterator();

        //请求路径匹配到的资源需要的角色权限集合authorities统计
        List<string> authorities = new ArrayList<>();
        while (iterator.hasNext()) {
            String pattern = (String) iterator.next();
            if (pathMatcher.match(pattern, path)) {
                authorities.addAll(Convert.toList(String.class, resourceRolesMap.get(pattern)));
            }
        }
        Mono<authorizationdecision> authorizationDecisionMono = mono
                .filter(Authentication::isAuthenticated)
                .flatMapIterable(Authentication::getAuthorities)
                .map(GrantedAuthority::getAuthority)
                .any(roleId -> {
                    // roleId是请求用户的角色(格式:ROLE_{roleId}),authorities是请求资源所需要角色的集合
                    log.info("访问路径:{}", path);
                    log.info("用户角色roleId:{}", roleId);
                    log.info("资源需要权限authorities:{}", authorities);
                    return authorities.contains(roleId);
                })
                .map(AuthorizationDecision::new)
                .defaultIfEmpty(new AuthorizationDecision(false));
        return authorizationDecisionMono;
    }
}

12、新建AuthGlobalFilter.java全局过滤器,解析用户请求信息,将用户信息及租户信息放在请求的Header中,这样后续服务就不需要解析JWT令牌了,可以直接从请求的Header中获取到用户和租户信息。

package com.gitegg.gateway.filter;

import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import java.text.ParseException;
import java.util.HashMap;
import java.util.Map;
import java.util.function.Consumer;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.gateway.filter.GatewayFilterChain;
import org.springframework.cloud.gateway.filter.GlobalFilter;
import org.springframework.core.Ordered;
import org.springframework.http.HttpHeaders;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;

import com.gitegg.platform.base.constant.AuthConstant;
import com.nimbusds.jose.JWSObject;

import cn.hutool.core.util.StrUtil;
import lombok.extern.slf4j.Slf4j;
import reactor.core.publisher.Mono;

/**
 * 将登录用户的JWT转化成用户信息的全局过滤器
 */
@Slf4j
@Component
public class AuthGlobalFilter implements GlobalFilter, Ordered {

    /**
     * 是否开启租户模式
     */
    @Value(("${tenant.enable}"))
    private Boolean enable;

    @Override
    public Mono<void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {

        String tenantId = exchange.getRequest().getHeaders().getFirst(AuthConstant.TENANT_ID);

        String token = exchange.getRequest().getHeaders().getFirst(AuthConstant.JWT_TOKEN_HEADER);

        if (StrUtil.isEmpty(tenantId) && StrUtil.isEmpty(token)) {
            return chain.filter(exchange);
        }

        Map<string, string=""> addHeaders = new HashMap<>();

        // 如果系统配置已开启租户模式,设置tenantId
        if (enable && StrUtil.isEmpty(tenantId)) {
            addHeaders.put(AuthConstant.TENANT_ID, tenantId);
        }

        if (!StrUtil.isEmpty(token)) {
        try {
            //从token中解析用户信息并设置到Header中去
            String realToken = token.replace("Bearer ", "");
            JWSObject jwsObject = JWSObject.parse(realToken);
            String userStr = jwsObject.getPayload().toString();
            log.info("AuthGlobalFilter.filter() User:{}", userStr);
            addHeaders.put(AuthConstant.HEADER_USER, URLEncoder.encode(userStr, "UTF-8"));

        } catch (ParseException | UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }

    Consumer<httpheaders> httpHeaders = httpHeader -> {
        addHeaders.forEach((k, v) -> {
            httpHeader.set(k, v);
        });
    };

    ServerHttpRequest request = exchange.getRequest().mutate().headers(httpHeaders).build();
    exchange = exchange.mutate().request(request).build();
        return chain.filter(exchange);
    }

