【问题描述】:
我正在尝试使用此代码将 iOS 端点订阅到 SNS 主题:
let sns = AWSSNS.defaultSNS()
let request = AWSSNSCreatePlatformEndpointInput()
request.token = deviceTokenString
request.platformApplicationArn = SNSPlatformApplicationArn
sns.createPlatformEndpoint(request).continueWithExecutor(AWSExecutor.mainThreadExecutor(), withBlock: { (task: AWSTask!) -> AnyObject! in
if task.error != nil {
print(task.error)
} else {
let createEndpointResponse = task.result as! AWSSNSCreateEndpointResponse
// Subscribe to the topic
let subscribeTopicInput = AWSSNSSubscribeInput()
subscribeTopicInput.endpoint = createEndpointResponse.endpointArn
subscribeTopicInput.protocols = "application"
subscribeTopicInput.topicArn = MyTopicARN
sns.subscribe(subscribeTopicInput).continueWithExecutor(AWSExecutor.mainThreadExecutor(), withBlock: { (topicTask: AWSTask!) -> AnyObject! in
if topicTask.error != nil {
// Authorization error prints here
print(topicTask.error)
}
return nil
})
}
return nil
})
尝试订阅主题时收到错误消息:
UserInfo={Type=Sender, Message=User: arn:aws:its::000000000000:assumed-role/appname_unauth_MOBILEHUB_000000000/CognitoIdentityCredentials is not authorized to perform: SNS:Subscribe on resource:...
this answer 的作者解释说,您必须在您的 Cognito 角色中授予对 sns:Subscribe 的访问权限,才能允许您的应用程序进行此调用。我的 Cognito 用户已被授予 AmazonSNSFullAccess,它允许访问所有 sns 操作(例如 sns:*)。为什么我的 Cognito 用户被拒绝访问?我的主题策略设置为只有主题所有者可以订阅...但主题所有者似乎与我的 Cognito 用户相同。
