Django + pyamf：从actionscript应用程序调用网关时出现奇怪的异常

Question

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

我定义的网关是这样的：

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]) 

当我打电话从MXML服务是这样的：

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

无论是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“状态”到“更新”的更改。
