AWS SNS错误无效参数:令牌原因:端点xxx已存在,具有相同的令牌,但属性不同

Question

使用适用于iOS的AWS SDK v2.0.8

快速提问:

我如何[snsClient deleteEndpoint:request],我不知道这个端点的阿尔恩？我确实有deviceToken.

详情:

我Token Reason: Endpoint arn:aws:sns:...c6 already exists with the same Token, but different attributes尝试为iPhone创建端点时收到错误:

// Async call to create the platform endpoint
[[[_awsSnsClient createPlatformEndpoint:request] continueWithSuccessBlock:^id(BFTask *task) {
    // success
    _awsPlatformEndpoint = task.result; // Save off the endpoint data
    [self awsUsubscribeAllSubscriptions];
    return nil;
}] continueWithBlock:^id(BFTask *task) {
    if (task.error) {
        // failed with error
        ALog(@"Error: Code:%li localizedDesc:%@ Exception:%@", (long)task.error.code, task.error.localizedDescription, task.exception);
        if(task.error.code == 7) {
            // delete offending endpoint and create it again?
        }
    }
    return nil;
}];

当我创建端点时,我没有设置attributes,我customUserData根据可以更改的客户端数据进行设置.在它的SDK文档中customUserData说:与端点关联的任意用户数据.Amazon SNS不使用此数据.数据必须采用UTF-8格式且小于2KB.

当我从SNS控制台删除端点时,我可以获得一个新端点.那么当我不知道这个端点的arn时,如何deleteEndpoint呢？我可以在AWS日志记录中看到arn,但不能在BFTask*错误对象中看到.

我在19551067看到了ruby解决方案,但是我没有看到读取消息的方法,ruby示例从异常中读取消息,在我的情况下是task.exception == nil.我从AWS详细日志中收到:

使用AWS日志记录:

2014-10-01 06:48:54.489 myApp[1665:1345740] AWSiOSSDKv2 [Verbose] AWSURLResponseSerialization.m line:244 | -[AWSXMLResponseSerializer responseObjectForResponse:originalRequest:currentRequest:data:error:] | Response body: [<ErrorResponse xmlns="http://sns.amazonaws.com/doc/2010-03-31/">

  </Error>
  <RequestId>d874ac10-e6de-5a4d-805e-e0b6ee58e5b7</RequestId>
</ErrorResponse>
]

我可以得到什么(BFTask*任务).error:

2014-10-01 06:48:54.494 myApp[1665:1345740] __46-[AppDelegate_Shared awsStartWithDeviceToken:]_block_invoke1279 [Line 3558] Error: 
  Code:7 
  localizedDesc:The operation couldn’t be completed. (com.amazonaws.AWSSNSErrorDomain error 7.)
  Exception:(null)

**更新2014-10-01**

我的开发iPad在更新到iOS 8.0.2后才开始这样做.我确实将版本号添加到customUserData- 但亚马逊SNS不使用此字段......对吗？

**更新2014-01-01 19:06 GMT-07:00**

添加task.error.userInfo到错误块.我会解析消息并在出现时删除端点.一个AWSSNSCreatePlatformEndpointInput覆盖此错误的选项,更新端点并返回端点将是不错的;)

谢谢!

控制台现在有:
