                var request = new PutBucketNotificationRequest()
                {
                    BucketName = bucketName,
                };

                // Defines the topic to use when sending a notification.
                var topicConfig = new TopicConfiguration()
                {
                    Events = new List<EventType> { EventType.ObjectCreatedCopy },

                request.QueueConfigurations = new List<QueueConfiguration>
                {

启用存储桶的指定通知

以下 put-bucket-notification-configuration 示例将通知配置应用于名为 my-bucket 的存储桶。文件 notification.json 是当前文件夹中的一个 JSON 文件，用于指定 SNS 主题和要监控的事件类型。

aws s3api put-bucket-notification-configuration \
    --bucket my-bucket \
    --notification-configuration file://notification.json

notification.json 的内容：

{
    "TopicConfigurations": [
        {
            "TopicArn": "arn:aws:sns:us-west-2:123456789012:s3-notification-topic",
            "Events": [
                "s3:ObjectCreated:*"
            ]
        }
    ]
}

SNS 主题必须附加一个 IAM 策略，以允许 Amazon S3 向其发布。

{
    "Version": "2008-10-17",
    "Id": "example-ID",
    "Statement": [
        {
            "Sid": "example-statement-ID",
            "Effect": "Allow",
            "Principal": {
                "Service": "s3.amazonaws.com"
            },
            "Action": [
                "SNS:Publish"
            ],
            "Resource": "arn:aws:sns:us-west-2:123456789012::s3-notification-topic",
            "Condition": {
                "ArnLike": {
                    "aws:SourceArn": "arn:aws:s3:*:*:my-bucket"
                }
            }
        }
    ]
}