    @Override
    public int getOrder() {
        return 0;
    }
}

13、在Nacos中添加权限相关配置信息:

spring:
  jackson:
    time-zone: Asia/Shanghai
    date-format: yyyy-MM-dd HH:mm:ss
  security:
    oauth2:
      resourceserver:
        jwt:
          jwk-set-uri: 'http://127.0.0.1/gitegg-oauth/oauth/public_key'
# 多租户配置
tenant:
  # 是否开启租户模式
  enable: true
  # 需要排除的多租户的表
  exclusionTable:
    - "t_sys_district"
    - "t_sys_tenant"
    - "t_sys_role"
    - "t_sys_resource"
    - "t_sys_role_resource"
  # 租户字段名称
  column: tenant_id
# 网关放行白名单,配置白名单路径
white-list:
  urls:
    - "/gitegg-oauth/oauth/public_key"

二、注销登录使JWT失效

因为JWT是无状态的且不在服务端储存,所以,当系统在执行退出登录时就无法使JWT失效,我们有两种方式拒绝注销登录后的JWT:

  • JWT白名单:每次登录成功就将JWT存到缓存中,缓存有效期和JWT有效期保持一致,注销登录就将JWT从缓存中移出。Gateway每次认证授权先从缓存JWT白名单中获取是否存在该JWT,存在则继续校验,不存在则拒绝访问。

  • JWT黑名单:每当注销登录时,将JWT存到缓存中,解析JWT的到期时间,将缓存过期时间设置为和JWT一致。Gateway每次认证授权先从缓存中获取JWT是否存在于黑名单中,存在则拒绝访问,不存在则继续校验。

不管是白名单还是黑名单,实现方式的原理都基本一致,就是将JWT先存放到缓存,再根据不同的状态进行判断JWT是否有效,下面是两种方式的优缺点分析:

  • 黑名单功能分析:优点是存放到缓存的数据量将小于白名单方式存放的数据量,缺点是无法获知当前签发了多少JWT,当前在线多少登录用户。
  • 白名单功能分析:优点是当我们需要统计在线用户的时候,白名单方式可以近似的获取到当前系统登录用户,可以扩展踢出登录用户的功能。缺点是数据存储量大,且大量token存在缓存中需要进行校验,万一被攻击会导致大量信息泄露。

综上考虑,还是采用黑名单的方式来实现注销登录功能,实时统计在线人数和踢出用户等功能作为扩展功能来开发,不在登录注销逻辑中掺杂太多的业务处理逻辑,使系统保持低耦合。

为了使JWT有效信息最大程度保证准确性,注销登录除了在系统点击退出登录按钮,还需要监测是否直接关闭页面,关闭浏览器事件,来执行调用系统注销接口

token和refresh_token的过期时间不一致,都在其解析之后的exp字段。因为我们定制了黑名单模式,当用户点击退出登录之后,我们会把refresh_token也加入黑名单,在refresh_token获取刷新token的时候,需要定制校验refresh_token是否被加入到黑名单。

1、退出登录接口将token和refresh_token加入黑名单

        /**
     * 退出登录需要需要登录的一点思考:
     * 1、如果不需要登录,那么在调用接口的时候就需要把token传过来,且系统不校验token有效性,此时如果系统被攻击,不停的大量发送token,最后会把redis充爆
     * 2、如果调用退出接口必须登录,那么系统会调用token校验有效性,refresh_token通过参数传过来加入黑名单
     * 综上:选择调用退出接口需要登录的方式
     * @param request
     * @return
     */
    @PostMapping("/logout")
    public Result logout(HttpServletRequest request) {

        String token = request.getHeader(AuthConstant.JWT_TOKEN_HEADER);
        String refreshToken = request.getParameter(AuthConstant.REFRESH_TOKEN);
        long currentTimeSeconds = System.currentTimeMillis() / GitEggConstant.Number.THOUSAND;

