How can I answer a POST request with a static file in Sinatra?

Question

In Sinatra, if you have a "GET /images/photo1.jpg" request... you can save a lot of time by making a "public" directory. Any route not found is assumed to be inside your "public" directory.

However this seems to work just for GET requests. Is there a way to do something similar for POST requests?

Either:

• Turning on some static method?
• Maybe forging an inner request?
• Duplicating functionality?

Any ideas? Is this even a bug?

PS: I know it's not RESTful to ask for files in a POST request, unfortunately Facebook works that way.

Answer 1

That sounds like something you should attack with rack middleware.

Answer 2

The send_file helper is what you want.

send_file "/your/file.txt", {:filename=>"foobar.dat"}
