Python-SocketServer

Posted 2020-10-24 Sch01aR#

建立一个SocketServer，首先要创建一个请求处理类，这个类要继承BaseRequestHandler，还要重写父类里handle()方法，handle()方法在父类中为空的

然后实例化TCPServer，并且传递server ip和创建的请求处理类给这个TCPServer

服务器端

# -*-coding:utf-8-*-

import socketserver,socket

class MyTCPHandler(socketserver.BaseRequestHandler): #创建请求处理类，继承BaseRequestHandler
    def handle(self): #重写父类里handle()方法
        while True:
            try:
              self.data = self.request.recv(1024).strip()
              print(\'来自\',self.client_address[0])
              print(self.data)
              self.request.send(self.data)
            except socket.error:
                print(\'客户端断开连接\')
                break

if __name__ == "__main__":
    HOST, PORT = "localhost", 9999
    server = socketserver.TCPServer((HOST, PORT), MyTCPHandler) #实例化TCPServer
    # server = socketserver.UDPServer((HOST, PORT), MyTCPHandler) #实例化UDPServer
    server.serve_forever() #处理多个请求，一直执行
    # servser.handle_request() #只处理一个请求

客户端

# -*- coding:utf-8 -*-
__author__ = "MuT6 Sch01aR"

import socket

s = socket.socket()
s.connect((\'localhost\', 9999))
while True:
    cmd = input(\'>>>:\').strip()
    if len(cmd) == 0:continue
    s.send(cmd.encode(\'utf-8\'))
    print(s.recv(1024))
s.close()

运行结果

但是还是不能实现多个连接进行socket通信

socketserver多并发

服务器端

# -*-coding:utf-8-*-
__author__ = "MuT6 Sch01aR"

import socketserver,socket

class MyTCPHandler(socketserver.BaseRequestHandler):
    def handle(self):
        while True:
            try:
              self.data = self.request.recv(1024).strip()
              print(\'来自\',self.client_address[0])
              print(self.data)
              self.request.send(self.data)
            except socket.error:
                print(\'客户端断开连接\')
                break

if __name__ == "__main__":
    HOST, PORT = "localhost", 9999
    server = socketserver.ThreadingTCPServer((HOST, PORT), MyTCPHandler) #通过多线程实现TCPServer多并发
    #server = socketserver.ForkingTCPServer((HOST, PORT), MyTCPHandler) #通过多进程实现TCPServer多并发
    #server = socketserver.ThreadingUDPServer((HOST, PORT), MyTCPHandler) #通过多线程实现UDPServer多并发
    #server = socketserver.ForkingUDPServer((HOST, PORT), MyTCPHandler) #通过多线程实现UDPServer多并发
    server.serve_forever()

windows系统还不能用多进程进行socketserver多并发

s = socket.socket()
s.connect((\'localhost\', 9999))
while True:
    cmd = input(\'>>>:\').strip()
    if len(cmd) == 0:continue
    s.send(cmd.encode(\'utf-8\'))
    print(s.recv(1024))
s.close()
