S3预签名网址-检查是否使用了网址？ [英] S3 pre-signed url - check if url was used?

问题描述

我正在使用S3预签名网址直接从客户端上传图片。
仅当我确定使用了URL并上传了新图像时，我才希望将消息推送到SQS队列。

I'm using S3 pre-signed url for uploading images directly from client-side. I would like to be able to push a message to SQS queue only when I'm sure that the url was used and a new image was uploaded.

给定一个预签名的URL，我如何验证它是否被使用？

Given a pre-signed url, how can I validate if it was used?

推荐答案

您真的需要知道何时使用预签名吗？签名的URL已被使用？还是只要有新对象上传到S3存储桶就可以向SQS发送新消息？由于您将上传限制为使用预先签名的URL不能达到您的目标？

Do you really need to know when a pre-signed URL has been used? Or can you just send a new message to SQS whenever a new object is uploaded to your S3 bucket? Since you are restricting uploads to using pre-signed URLs wouldn't that accomplish your goal?

S3内置支持向SQS，SNS或Lambda发送通知每当创建新对象时。您可以在这里阅读更多有关此内容的信息： http://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html#notification-how-to-event-types-and-destinations

S3 has built-in support for sending a notification to SQS, SNS or Lambda whenever a new object is created. You can read more about that here: http://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html#notification-how-to-event-types-and-destinations
