python_网络编程socketserver模块实现多用户通信

服务端：

import socketserver

class MyServer(socketserver.BaseRequestHandler):
    def handle(self):   #在这个函数里面编写发送和接收的语句，方法名必须为handle

        self.request.sendall('请输入内容：'.encode('utf-8'))  #向所有连接的客户端发送消息
        while True:
            msg = self.request.recv(1024).decode('utf-8')
            if msg == 'q':
                break
            print(msg)
            info = input('>>>')
            self.request.send(info.encode('utf-8'))

if __name__ == '__main__':
    server = socketserver.ThreadingTCPServer(('127.0.0.1',8080),MyServer)   #设置服务器地址和端口号
    server.serve_forever()      #持续与客户端通信

客户端1：

import socket
sk = socket.socket()
sk.connect(('127.0.0.1',8080))

qqq = sk.recv(1024)
print(qqq.decode('utf-8'))

while True:
    msg = input('>>>')
    if msg == 'q':
        sk.send(b'q')
        break
    sk.send(('王佃超：{}'.format(msg)).encode('utf-8'))
    ret = sk.recv(1024).decode('utf-8')
    print(ret)

sk.close()

客户端2：

import socket
sk = socket.socket()
sk.connect(('127.0.0.1',8080))

qqq = sk.recv(1024)
print(qqq.decode('utf-8'))

while True:
    msg = input('>>>')
    if msg == 'q':
        sk.send(b'q')
        break
    sk.send(('尹洪飞：{}'.format(msg)).encode('utf-8'))
    ret = sk.recv(1024).decode('utf-8')
    print(ret)

sk.close()
