python实现的基于TCP的JSON数据通信

用Python写的一个多线程TCP通信实例，实现了JSON数据的传输。

闲言少述，直接上代码

​

一、client

#!/usr/bin/env python

# -*- coding:utf-8 -*-

#



import socket

import threading

import SocketServer

import json



def client(ip, port, message):

    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    sock.connect((ip, port))



    try:

        print "Send: {}".format(message)

        sock.sendall(message)

        response = sock.recv(1024)

        jresp = json.loads(response)

        print "Recv: ",jresp



    finally:

        sock.close()



if __name__ == "__main__":

    # Port 0 means to select an arbitrary unused port

    HOST, PORT = "localhost", 50001

    msg1 = [{'src':"zj", 'dst':"zjdst"}]

    msg2 = [{'src':"ln", 'dst':"lndst"}]

    msg3 = [{'src':"xj", 'dst':"xjdst"}]

​

    jmsg1 = json.dumps(msg1)

    jmsg2 = json.dumps(msg2)

    jmsg3 = json.dumps(msg3)



    client(HOST, PORT, jmsg1)

    client(HOST, PORT, jmsg2)

    client(HOST, PORT, jmsg3)



二、服务端

#!/usr/bin/env python

# -*- coding:utf-8 -*-

#



import socket

import threading

import SocketServer

import json, types,string

import os, time

  

class ThreadedTCPRequestHandler(SocketServer.BaseRequestHandler):

    def handle(self):

        data = self.request.recv(1024)

        jdata = json.loads(data)

        print "Receive data from '%r'"% (data)

        print "Receive jdata from '%r'"% (jdata)

        rec_src = jdata[0]['src']

        rec_dst = jdata[0]['dst']



        cur_thread = threading.current_thread()

        response = [{'thread':cur_thread.name,'src':rec_src,'dst':rec_dst}]



        jresp = json.dumps(response)

        self.request.sendall(jresp)

        rec_cmd = "proccess "+rec_src+" -o "+rec_dst

        print "CMD '%r'" % (rec_cmd)

        os.system(rec_cmd)

           

class ThreadedTCPServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):

    pass



if __name__ == "__main__":

    # Port 0 means to select an arbitrary unused port

    HOST, PORT = "localhost", 50001

    

    SocketServer.TCPServer.allow_reuse_address = True

    server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)

    ip, port = server.server_address



    # Start a thread with the server -- that thread will then start one

    # more thread for each request

    server_thread = threading.Thread(target=server.serve_forever)

​

    # Exit the server thread when the main thread terminates

    server_thread.daemon = True

    server_thread.start()

    print "Server loop running in thread:", server_thread.name

    print " .... waiting for connection"



    # Activate the server; this will keep running until you

    # interrupt the program with Ctrl-C

    server.serve_forever()
