12         Socket socket = new Socket(host, port);

14         BufferedWriter out = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
15         BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
16         
17         StringBuffer sb = new StringBuffer();
18         //请求的连接地址
19         sb.append("POST /ServletBindUrl HTTP/1.1\r\n")
20            .append("Host:"+ host + "\r\n")

22            .append("Content-Length:11\r\n")            //11 这个数值是看底下内容的长度的 即多少个字符
23            .append("\r\n")
24            .append("id=01234567\r\n");                  //内容

26         out.write(sb.toString());
27         out.flush();
28         
29         //打印响应
30         String line = "";
31         while((line = in.readLine()) != null)
32             System.out.println(line);
33     }
