目标：通过socket 模拟HTTP协议连接 tomcat，做一次GET请求

 

HTTP 协议的格式：

 

 request:

GET /index.jsp?username=xinchun.wang&password=123456 HTTP/1.1
Host:192.168.237.230
Connection: close
 
 
response:
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Set-Cookie: JSESSIONID=2D3FE2C8EA372E3ACC69C48E12348B44; Path=/
Content-Type: text/html;charset=ISO-8859-1
Content-Length: 288
Date: Tue, 25 Apr 2017 03:06:57 GMT
Connection: close









 xinchun.wang
  123456

  

  代码参考：

public class ClientGet {
	
	public static void main(String[] args) {
		sendRequest(8078);
	}
	
	public static void sendRequest(int port) {  
		  try {
			   Socket socket = new Socket("192.168.237.230", port);  
			  
			   OutputStream out = socket.getOutputStream();  
			  
			   // 由Socket对象得到输入流,并构造相应的BufferedReader对象  
			   BufferedReader in = new BufferedReader(new InputStreamReader(socket  
			     .getInputStream()));  
			  
			   StringBuilder sb = new StringBuilder();
			   sb.append("GET /index.jsp?username=xinchun.wang&password=123456 HTTP/1.1\r\n");
			   sb.append("Host:192.168.237.230\r\n");
			   sb.append("Connection: close\r\n");
			   sb.append("\r\n");
			   
			   out.write(sb.toString().getBytes());
			  
			   out.flush();
			   String line = in.readLine();
			   while(line != null &&  line.toString() != ""){
				   System.out.println(line);
				   line = in.readLine();
			   }
			   
			   out.close(); // 关闭Socket输出流  
			   in.close(); // 关闭Socket输入流  
			   socket.close(); // 关闭Socket  
			  
		  } catch (Exception e) {  
		   System.out.println("Error. " + e);  
		  }  
		 }  
}
