本文介绍了一项跨语言客户端/服务器（C/S）Socket通讯的实验，使用Java实现服务器端，Python实现客户端。实验中详细展示了如何通过不同语言进行Socket连接、数据发送与接收的过程，并特别指出在Python客户端发送数据时需要添加来标识数据结束。

今天做了一个不同语言之间 C/S 的socket通讯实验, 还是发现了在不同语言间的问题. :)

服务器端

package p1;

import java.io.IOException;
import java.net.ServerSocket;

public class C1 {

private ServerSocket ss;

public C1() {
  try {
   int i = 0;
   ss = new ServerSocket(10000);
   while (true) {
    i++;
    T t = new T(ss.accept(), i);
    Thread tt = new Thread(t);
    tt.start();

}

  } catch (IOException e) {
   e.printStackTrace();
  }finally{
   if(ss != null){
    try {
     ss.close();
    } catch (IOException e) {
     e.printStackTrace();
    }
   }
  }
}

public static void main(String[] args) {
new C1();
}

}

package p1;

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

public class T implements Runnable {

private Socket socket;
private BufferedReader in;
private PrintWriter out;
private int i = 0;

public T(Socket socket, int i){
  this.socket = socket;
  this.i = i;
}

@Override
public void run() {
  try {
  in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
   in.readLine();
   System.out.println(i + " Server Socket sleep 1 sec");
   Thread.sleep(1000);

   out = new PrintWriter(socket.getOutputStream());
   out.write("this is " + i + " echo ");
   out.flush();
   socket.close();
  } catch (Exception e) {
   e.printStackTrace();
  }

}

public void setSocket(Socket socket) {
this.socket = socket;
}

public Socket getSocket() {
return socket;
}

}

客户端: (注意send时, 后面要显示加一个 \r 来告诉java的socket:"数据发送完毕", 否则会一直在in.readLine()等待)

import time

class timer(threading.Thread):

    def __init__(self, i):
        threading.Thread.__init__(self)
        self.i = i

def run(self):

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(('192.168.2.49', 10000))

        print "connected";
        sock.send(time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time())) + "\r")
        print "send data...";
        sock.recv(1024);
        print "recv data...";
        sock.close()

def test():
     n = int(raw_input("please input loop count"));
     for i in range(1, n + 1):
            t1=timer(i)
            t1.start()

if __name__=='__main__':

test()
