消息后，套接字断开连接（远程主机拒绝连接），使用python

Question

I have uploaded my python socket, (cloud service project), on azure ,and when ever I connected to Hercules client side socket ....after a message or two, connection closed by remote host... forcefully...?

Server Code

from twisted.internet.protocol import Factory, Protocol
from twisted.internet import reactor
import SocketServer
class IphoneChat(Protocol):
    def connectionMade(self):
        self.factory.clients.append(self)
        print('clients are'), self.factory.clients                  
    def connectionLost(self, reason):
        self.factory.clients.remove(self)        
    def dataReceived(self, data):
        msg = ""
        msg =  data.strip()
        for c in self.factory.clients:
            c.message(msg)                  
    def message(self, message):
        self.transport.write(message + '\n')        

print ('Iphone Chat server startedd')
factory = Factory()
factory.protocol = IphoneChat
factory.clients = []
reactor.listenTCP(9073, factory)
reactor.run()

I tried to reproduce your issue on my environment, but failed. Base on my experience, we often pay attention to 3 points if we use socket in azure worker role.

1. Open input TCP port. If we open a port as listener port, we'd better to add this port into the endpoints setting.
   

2. Considered the worker role status, I suggest we can code logic into the while True loop function, as following,

    while True: reactor.listenTCP(65534, f) print "server run" reactor.run() sleep(1.0) 

3. According to the error message, I guess the reason is that azure load balancer will kill the idle connection in 240s. I recommend you can refer to this blog to configure your idleTimeoutInMinutes value.

Please try to check your project and configuration. Any further findings, please let me know.
