链接到不带URL的S3文件-Rails-AWS-SDK

Question

I have an S3 account, on which are stored videos which I need to play using an HTML5 Video element inside a rails application.

Is it possible for me to be able to load the videos into the player without making the video public and directly linking to it?

I have the gem aws-sdk and I read through the documentation and didn't find any information about this.

Excuse me? How is it unclear what I'm asking? It's not really possible to make it clearer so I guess I'll basically restate what I already said.

I need to be able to this:

<video src="<url of file on S3>"> without making the file public in S3 so anybody can download it.

Answer 1

Look ar presigned URLs. Use the Presigner in the ruby sdk on the server to generate a presigned URL (for get method) for the key and insert that into the html.

Answer 2

There is an article page about doing this using the aws-sdk.

http://docs.aws.amazon.com/AmazonS3/latest/dev/UploadObjectPreSignedURLRubySDK.html

I've only ever used Paperclip to do so.

To access private content in S3 from your rails application, there are multiple approaches available

• Create a Sign URL using Ruby AWS SDK from your Rails Backend and return the URL to the browser so that your HTML5 player can access them
• Using AWS STS and AWS Ruby SDK at Rails Backend, generate a temporarily access token (Which has grants to s3 bucket) and return it to the browser, where browser can use AWS JS SDK + Token to request the file

For better performance use AWS Cloufront RTMP distributions for the Videos which serves the files from S3 with Signed URLs and Origin Access Identity limiting public access
