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-*-
__author__ = "MuT6 Sch01aR"
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
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()
