扭曲的AMP服务器未接收到数据

Question

我在twisted上构建了一个多服务守护程序，该守护程序从django接收命令，而这种情况是

1. django视图连接amp服务器
2. DJango没有发送命令或AMP没有收到命令

我的问题是我在做什么错

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'}

TAC文件

import os, sys
import ConfigParser
from twisted.application import internet, service
from twisted.internet import protocol, reactor
from listener.TrackerServer import TrackerFactory
from listener.AMPServer import AMPServer
from twisted.internet.protocol import Factory
from twisted.internet.endpoints import TCP4ServerEndpoint
from twisted.application.internet import StreamServerEndpointService

PROJECT_DIR = os.path.abspath(os.path.dirname(__file__))
sys.path.append(PROJECT_DIR)

path = None
config = ConfigParser.ConfigParser()
config.read('protocols.cfg')

application = service.Application("tracker")

factories = {}

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)

Django视图

def send_fence_to_device (request):
    device_fence_id = request.GET['device_fence_id']
    device_id = request.GET['device_id']
    fence_id = request.GET['fence_id']
    fnc = Fence.objects.get(id=fence_id)
    dev = Device.objects.get(id=device_id)
    try:
        devLog = dev.devicelog_set.filter(device_id=device_id, status = True).order_by('created').reverse()[:1].all()[0]
        params = simplejson.loads(fnc.other)
        lttdlgtd = simplejson.loads(fnc.points)
        strCommand = ".geo.%s,%s,%s,%s,%s,%s,%s,%s,%s" % (params['identificator'], fnc.name[:4], round(float(lttdlgtd[0][0]), 4), round(float(lttdlgtd[0][1]), 4), round(float(fnc.radius), 4), params['time_to_arrive'], params['fence_class'], params['tolerance'], 1)
        d = connect()
        def connected(protocol):
            return protocol.callRemote(
                AmpProcessor,
                proto='TELCOMIP',
                imei=devLog.ip,
                ip=devLog.ip,
                port=devLog.port,
                command=strCommand)
        d.addCallback(connected)

        def saved(result):
            return HttpResponse(simplejson.dumps(result), mimetype='application/json')
            #print 'Registration result:', result
        d.addCallback(saved)
        #d.addErrback(err, "Failed to register")

        def finished(ignored):
            reactor.stop()
        d.addCallback(finished)
        reactor.run(installSignalHandlers=0)

        #return HttpResponse(simplejson.dumps(1), mimetype='application/json')
    except:
        return HttpResponse(simplejson.dumps(0), mimetype='application/json')



def connect():
    endpoint = TCP4ClientEndpoint(reactor, "127.0.0.1", 8750)
    factory = Factory()
    factory.protocol = AMP
    return endpoint.connect(factory)


class DeviceUnavailable(Exception):
    pass

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

    response = [('answer', String())]

    errors = {DeviceUnavailable: 'device-unavailable'}

Answer 1

每个进程只能调用一次reactor.run 。 我猜您每个请求调用一次send_fence_to_device 。 这意味着它可能只工作一次，但是所有后续调用都将失败。

如果您打算在Django应用程序中可靠地使用Twisted，那么Crochet可能会有所帮助。
