AWS S3 notificationConfiguration引发无法验证以下目标配置（服务：Amazon S3）

Question

我已经通过java SDK创建了AWS S3和SNS。 现在，我正在尝试为创建的S3存储桶设置事件。 以下是我的代码段

private void createS3Event(String snsTopicARN) {
    AmazonS3Client s3Client = new AmazonS3Client();
    BucketNotificationConfiguration notificationConfiguration = new BucketNotificationConfiguration();
    TopicConfiguration topicConfiguration = new TopicConfiguration(snsTopicARN, EnumSet.of(S3Event.ObjectCreated));
    notificationConfiguration.addConfiguration("snsTopicConfig", topicConfiguration);

    String bucketName = "test-bucket";

    s3Client.setBucketNotificationConfiguration(bucketName, notificationConfiguration);
}

}

但是上面的代码抛出以下错误

Exception in thread "main" com.amazonaws.services.s3.model.AmazonS3Exception: Unable to validate the following destination configurations (Service: Amazon S3; Status Code: 400; Error Code: InvalidArgument; Request ID: 40F2EB4DB807BD38), S3 Extended Request ID: Cr3P1AZ4FuqHr2UrYBUc5U28uDNh4pWAtqGIRYgDlQsQ5VT4eJ4XK5z0BKdannipxRnEtLyi8jM=

如何使用Java API使其正常工作？

Answer 1

我在使用python SDK时遇到类似的问题。 在s3上设置事件以触发SNS时，您需要在SNS上添加权限以允许s3触发它。 我没有在您的代码中看到这样做。 对不起，我对Java SDK不熟悉，我不知道到底需要添加什么，但是在SNS上添加权限应该是正确的方向。
