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

Question

我通过java SDK创建了AWS S3和SNS。现在我试图为创建的S3存储桶设置事件。下面是我的代码片段

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);
}

}

但是上面的代码会引发以下错误

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实现这一点

Answer 1

我在使用python SDK时也遇到了类似的问题。当您在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。我在你的代码中没有看到这样做。 很抱歉，我不熟悉java SDK，我不知道到底需要添加什么，但在SNS上添加权限应该是正确的方向
