Is it possible to use wildcards or catch-all paths in AWS API Gateway

Question

I am trying to redirect all traffic for one domain to another. Rather than running a server specifically for this job I was trying to use AWS API Gateway with lambda to perform the redirect.

I have this working ok for the root path "/" but any requests for sub-paths e.g. /a are not handled. Is there a way to define a "catch all" resource or wildcard path handler?

Answer 1

As of last week, API Gateway now supports what they call “Catch-all Path Variables”.

Answer 2

You can create a resource with path like /{thepath+}. Plus sign is important.

Then in your lambda function you can access the value with both

• event.path - always contains the full path
• or event.pathParameters.thepath - contains the part defined by you. Other possible use case: define resource like /images/{imagepath+} to only match pathes with certain prefix. The variable will contain only the subpath.

You can debug all the values passed to your function with: JSON.stringify(event)
