python-- socketServer

本文主要是介绍python-- socketServer，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

socketServer

客户端

import socket

client = socket.socket()
client.connect(('localhost', 9999))
while True:
    msg = input('>>>>:').strip()
    if len(msg) == 0:
        continue
    client.send(msg.encode('utf-8'))
    data = client.recv(1024)
    print("recv:", data.decode())

client.close()

服务端

import socketserver


class MyTcpHandler(socketserver.BaseRequestHandler):
    def handle(self):
        while True:
            try:
                self.data = self.request.recv(1024).strip()
                print("{} wrote:".format(self.client_address[0]))
                print(self.data)
                self.request.send(self.data.upper())
            except ConnectionResetError as e:
                print('err', e)
                break


if __name__ == "__main__":
    HOST, PORT = 'localhost', 9999
    server = socketserver.TCPServer((HOST, PORT), MyTcpHandler)
    server.serve_forever()

socketServer 多并发

客户端

import socket

client = socket.socket()
client.connect(('localhost', 9999))
while True:
    msg = input('>>>>:').strip()
    if len(msg) == 0:
        continue
    client.send(msg.encode('utf-8'))
    data = client.recv(1024)
    print("recv:", data.decode())

client.close()

服务端

import socketserver


class MyTcpHandler(socketserver.BaseRequestHandler):
    def handle(self):
        while True:
            try:
                self.data = self.request.recv(1024).strip()
                print("{} wrote:".format(self.client_address[0]))
                print(self.data)
                self.request.send(self.data.upper())
            except ConnectionResetError as e:
                print('err', e)
                break


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

可以同时处理多个客户端
