HTTP基本协议(查看网页代码)

此示例已实现查看网页的代码来理解HTTP基本协议：

（返回的是百度首页的网页代码）

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.Socket;


public class HttpTest {

    /**
     * @param args
     */
    public static void main(String[] args)  throws Exception{
        // TODO Auto-generated method stub
    Socket s=new Socket("202.108.22.5",80);
    PrintWriter pw=new PrintWriter(new OutputStreamWriter(s.getOutputStream()));
    pw.println("GET  / HTTP/1.1");
    pw.println("Host:www.baidu.com");
    pw.println("Context-Type:text/html");
    pw.println();
    pw.flush();
    BufferedReader br=new BufferedReader(new InputStreamReader(s.getInputStream()));
    String str="";
    while((str=br.readLine())!=null)
    {
        System.out.println(str);
    }
    br.close();
    pw.close();
    s.close();
    }

}
