`socketserver.TCPServer` Example

server side

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 + "
", "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)`
