python之socketserver ftp功能简单讲解

TCP协议中的socket一次只能和一个客户端通信，然而socketserver可以实现和多个客户端通信。

它是在socket的基础上进行了一层封装，底层还是调用的socket

# 服务端
import  socketserver
class Myserver(socketserver.BaseRequestHandler):

    def  handle(self):
        while 1:
            from_client_msg = self.request.recv(1024)
            print(from_client_msg.decode('utf-8'))
            msg = input('服务器说:')
            self.request.send(msg.encode('utf-8'))

if __name__ == '__main__':
    ip_port = ('127.0.0.1', 8001)
    server = socketserver.ThreadingTCPServer(ip_port, Myserver)
    server.serve_forever()

# 客户端
import socket
client = socket.socket()
client.connect(('127.0.0.1', 8001))
while 1:
    msg = input('客户端说:')
    client.send(msg.encode('utf-8'))
    from_server_msg = client.recv(1024)
    print(from_server_msg.decode('utf-8'))