        // 将token和refresh_token同时加入黑名单
        String[] tokenArray = new String[GitEggConstant.Number.TWO];
        tokenArray[GitEggConstant.Number.ZERO] = token.replace("Bearer ", "");
        tokenArray[GitEggConstant.Number.ONE] = refreshToken;
        for (int i = GitEggConstant.Number.ZERO; i < tokenArray.length; i++) {
            String realToken = tokenArray[i];
            JSONObject jsonObject = JwtUtils.decodeJwt(realToken);
            String jti = jsonObject.getAsString("jti");
            Long exp = Long.parseLong(jsonObject.getAsString("exp"));
            if (exp - currentTimeSeconds > GitEggConstant.Number.ZERO) {
                redisTemplate.opsForValue().set(AuthConstant.TOKEN_BLACKLIST + jti, jti, (exp - currentTimeSeconds), TimeUnit.SECONDS);
            }
        }
        return Result.success();
    }

2、Gateway在AuthorizationManager中添加token是否加入黑名单的判断

        //如果token被加入到黑名单,就是执行了退出登录操作,那么拒绝访问
        String realToken = token.replace("Bearer ", "");
        try {
            JWSObject jwsObject = JWSObject.parse(realToken);
            Payload payload = jwsObject.getPayload();
            JSONObject jsonObject = payload.toJSONObject();
            String jti = jsonObject.getAsString("jti");
            String blackListToken = (String)redisTemplate.opsForValue().get(AuthConstant.TOKEN_BLACKLIST + jti);
            if (!StringUtils.isEmpty(blackListToken)) {
                return Mono.just(new AuthorizationDecision(false));
            }
        } catch (ParseException e) {
            e.printStackTrace();
        }

3、自定义DefaultTokenService,校验refresh_token是否被加入黑名单

@Slf4j
public class GitEggTokenServices extends DefaultTokenServices {

    private final RedisTemplate redisTemplate;

    public GitEggTokenServices(RedisTemplate redisTemplate)
    {
        this.redisTemplate = redisTemplate;
    }

    @Transactional(
            noRollbackFor = {InvalidTokenException.class, InvalidGrantException.class}
    )
    @Override
    public OAuth2AccessToken refreshAccessToken(String refreshTokenValue, TokenRequest tokenRequest) throws AuthenticationException {

        JSONObject jsonObject = null;
        String jti = null;
        //如果refreshToken被加入到黑名单,就是执行了退出登录操作,那么拒绝访问
        try {
            JWSObject jwsObject = JWSObject.parse(refreshTokenValue);
            Payload payload = jwsObject.getPayload();
            jsonObject = payload.toJSONObject();
            jti = jsonObject.getAsString(TokenConstant.JTI);
            String blackListToken = (String)redisTemplate.opsForValue().get(AuthConstant.TOKEN_BLACKLIST + jti);
            if (!StringUtils.isEmpty(blackListToken)) {
                throw new InvalidTokenException("Invalid refresh token (blackList): " + refreshTokenValue);
            }
        } catch (ParseException e) {
            log.error("获取refreshToken黑名单时发生错误:{}", e);
        }

       OAuth2AccessToken oAuth2AccessToken = super.refreshAccessToken(refreshTokenValue, tokenRequest);

        // RefreshToken不支持重复使用,如果使用一次,则加入黑名单不再允许使用,当刷新token执行完之后,即校验过RefreshToken之后,才执行存redis操作
        if (null != jsonObject && !StringUtils.isEmpty(jti)) {
            long currentTimeSeconds = System.currentTimeMillis() / GitEggConstant.Number.THOUSAND;
            Long exp = Long.parseLong(jsonObject.getAsString(TokenConstant.EXP));
            if (exp - currentTimeSeconds > GitEggConstant.Number.ZERO) {
                redisTemplate.opsForValue().set(AuthConstant.TOKEN_BLACKLIST + jti, jti, (exp - currentTimeSeconds), TimeUnit.SECONDS);
            }
        }

        return oAuth2AccessToken;
    }
}
测试:

