用Python写的一个多线程TCP通信实例

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、客户端#!/usr/bin/env python# -*- coding:utf-8 -*-#import socketimport threadingimport SocketServerimport jsondef 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 socketimport threadingimport SocketServerimport json, types,stringimport 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):    passif __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()
