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()
