socketserver實現多使用者連線簡單程式碼

1.服務端

import socketserver

class MyTCPHandler(socketserver.BaseRequestHandler):
    def handle(self):
        while True:
            try:
                self.data = self.request.recv(1024).strip()
                print("{} wrote".format(self.client_address[0]))
                print(self.data)
                self.request.send(self.data.upper())
            except ConnectionResetError as e:
                print("error", e)
                break

if __name__=="__main__":
    HOST, PORT = "0.0.0.0", 22222
    server = socketserver.ThreadingTCPServer((HOST, PORT), MyTCPHandler)

    server.serve_forever()

2.客戶端

import socket
client = socket.socket()  
client.connect(("localhost", 22222))

while True:
    msg = input(">>:").strip()
    if len(msg) == 0:continue
    client.send(msg.encode("utf-8"))
    data = client.recv(1024)
    print( data.decode())
client.close()
