实验四 Web服务器2

基于华为鲲鹏云服务器CentOS中（或Ubuntu），使用Linux Socket实现：
1. Web服务器的客户端服务器，提交程序运行截图
2. 实现GET即可，请求，响应要符合HTTP协议规范
3. 服务器部署到华为云服务器，浏览器用本机的
4. 把服务器部署到试验箱。（加分项）

#include <stdio.h>

static char copybuf[16384];

extern int TIMEOUT;

int copy(FILE *read_f, FILE *write_f)
{
  int n;
  int wrote;
  alarm(TIMEOUT);
  while (n = fread(copybuf,1,sizeof(copybuf),read_f)) {
    alarm(TIMEOUT);
    wrote = fwrite(copybuf,n,1,write_f);
    alarm(TIMEOUT);
    if (wrote < 1)
    	return -1;
  }
  alarm(0);
  return 0;
}

在httpd.c文件中增加声明#define HTTPD_DOCUMENT_ROOT "."

进行编译gcc *.c -o webserver -lpthread
