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:
So what's the most robust+portable way to do it?
I would usually go for request.format and request.content_type for reading these header fields.
EDIT: found a bit more on this that might help: https://stackoverflow.com/a/1595453/624590
You don't need to parse the content_type string, Rails has already done this for you. Just check:
request.format.symbol == :json
Another way of writing it:
No need to call #symbol since equals is overloaded:
request.format == :json
request.format == 'application/json'
For me the best way to check if incoming request is a json was:
if request.content_type =~ /json/
