Python中基于socketserver实现并发的socket

1、基于TCP协议：

服务端：

 import socketserver

 class MyHandler(socketserver.BaseRequestHandler):
     def handle(self):
         #通信循环
         while True:
             # print(self.client_address)
             # print(self.request) #self.request=conn

             try:
                 data=self.request.recv(1024)
                 if len(data) == 0:break
                 self.request.send(data.upper())
             except ConnectionResetError:
                 break

 if __name__ == '__main__':
     s=socketserver.ThreadingTCPServer(('127.0.0.1',8080),MyHandler,bind_and_activate=True)

     s.serve_forever()  # 代表连接循环
     # 循环建立连接，每建立一个连接就会启动一个线程（服务员）+调用Myhanlder类产生一个对象，调用该对象下的handle方法，专门与刚刚建立好的连接做通信循环

客户端：

 import socket

 phone=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
 phone.connect(('127.0.0.1',8080)) # 指定服务端ip和端口

 while True:
     # msg=input('>>: ').strip() #msg=''
     msg = 'client33333'  # msg=''
     if len(msg) == 0:continue
     phone.send(msg.encode('utf-8'))
     data=phone.recv(1024)
     print(data)

 phone.close()

2、基于UDP协议：

服务端：

 import socketserver

 class MyHandler(socketserver.BaseRequestHandler):
     def handle(self):
         #通信循环
         # print(self.client_address)
         # print(self.request)

         data=self.request[0]
         print('客户消息',data)
         self.request[1].sendto(data.upper(),self.client_address)

 if __name__ == '__main__':
     s=socketserver.ThreadingUDPServer(('127.0.0.1',8080),MyHandler)
     s.serve_forever()

客户端：

 import socket

 client=socket.socket(socket.AF_INET,socket.SOCK_DGRAM) #数据报协议-》udp

 while True:
     # msg=input('>>: ').strip() #msg=''
     msg='client444444'

     client.sendto(msg.encode('utf-8'),('127.0.0.1',8080))
     data,server_addr=client.recvfrom(1024)
     print(data)

 client.close()