1、使用密码模式获取token

3、再次执行refresh_token刷新token,此时因为refresh_token已经调用过一次,所以这里不能再次使用

三、前端自动使用refresh_token刷新token

1、使用axios-auth-refresh公共组件,当后台状态返回401时,进行token刷新操作

import axios from 'axios'
import createAuthRefreshInterceptor from 'axios-auth-refresh'
import store from '@/store'
import storage from 'store'
import { serialize } from '@/utils/util'
import notification from 'ant-design-vue/es/notification'
import modal from 'ant-design-vue/es/modal'
import { VueAxios } from './axios'
import { ACCESS_TOKEN, REFRESH_ACCESS_TOKEN } from '@/store/mutation-types'

// 创建 axios 实例
const request = axios.create({
  // API 请求的默认前缀
  baseURL: process.env.VUE_APP_API_BASE_URL,
  timeout: 30000 // 请求超时时间
})

// 当token失效时,需要调用的刷新token的方法
const refreshAuthLogic = failedRequest =>
  axios.post(process.env.VUE_APP_API_BASE_URL + '/gitegg-oauth/oauth/token',
  serialize({ client_id: process.env.VUE_APP_CLIENT_ID,
      client_secret: process.env.VUE_APP_CLIENT_SECRET,
      grant_type: 'refresh_token',
      refresh_token: storage.get(REFRESH_ACCESS_TOKEN)
    }),
    {
      headers: { 'TenantId': process.env.VUE_APP_TENANT_ID, 'Content-Type': 'application/x-www-form-urlencoded' }
    }
    ).then(tokenRefreshResponse => {
      if (tokenRefreshResponse.status === 200 && tokenRefreshResponse.data && tokenRefreshResponse.data.success) {
        const result = tokenRefreshResponse.data.data
        storage.set(ACCESS_TOKEN, result.tokenHead + result.token, result.expiresIn * 1000)
        storage.set(REFRESH_ACCESS_TOKEN, result.refreshToken, result.refreshExpiresIn * 1000)
        failedRequest.response.config.headers['Authorization'] = result.tokenHead + result.token
      }
      return Promise.resolve()
})

// 初始化刷新token拦截器
createAuthRefreshInterceptor(request, refreshAuthLogic, {
  pauseInstanceWhileRefreshing: true // 当刷新token执行时,暂停其他请求

四、记住密码功能实现

有时候,在我们在可信任的电脑上可以实现记住密码功能,前后端分离项目的实现只需要把密码记录到localstorage中,然后每次访问登录界面时,自动填入即可。这里先使用明文进行存储,为了系统安全,在实际应用过程需要将密码加密存储,后台校验加密后的密码
1、在created中读取是否记住密码

created () {
    this.queryCaptchaType()
      this.$nextTick(() => {
        const rememberMe = storage.get(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-rememberMe')
          if (rememberMe) {
            const username = storage.get(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-username')
            const password = storage.get(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-password')
            if (username !== '' && password !== '') {
            this.form.setFieldsValue({ 'username': username })
            this.form.setFieldsValue({ 'password': password })
            this.form.setFieldsValue({ 'rememberMe': true })
          }
        }
      })
  },

2、每次登录成功之后,根据是否勾选记住密码来确定是否填入用户名密码

     // 判断是否记住密码
      const rememberMe = this.form.getFieldValue('rememberMe')
      const username = this.form.getFieldValue('username')
      const password = this.form.getFieldValue('password')
      if (rememberMe && username !== '' && password !== '') {
          storage.set(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-username', username, 60 * 60 * 24 * 7 * 1000)
          storage.set(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-password', password, 60 * 60 * 24 * 7 * 1000)
          storage.set(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-rememberMe', true, 60 * 60 * 24 * 7 * 1000)
      } else {
         storage.remove(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-username')
         storage.remove(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-password')
         storage.remove(process.env.VUE_APP_TENANT_ID + '-' + process.env.VUE_APP_CLIENT_ID + '-rememberMe')
      }

五、密码尝试次数过多则锁定账户

从系统安全方面来讲,我们需要支持防止用户账户被暴力破解的措施,目前技术已经能够轻松破解大多数的验证码,这为暴力破解用户账户提供了方便,那么这里我们的系统需要密码尝试次数过多锁定账户的功能。SpringSecurity的UserDetails接口定义了isAccountNonLocked方法来判断账户是否被锁定

public interface UserDetails extends Serializable {
    Collection<!--? extends GrantedAuthority--> getAuthorities();

