15.使用socketServer模块实现并发

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
    # s=socketserver.ForkingTCPServer(('127.0.0.1',8080),MyServer) #多进程

    # self.server_address = server_address
    # self.RequestHandlerClass = RequestHandlerClass
    print(s.server_address)
    print(s.RequestHandlerClass)
    print(MyServer)
    print(s.socket)
    print(s.server_address)
    s.serve_forever()
