ServiceStack.Redis 的 ASP.NET Core 扩展库

开发技术 开发技术 6天前 7次浏览

给大家安利一款 ServiceStack.Redis 的 ASP.NET Core 扩展库,它是基于 ServiceStack.Redis.Core 开发的。 简单易用,开源免费,使用ASP.NET Core自身提供的DI容器来实现针对服务的注册和消费。直接在程序启动时注册到服务中即可完成全部配置,对于小白用户也可快速上手Redis缓存和Redis分布式缓存。

已解除ServiceStack.Redis每小时6000次请求的限制

Install Package

https://www.nuget.org/packages/ServiceStack.Redis.Extension.AspNetCore

Configure

Startup.cs

Single Server

public void ConfigureServices(IServiceCollection services)
{
    services.AddDistributedServiceStackRedisCache(options =>
    {
        // default single server: 127.0.0.1:6379
        // services.AddServiceStackRedisCache();
        
        // customize single server
        services.AddServiceStackRedisCache(options =>{
        	options.SingleServer = "123456@127.0.0.1:6379";
        });
    }
                                                  
    services.AddControllers();
}

Read and write separation

public void ConfigureServices(IServiceCollection services)
{
    services.AddServiceStackRedisCache(options =>
    {
        options.ReadWriteServers = new[]
        {
            "192.168.1.1:6379", "123456@192.168.1.2:6379", "123456@192.168.1.3:6379", "123456@192.168.1.4:6379"
        };
        options.ReadOnlyServers = new[]
        {
            "192.168.1.1:6379", "123456@192.168.1.3:6379"
        };
    });

    services.AddControllers();
}

Load from configuration

public void ConfigureServices(IServiceCollection services)
{
   
services.AddServiceStackRedisCache(Configuration.GetSection("ServiceStackRedisOptions"));

    services.AddControllers();
}

    }

    [HttpGet]
    public IEnumerable<WeatherForecast> Get()
    {

            array = Enumerable.Range(1, 5).Select(index => new WeatherForecast

                Date = DateTime.Now.AddDays(index),
                TemperatureC = rng.Next(-20, 55),
                Summary = Summaries[rng.Next(Summaries.Length)]
            }).ToArray();

            // Cache for 30 minutes
            _redisCache.Set("WeatherForecast", array, 60 * 1 * 30);
