socketserver.TCPServer Example

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

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)