    String getPassword();

    String getUsername();

    boolean isAccountNonExpired();

    boolean isAccountNonLocked();

    boolean isCredentialsNonExpired();

    boolean isEnabled();
}

1、自定义LoginFailureListener事件监听器,监听SpringSecurity抛出AuthenticationFailureBadCredentialsEvent异常事件,使用Redis计数器,记录账号错误密码次数

/**
 * 当登录失败时的调用,当密码错误过多时,则锁定账户
 * @author GitEgg
 * @date 2021-03-12 17:57:05
 **/
@Slf4j
@Component
@RequiredArgsConstructor(onConstructor_ = @Autowired)
public class LoginFailureListener implements ApplicationListener<authenticationfailurebadcredentialsevent> {

    private final UserDetailsService userDetailsService;

    private final RedisTemplate redisTemplate;

    @Value("${system.maxTryTimes}")
    private int maxTryTimes;

    @Override
    public void onApplicationEvent(AuthenticationFailureBadCredentialsEvent event) {

        if (event.getException().getClass().equals(UsernameNotFoundException.class)) {
            return;
        }

        String userName = event.getAuthentication().getName();

        GitEggUserDetails user = (GitEggUserDetails) userDetailsService.loadUserByUsername(userName);

        if (null != user) {
            Object lockTimes = redisTemplate.boundValueOps(AuthConstant.LOCK_ACCOUNT_PREFIX + user.getId()).get();
            if(null == lockTimes || (int)lockTimes <= maxTryTimes){
                redisTemplate.boundValueOps(AuthConstant.LOCK_ACCOUNT_PREFIX + user.getId()).increment(GitEggConstant.Number.ONE);
            }
        }
    }
}

2、GitEggUserDetailsServiceImpl方法查询Redis记录的账号锁定次数

            // 判断账号是否被锁定(账户过期,凭证过期等可在此处扩展)
            Object lockTimes = redisTemplate.boundValueOps(AuthConstant.LOCK_ACCOUNT_PREFIX + gitEggUser.getId()).get();
            boolean accountNotLocked = true;
            if(null != lockTimes && (int)lockTimes >= maxTryTimes){
                accountNotLocked = false;
            }

六、登录时是否需要输入验证码

验证码设置前三次(可配置)登录时,不需要输入验证码,当密码尝试次数大于三次时,需要输入验证码,登录方式的一个思路:初始进入登录界面,用户可选择自己的登录方式,我们系统OAuth默认设置了三种登录方式:

  • 用户名+密码登录
  • 用户名+密码+验证码
  • 手机号+验证码登录

系统默认采用用户名+密码登录,当默认的用户名密码登录错误次数(默认一次)超过系统配置的最大次数时,则必须输入验证码登录,当验证码也超过一定次数时(默认五次),都不行则锁定账户二小时之后才可以继续尝试。因为考虑到有些系统可能不会用到短信验证码等,所以这里作为一个扩展功能:如果有需要可以在用户名密码错误过多时,强制只用短信验证码才能登录,且一定要设置超过错误次数就锁定。
1、在自定义的GitEggUserDetailsServiceImpl增加账号判断

            // 从Redis获取账号密码错误次数
            Object lockTimes = redisTemplate.boundValueOps(AuthConstant.LOCK_ACCOUNT_PREFIX + gitEggUser.getId()).get();

            // 判断账号密码输入错误几次,如果输入错误多次,则锁定账号
            // 输入错误大于配置的次数,必须选择captcha或sms_captcha
            if (null != lockTimes && (int)lockTimes >= maxNonCaptchaTimes && ( StringUtils.isEmpty(authGrantType) || (!StringUtils.isEmpty(authGrantType)
                    && !AuthEnum.SMS_CAPTCHA.code.equals(authGrantType) && !AuthEnum.CAPTCHA.code.equals(authGrantType)))) {
                throw new GitEggOAuth2Exception(ResultCodeEnum.INVALID_PASSWORD_CAPTCHA.msg);
            }

