python实现的基于TCP的JSON数据通信

浏览数：13 / 时间：2015年06月08日

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 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()
