问题 I am currently hosting a static website on S3 which is using redirection rules to re-route the request to a lambda function. The problem is I have two buckets that are both acting as static websites (sandbox vs production) and I need to be able to point them to the same lambda function but be able to tell them apart when the function is run. Whether it's a header, a GET parameter, string manipulation, anything I can use to determine which bucket the request came from. Does anyknow know how

问题 I use multiple AWS API Gateway for many of our backend services. This is the standard structure of the Gateway (in relation to my question); API Gateway 2 stages (test and prod) AWS CLI Tool for automated changes and deployments The problem I'm having (this has been since I started using AWS API Gateway); The Gateway manages versionsing of the API perfectly fine, however, not model versioning...

问题 I'm using AWS Lambda to create an elastic transcoder job with HLS content protection. Following the doc here: http://docs.aws.amazon.com/elastictranscoder/latest/developerguide/content-protection.html At the end it says: "Note If you choose No Store, Elastic Transcoder returns your data key as part of the job object, but does not store it.
