Get Content Type of Request

To find the incoming content type, docs say:

 request.headers["Content-Type"] # => "text/plain"

But I found by trial-and-error, that doesn't work, but this does:

 request.headers["CONTENT_TYPE"]=='application/json'

So what's the most robust+portable way to do it?

Solution

  • I would usually go for request.format and request.content_type for reading these header fields.
