Python学习之socketserver

 

利用socketserver实现并发tcp：

#利用socketserver实现并发：
服务端：
import socketserver

class MyServer(socketserver.BaseRequestHandler):

    def handle(self):
        print('conn is: ',self.request)   #conn
        print('addr is: ',self.client_address) #addr

        while True:
            try:
            #收消息
                data=self.request.recv(1024)
                if not data:break
                print('收到客户端的消息是',data,self.client_address)

                #发消息
                self.request.sendall(data.upper())

            except Exception as e:
                print(e)
                break

if __name__ == '__main__':
    s=socketserver.ThreadingTCPServer(('127.0.0.1',8080),MyServer) #多线程的tcp服务端
    # s=socketserver.ForkingTCPServer(('127.0.0.1',8080),MyServer) #多进程
客户端：
from socket import *
ip_port=('127.0.0.1',8080)
back_log=5
buffer_size=1024
tcp_client=socket(AF_INET,SOCK_STREAM)
tcp_client.connect(ip_port)
while True:
    msg=input('>>: ').strip()
    if not msg:continue
    if msg == 'quit':break
    tcp_client.send(msg.encode('utf-8'))
    data=tcp_client.recv(buffer_size)
    print('收到服务端发来的消息：',data.decode('utf-8'))

tcp_client.close()
