利用Python中SocketServer实现客户端与服务器间非阻塞通信方法介绍

#创建SocketServerTCP服务器：  
import SocketServer  
from SocketServer import StreamRequestHandler as SRH  
from time import ctime  
  
host = 'xxx.xxx.xxx.xxx'  
port = 9999  
addr = (host,port)  
  
class Servers(SRH):  
    def handle(self):  
        print 'got connection from ',self.client_address  
        self.wfile.write('connection %s:%s at %s succeed!' % (host,port,ctime()))  
        while True:  
            data = self.request.recv(1024)  
            if not data:   
                break  
            print data  
            print "RECV from ", self.client_address[0]  
            self.request.send(data)  
print 'server is running....'  
server = SocketServer.ThreadingTCPServer(addr,Servers)  
server.serve_forever()

#from socket
from socket import *  
  
host = 'xxx.xxx.xxx.xxx'  
port = 9999  
bufsize = 1024  
addr = (host,port)  
#client = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client = socket(AF_INET,SOCK_STREAM)  
client.connect(addr)  
while True:  
    data = raw_input()  
    if not data or data=='exit':  
        break  
    client.send('%s\r\n' % data)  
    data = client.recv(bufsize)  
    if not data:  
        break  
    print data.strip()  
client.close()
