我在 twisted 上构建了一个多服务守护程序,它从 django 接收命令,发生的情况是
- django视图连接amp服务器
- DJango 未发送命令或 AMP 未收到命令
我的问题是我做错了什么
我的代码是:
AMP 服务器
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'}

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