Request header field Content-Type is not allowed by Access-Control-Allow-Headers

[davide.porrovecchio]

I get this error message when trying to add a new post using the User API key feature.
As discussed previously for different values, I think Content-Type should be also added to Access-Control-Allow-Headers header as defined in https://github.com/discourse/discourse/blob/master/config/initializers/008-rack-cors.rb#L42

Here is a PR that fixes this little bug.

Seems good to me, thanks!
