AWS SNS服务短信取消订阅

Question

我正在使用AWS SNS服务将警报消息发送到用户手机。但是，用户取消订阅该主题仍然可以从该主题获取消息。停止让消息用户发送消息STOP .Following code snippet for creating and订阅主题。

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

这个怎么样？

1. 列出所有订阅
2. 循环直到找到endPoint（＆＃34; 12712438216＆＃34;），然后获取arn

3. 执行unsubscribe（）函数。

   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);
   }
