socketserver模块(实现并发)
一、基于UDP协议实现的并发
# 服务端
import socketserver
class MyServer(socketserver.BaseRequestHandler):
def handle(self):
# print('来啦 老弟')
while True:
data,sock = self.request
print(self.client_address) # 客户端地址
print(data.decode('utf-8'))
sock.sendto(data.upper(),self.client_address)
if __name__ == '__main__':
"""只要有客户端连接 会自动交给自定义类中的handle方法去处理"""
server = socketserver.ThreadingUDPServer(('127.0.0.1',8080),MyServer) # 创建一个基于UDP的对象
server.serve_forever() # 启动该服务对象
# 客户端
import socket
import time
client = socket.socket(type=socket.SOCK_DGRAM)
server_address = ('127.0.0.1',8080)
while True:
client.sendto(b'hello',server_address)
data,addr = client.recvfrom(1024)
print(data.decode('utf-8'),addr)
time.sleep(1) # 发送间隔太短的话,看不出效果
二、基于TCP协议实现的并发
# 服务端
import socketserver
class MyServer(socketserver.BaseRequestHandler):
def handle(self):
# print('来啦 老弟')
while True:
data = self.request.recv(1024)
print(self.client_address) # 客户端地址
print(data.decode('utf-8'))
self.request.send(data.upper())
if __name__ == '__main__':
"""只要有客户端连接 会自动交给自定义类中的handle方法去处理"""
server = socketserver.ThreadingTCPServer(('127.0.0.1',8080),MyServer) # 创建一个基于TCP的对象
server.serve_forever() # 启动该服务对象
# 客户端
import socket
client = socket.socket()
client.connect(('127.0.0.1',8080))
while True:
client.send(b'hello')
data = client.recv(1024)
print(data.decode('utf-8'))
