订阅确认时 Amazon SNS SDK 无效参数异常 [英] Amazon SNS SDK Invalid Parameter exception on subscription confirmation

问题描述

我正在尝试使用此代码订阅 Android 用户以接收推送通知:

I'm trying to subscribe an Android user to receive push notifications using this code:

 public static void subscribeToTopic(final String topicArn, String EndpointArn) {
        SubscribeRequest request = new SubscribeRequest(topicArn, "application" , EndpointArn);
        SubscribeResult response = getInstance().subscribe(request);
        ConfirmSubscriptionRequest confirmation = new ConfirmSubscriptionRequest(topicArn, response.getSubscriptionArn());
        try {
            getInstance().confirmSubscription(confirmation);
        } catch (Exception e) {
            Log.d(TAG, "UNEXPECTED EXCEPTION: " + e);
        }
    }

但是，我在 confirmSubscription() 上得到以下异常:

However, I get the following exception on confirmSubscription():

10-15 15:39:59.453:D/(31274):意外异常:com.amazonaws.services.sns.model.InvalidParameterException:无效令牌(服务:AmazonSNS；状态代码:400；错误代码:无效的参数;请求 ID:742123aa-6dce-52f2-b2de-6f127516ec56)

10-15 15:39:59.453: D/(31274): UNEXPECTED EXCEPTION: com.amazonaws.services.sns.model.InvalidParameterException: Invalid token (Service: AmazonSNS; Status Code: 400; Error Code: InvalidParameter; Request ID: 742123aa-6dce-52f2-b2de-6f127516ec56)

然而，订阅成功，我成功向应用发送推送通知.

However, the subscription IS a success and I succeeded to send push notifications to the app.

知道为什么我会收到这个错误吗?是因为这个协议不需要确认吗?

Any idea why I get this error ? Is it because confirmation is unnecessary on for this protocol ?

推荐答案

Android 端点(和所有移动端点)在 Subscribe 完成时自动确认.您不需要为这些端点调用 ConfirmSubscription.

Android endpoints (and all mobile endpoints) are automatically confirmed when Subscribe completes. You do not need to invoke ConfirmSubscription for these endpoints.
