httpserver 第一个server代码模拟

 

 

1 server方法内分为三步骤，

start()   receive()  stop()

 

2 客户端就是浏览器，建立好服务端后在客户端中输入 ip：端口即可访问到

 

3 代码如下：

 

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

/**
 * 创建服务器，并启动
 * @author Administrator
 在浏览器中输入  http://localhost:8888  可以在控制台打印浏览器请求过来的信息
 
 打印结果如下：
 GET / HTTP/1.1
Host: localhost:8888
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
