扭曲的AMP服務器未接收到數據

Question

我在twisted上構建了一個多服務守護程序，該守護程序從django接收命令，而這種情況是

1. django視圖連接amp服務器
2. DJango沒有發送命令或AMP沒有收到命令

我的問題是我在做什么錯

我的代碼是：

AMP服務器

from twisted.protocols.amp import AMP, Command, String

class AmpProcessor(Command):
    arguments = [('proto', String()),
                 ('imei', String()),
                 ('ip', String()),
                 ('port', String()),
                 ('cmmd', String())]
    response = [('answer', String())]

class AMPServer(AMP):


    @AmpProcessor.responder
    def processor(self, proto, imei, ip, port, cmmd):
        print cmmd
        self.factories['proto'].clients['ip'].sendMessage(cmmd)
        return {'answer': 'ok'}

for device in config.get('protocols', 'keys').split(','):
    devicer = config.get(device, 'name')
    factories[devicer] = TrackerFactory(devicer)
    internet.TCPServer(int(config.get(device, 'port')), factories[devicer]).setServiceParent(application)

endpoint = TCP4ServerEndpoint(reactor, 8750)
factory = Factory()
factory.protocol = AMPServer
factory.protocol.factories = factories
ampService = StreamServerEndpointService(endpoint, factory)
ampService.setServiceParent(application)

每個進程只能調用一次reactor.run 。 我猜您每個請求調用一次send_fence_to_device 。 這意味着它可能只工作一次，但是所有后續調用都將失敗。

如果您打算在Django應用程序中可靠地使用Twisted，那么Crochet可能會有所幫助。
