Amazon SNS到SQS-使用.NET SDK确认订阅

Question

我正在尝试设置Amazon Ses通知到我的SQS队列。我正在遵循如何创建SQS队列，然后是SNS主题，并将一个订阅到另一个。

但是，在管理控制台中，订阅出现“挂起确认”。

我使用的是.NET AWS SDK，如何确认订阅？或者更好，为什么我要确认？文件上说

    private static string CreateBounceTopicAndQueue(IAmazonSQS sqsClient, IAmazonSimpleNotificationService snsClient)
    {
        // 1. Create an Amazon SQS queue named ses-bounces-queue.
        CreateQueueResponse createQueueResponse = sqsClient.CreateQueue(new CreateQueueRequest()
        {
            QueueName = AppGlobal.SesBouncesQueue,
            Attributes = new Dictionary<string, string>() {
                { "ReceiveMessageWaitTimeSeconds", "20" }
            }
        });
        string queueUrl = createQueueResponse.QueueUrl;

        // 2. Create an Amazon SNS topic named ses-bounces-topic
        CreateTopicResponse createTopicResponse = snsClient.CreateTopic(new CreateTopicRequest
        {
            Name = AppGlobal.SesBouncesTopic
        });
        string topicArn = createTopicResponse.TopicArn;

        // 3. Configure the Amazon SNS topic to publish to the SQS queue
        var response =  snsClient.Subscribe(new SubscribeRequest
        {
            TopicArn = topicArn,
            Endpoint = queueUrl,
            Protocol = "https"
        });

        return queueUrl;
    }

Answer 1

您不需要通过使用队列URL创建https订阅来将SQS队列订阅到SNS主题。

您创建一个“SQS”（不是https）协议订阅，将队列的ARN（不是webendpoint）作为endpoint。

protocol
Type: System.String
The protocol you want to use. 
...
sqs -- delivery of JSON-encoded message to an Amazon SQS queue

endpoint
Type: System.String
The endpoint that you want to receive notifications. Endpoints vary by protocol...

For the sqs protocol, the endpoint is the ARN of an Amazon SQS queue
