我无法将SNS消息作为电子邮件发布

Question

我使用以下代码：

 AmazonSNSClient snsClient = new AmazonSNSClient(credentials);
 snsClient.setRegion(Region.getRegion(Regions.SA_EAST_1));
                    String msg = "My text published to SNS topic with email endpoint";
                    String arn = "XXXXX";
                    PublishRequest publishRequest = new PublishRequest("topicARN here",msg);
                    PublishResult publishResult = snsClient.publish(publishRequest);

但我得到了ERROR。

  

“InvalidParameterException：Status Code：400，AWS Service：AmazonSNS，   AWS请求ID：446fef49-4eba-5484-ba4c-bf82682cdc46，AWS错误代码：   InvalidParameter，AWS错误消息：参数无效：TopicArn“

任何人都可以帮我吗？

我认为您的主题ARN尚不存在。检查它是否存在或明确创建它。

这里有HelloWorldSNS给你：

public class HelloWorldSNS {

    public static void main(String[] args) throws Exception {

        AmazonSNSClient client = Region.getRegion(Regions.EU_CENTRAL_1).createClient(AmazonSNSClient.class, null,
                null);
        CreateTopicResult createTopic = client.createTopic("myTopic");
        SubscribeResult subscribe = client.subscribe(createTopic.getTopicArn(), "email", "some@email.com");
        PublishRequest publishRequest = new PublishRequest(createTopic.getTopicArn(), "Test message");
        client.publish(publishRequest);
    }
}
