I use Scala and Lift for REST web-services and I have a method that generates dynamic jpg images that should be made accessible via a Get Request, so that for each Get-Request the method generates an image again and sends it back in the response.
I made a case in serve:
case "img.jpg" :: Nil Get _ => Full(OkResponse())
case _ => Full(NotFoundResponse())
But this case does not seem to be recognised, it always catches the Default-Case.
What is the proper way to serve routes on a . url? And what response type can be used to deliver the jpg?
The file extension is handled separately from the rest of the path, so matching as you do above won't work. You can see some more discussion about this in the Lift Cookbook.
To make the above work, you should be able to do this:
case "img" :: Nil Get req if req.path.suffix == "jpg" => Full(OkResponse())
I believe you can also use the Req object, which will let you specify the suffix like this:
case Req("img" :: Nil, "jpg", GetRequest) => Full(OkResponse())
