python怎样建立socket服务器

Answer 1

下面的例子是多线程实现的socket服务器：

import socketimport threadingclass ThreadedServer(object):
def __init__(self, host, port):
self.host = host
self.port = port
self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
self.sock.bind((self.host, self.port))

def listen(self):
self.sock.listen(5)
while True:
client, address = self.sock.accept()
client.settimeout(60)
threading.Thread(target = self.listenToClient,args = (client,address)).start()

def listenToClient(self, client, address):
size = 1024
while True:
try:
data = client.recv(size)
if data:
# Set the response to echo back the recieved data
response = data
client.send(response)
else:
raise error('Client disconnected')
except:
client.close()
return Falseif __name__ == "__main__":
while True:
port_num = input("Port? ")
try:
port_num = int(port_num)
break
except ValueError:
pass

ThreadedServer('',port_num).listen()
