socketserver 并发连接

socketserver.TCPServer Example

server side

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

import  socketserver   class  MyTCPHandler(socketserver.BaseRequestHandler):      """      The request handler class for our server.        It is instantiated once per connection to the server, and must      override the handle() method to implement communication to the      client.      """        def  handle( self ):          # self.request is the TCP socket connected to the client          self .data  =  self .request.recv( 1024 ).strip()          print ( "{} wrote:" . format ( self .client_address[ 0 ]))          print ( self .data)          # just send back the same data, but upper-cased          self .request.sendall( self .data.upper())   if  __name__  = =  "__main__" :      HOST, PORT  =  "localhost" ,  9999        # Create the server, binding to localhost on port 9999      server  =  socketserver.TCPServer((HOST, PORT), MyTCPHandler)        # Activate the server; this will keep running until you      # interrupt the program with Ctrl-C      server.serve_forever()

client side

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

import  socket import  sys   HOST, PORT  =  "localhost" ,  9999 data  =  " " .join(sys.argv[ 1 :])   # Create a socket (SOCK_STREAM means a TCP socket) sock  =  socket.socket(socket.AF_INET, socket.SOCK_STREAM)   try :      # Connect to server and send data      sock.connect((HOST, PORT))      sock.sendall(bytes(data  +  "\n" ,  "utf-8" ))        # Receive data from the server and shut down      received  =  str (sock.recv( 1024 ),  "utf-8" ) finally :      sock.close()   print ( "Sent:     {}" . format (data)) print ( "Received: {}" . format (received))

上面这个例子你会发现，依然不能实现多并发，哈哈，在server端做一下更改就可以了

把

1	server  =  socketserver.TCPServer((HOST, PORT), MyTCPHandler)

改成

1	server  =  socketserver.ThreadingTCPServer((HOST, PORT), MyTCPHandler)
