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();
     }

 }
