Socket网络编程二

SocketServer

socketserver一共有这么几种类型

class socketserver.TCPServer(server_address, RequestHandlerClass, bind_and_activate=True)

class socketserver.UDPServer(server_address, RequestHandlerClass, bind_and_activate=True)

class socketserver.UnixStreamServer(server_address, RequestHandlerClass, bind_and_activate=True)
class socketserver.UnixDatagramServer(server_address, RequestHandlerClass,bind_and_activate=True)

让你的socketserver并发起来， 必须选择使用以下一个多并发的类

class socketserver.ForkingTCPServer

class socketserver.ForkingUDPServer

class socketserver.ThreadingTCPServer

class socketserver.ThreadingUDPServer

用ThreadingTCPServer实现多线程并发。

import socketserver

class MyTCPHandler(socketserver.BaseRequestHandler):
    def handle(self):
        while True:
            self.data = self.request.recv(1024).strip()
            print("{} wrote:".format(self.client_address[0]))
            print(self.data)
            self.request.sendall(self.data.upper())

if __name__ == "__main__":
    HOST, PORT = "localhost", 9999
    server = socketserver.ThreadingTCPServer((HOST, PORT), MyTCPHandler)
    server.serve_forever()

以上代码运行结果

import socket

client= socket.socket()
client.connect((‘localhost‘,9999))
while True:
    choice=input(‘>>:‘).strip()
    if len(choice)==0:continue
    client.send(choice.encode())
    recv=client.recv(1024)
    print(‘recv data:‘,recv)
