AWS SNS服務SMS取消訂閱

Question

我正在使用AWS SNS服務將警報消息發送給用戶phone.However用戶取消訂閱該主題仍然他從該主題獲取消息。停止獲取消息用戶發送消息STOP .Following用於創建和訂閱主題的代碼片段。

CreateTopicRequest createTopicRequest = new CreateTopicRequest(topicName); 
CreateTopicResult createTopicResult = snsClient.createTopic(createTopicRequest); 

//Topic display name 
SetTopicAttributesRequest setTopicAttributesRequest = new SetTopicAttributesRequest(); 
setTopicAttributesRequest.withTopicArn(createTopicResult.getTopicArn()); 
setTopicAttributesRequest.setAttributeName(topicAttributeName); 
setTopicAttributesRequest.setAttributeValue(topicAttributeValue); 
snsClient.setTopicAttributes(setTopicAttributesRequest); 

SubscribeRequest subRequest = new SubscribeRequest(createTopicResult.getTopicArn(), "sms","12712438216"); 
snsClient.subscribe(subRequest); 

Answer 1

這個怎麼樣？

1. 列出了所有訂閱
2. 循環，直到你找到端點（ 「12712438216」），然後得到阿爾恩

3. 執行退訂（）函數。

   ListSubscriptionsResult listResult = snsClient.listSubscriptions(); 
   List<Subscription> subscriptions = listResult.getSubscriptions(); 
   String arn=""; 
   for (Subscription subs : subscriptions) { 
       if(subs.getProtocol().equals("sms") && subs.getEndpoint().equals("12712438216")) { 
        arn = subs.getTopicArn(); 
        break; 
       } 
   } 
   if(!arn.equals("")) { 
       snsClient.unsubscribe(arn); 
   }
