网络编程（自定义浏览器-Tomcat服务器）

//一、获取客户端HTTP协议
//1、模拟http请求，先开启一个serverSocket服务，开启下面类Server.main()方法
//2、然后开启浏览器，输入http://127.0.0.1:10002
//在服务器窗口即打印出
//GET / HTTP/1.1
//Accept: */*
//Accept-Language: zh-cn
//User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.
//0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Cent
//er PC 6.0; .NET4.0C; .NET4.0E)
//Accept-Encoding: gzip, deflate
//Host: 127.0.0.1:10002
//Connection: Keep-Alive

import java.net.*;import java.io.*;class Server{public static void main(String[] args) throws Exception{final ServerSocket server = new ServerSocket(10002);while(true){final Socket socket = server.accept();new Thread(new Runnable(){public void run(){try{String ip = socket.getInetAddress().getHostAddress();System.out.println(ip + ".....connected");BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));String line = null;while((line = br.readLine())!=null){System.out.println(line);}}catch (Exception e){e.printStackTrace();System.out.println("服务器有问题");}finally{System.out.println("finally");if(socket !=null)try{socket.close();}catch (Exception e){System.out.println("socket 关闭失败");}}}}).start();}}}

二、获取服务器返回的http协议
//1、开启本地的tomcat服务
//2、将下面Client2中第一句代码的端口改为 tomcat的端口，运行Client2的main()
//即可获取
/*
HTTP/1.1 505 HTTP Version Not Supported
Server: Apache-Coyote/1.1
Date: Mon, 26 May 2014 05:58:58 GMT
Connection: close
*/

class Client2{public static void main(String[] args) throws Exception{Socket socket = new Socket(InetAddress.getByName("127.0.0.1"),10002);PrintWriter pw = new PrintWriter(socket.getOutputStream(),true);pw.println("#break");pw.println("GET / HTTP/1.1");pw.println("Accept: */*");pw.println("Accept-Language: zh-cn");pw.println("Accept-Encoding: gzip, deflate");pw.println("Host: 127.0.0.1:10002");pw.println("Connection: closed");pw.println();pw.println();pw.println("#break");BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));String line = null;while((line = br.readLine())!=null){System.out.println(line);}socket.close();}}

//三、模拟http协议发送、与接收
//开启Server2 Client2 即模拟实现

class Server2{public static void main(String[] args) throws Exception{final ServerSocket server = new ServerSocket(10002);while(true){final Socket socket = server.accept();new Thread(new Runnable(){public void run(){try{String ip = socket.getInetAddress().getHostAddress();System.out.println(ip + ".....connected");BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));String line = null;String breakPoint = br.readLine();while((line = br.readLine())!=null){if(breakPoint.equals(line))break;elseSystem.out.println(line);}PrintWriter pw = new PrintWriter(socket.getOutputStream(),true);pw.println("HTTP/1.1 505 HTTP Version Not Supported");pw.println("Server: Apache-Coyote/1.1");pw.println("Date: Mon, 26 May 2014 05:58:58 GMT");pw.println("Connection: close");}catch (Exception e){e.printStackTrace();System.out.println("服务器有问题");}finally{if(socket !=null)try{socket.close();}catch (Exception e){System.out.println("socket 关闭失败");}}}}).start();}}}
