NonStop Server 試用Python

目標：使用python 開發Client/Server Thread program
測試結果：Nonstop server 不支援 Thread，只能使用 fork 。
Client 程式：

Server 程式：

import SocketServer,time
myHost=''
myPort=12343

class MyClientHandler(SocketServer.BaseRequestHandler):
   def handle(self):
       print 'Welcome Clinet:',self.client_address
       while True:
           data=self.request.recv(1024)
           time.sleep(1)
           if not data:break
           print 'Send Back:',data
           self.request.send(data)           
       self.request.close()


myaddr=(myHost,myPort)
server=SocketServer.ThreadingTCPServer(myaddr,MyClientHandler)
server.serve_forever()
