基于socketserver实现并发tcp、udp
1.基于socketserver实现并发-tcp
#服务端
import socketserver
class MyHandler(socketserver.BaseRequestHandler):
def handle(self):
#print(self.client_address) #客户端地址
#print(self.request) ##self.request=conn 套接字对象
while True:
try:
data = self.request.recv(1024)
if len(data) == 0: break
print()
self.request.send(data.upper())
except ConnectionResetError:
break
if __name__ == '__main__':
s = socketserver.ThreadingTCPServer(('127.0.0.1', 8080), MyHandler, bind_and_activate=True)
s.serve_forever() #代表连接循环
#循环建立连接,每建立一个连接就会启动一个线程+调用MyHandler类产生一个对象,
#该对象下面的handle方法,专门与刚刚建立好的连接做通信循环
#客户端地址
#print(self.request) ##self.request=conn 套接字对象
while True:
try:
data = self.request.recv(1024)
if len(data) == 0: break
print()
self.request.send(data.upper())
except ConnectionResetError:
break
if __name__ == '__main__':
s = socketserver.ThreadingTCPServer(('127.0.0.1', 8080), MyHandler, bind_and_activate=True)
s.serve_forever() #代表连接循环
#循环建立连接,每建立一个连接就会启动一个线程+调用MyHandler类产生一个对象,
#该对象下面的handle方法,专门与刚刚建立好的连接做通信循环
#客户端
import socket
phone=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
phone.connect(('127.0.0.1',8080))
while True:
msg=input(">>>>>>>>>>>>>").strip()
if len(msg)==0:continue
phone.send(msg.encode('utf-8'))
data=phone.recv(1024)
print(data)
phone.close()
1.基于socketserver实现并发-ucp
#服务端
import socketserver
class MyHandeler(socketserver.BaseRequestHandler):
def handle(self):
data = self.request[0] #request是个元组,元组的第一个是数据,第二个是一个套接字对象
print('消息', data)
self.request[1].sendto(data.upper(), self.client_address) #self.request[1] 是套接字对象
if __name__ == '__main__':
s = socketserver.ThreadingUDPServer(('127.0.0.1', 8080), MyHandeler)
s.serve_forever()
#request是个元组,元组的第一个是数据,第二个是一个套接字对象
print('消息', data)
self.request[1].sendto(data.upper(), self.client_address) #self.request[1] 是套接字对象
if __name__ == '__main__':
s = socketserver.ThreadingUDPServer(('127.0.0.1', 8080), MyHandeler)
s.serve_forever()
#客户端
import socket
client=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
while True:
msg=input('>>>>>>>').strip()
#msg='111111111111'
client.sendto(msg.encode('utf-8'),('127.0.0.1',8080))
data,server_addr=client.recvfrom(1024)
print(data)
client.close()