            // 判断账号是否被锁定(账户过期,凭证过期等可在此处扩展)
            if(null != lockTimes && (int)lockTimes >= maxTryTimes){
                throw new LockedException(ResultCodeEnum.PASSWORD_TRY_MAX_ERROR.msg);
            }

            // 判断账号是否被禁用
            String userStatus = gitEggUser.getStatus();
            if (String.valueOf(GitEggConstant.DISABLE).equals(userStatus)) {
                throw new DisabledException(ResultCodeEnum.DISABLED_ACCOUNT.msg);
            }

2、自定义OAuth2拦截异常并统一处理

/**
 * 自定义Oauth异常拦截处理器
 */
@Slf4j
@RestControllerAdvice
public class GitEggOAuth2ExceptionHandler {

    @ExceptionHandler(InvalidTokenException.class)
    public Result handleInvalidTokenException(InvalidTokenException e) {
        return Result.error(ResultCodeEnum.UNAUTHORIZED);
    }

    @ExceptionHandler({UsernameNotFoundException.class})
    public Result handleUsernameNotFoundException(UsernameNotFoundException e) {
        return Result.error(ResultCodeEnum.INVALID_USERNAME_PASSWORD);
    }

    @ExceptionHandler({InvalidGrantException.class})
    public Result handleInvalidGrantException(InvalidGrantException e) {
        return Result.error(ResultCodeEnum.INVALID_USERNAME_PASSWORD);
    }

    @ExceptionHandler(InternalAuthenticationServiceException.class)
    public Result handleInvalidGrantException(InternalAuthenticationServiceException e) {
        Result result = Result.error(ResultCodeEnum.INVALID_USERNAME_PASSWORD);
        if (null != e) {
            String errorMsg = e.getMessage();
            if (ResultCodeEnum.INVALID_PASSWORD_CAPTCHA.getMsg().equals(errorMsg)) {
                //必须使用验证码
                result = Result.error(ResultCodeEnum.INVALID_PASSWORD_CAPTCHA);
            }
            else if (ResultCodeEnum.PASSWORD_TRY_MAX_ERROR.getMsg().equals(errorMsg)) {
                //账号被锁定
                result = Result.error(ResultCodeEnum.PASSWORD_TRY_MAX_ERROR);
            }
            else if (ResultCodeEnum.DISABLED_ACCOUNT.getMsg().equals(errorMsg)) {
                //账号被禁用
                result = Result.error(ResultCodeEnum.DISABLED_ACCOUNT);
            }
        }
        return result;
    }
}

3、前端登录页面增加判断,默认采用password方式登录,当错误达到一定次数时,必须使用验证码登录

    requestFailed (err) {
      this.isLoginError = true
      if (err && err.code === 427) {
        // 密码错误次数超过最大限值,请选择验证码模式登录
        if (this.customActiveKey === 'tab_account') {
            this.grantType = 'captcha'
        } else {
            this.grantType = 'sms_captcha'
        }
        this.loginErrorMsg = err.msg
        if (this.loginCaptchaType === 'sliding') {
            this.$refs.verify.show()
        }
      } else if (err) {
            this.loginErrorMsg = err.msg
      }
    }

备注:
一、当验证报401时:
进行 /auth/token 的post请求时,没有进行http basic认证。
什么是http Basic认证?
http协议的一种认证方式,将客户端id和客户端密码按照“客户端ID:客户端密码”的格式拼接,并用base64编码,放在
header中请求服务端。例子如下:
Authorization:Basic ASDLKFALDSFAJSLDFKLASD=
ASDLKFALDSFAJSLDFKLASD= 就是 客户端ID:客户端密码 的64编码
二、JWT一直不过期:
在自定义TokenEnhancer时,将毫秒加入到了过期时间中,在鉴权解析时,OAuth2是按照秒来解析,所以生成的过期时间非常大,导致token一直未过期。
