Question

你能帮忙吗？我正在使用django-amf-gateway应用程序（http://bitbucket.org/wolever/django-amf-gateway）。

我用这种方式定义了网关：

from django_amf_gateway import register_amf_service
from goserver.models import Game

class ChangeService(object):
    def state(self):
        game = Game.objects.get(id = 1)
        return game.move_number


register_amf_service('state', ChangeService, [Game])

当我以这种方式从mxml调用服务时：

updateService.state();

<mx:RemoteObject id="updateService" endpoint="{Config.updateGateWay}" destination="state">
    <mx:method name="update" result="onSuccess(event)" fault="onFault(event)" />
</mx:RemoteObject>

我有一个例外：

> [RPC Fault
> faultString="[MessagingError
> message='Destination 'state' either
> does not exist or the destination has
> no channels defined (and the
> application does not define any
> default channels.)']"
> faultCode="InvokeFailed"
> faultDetail="Couldn't establish a
> connection to 'state'"]   at

Answer 1

mx：RemoteObject方法名称错误或需要更新Python代码：

class ChangeService(object):
    def update(self):
        game = Game.objects.get(id = 1)
        return game.move_number

请注意从“州”更改为“更新”。
