AWS S3允许Cognito用户访问存储桶前缀

Question

I have the following setup:

user logs in with cognito. He should now be able to use an s3 item url as the src of an html5 video.

<video src='http://aws.s3.somebucket/userId/videoId.mp4' />

I have managed to use the sdk for the login and now have the authorization token on the client. How do I setup the bucket to allow access to the directory matching the userId, and how can I trigger/pass the authorization token?

Answer 1

You should integrate your user pool with Federated identities following this .

Setup the identity pool for S3 access following this .

After this you will get AWS credentials which would allow the user to only access based on the identityId.
