Remove charset from Rails content type

I have a old-stupid service making request to my app that fails when the Content-Type include the charset line

Content-Type    text/html; charset=utf-8

and I don't know how to remove it from my rails response. Every time that I over开发者_StackOverflowride the headers forcing just the first part (Content-Type text/html) Rails adds the charset to the header...


For Rails 3/4, the code that handles this is in ActionDispatch::Response.assign_default_content_type_and_charset! in actionpack/lib/action_dispatch/http/response.rb.

Setting response.headers['Content-Type'] instead of response.content_type should eliminate the charset. Chubas' solution does this for all responses.


For Rails 2, the code that handles this is in content_type= and charset= in actionpack/lib/action_controller/response.rb.

As Carson's solution describes, setting ActionController::Base.default_charset = nil should eliminate the charset.


This worked for me:

class MyController

  after_filter :remove_charset

  def remove_charset
    headers['Content-type'] = "text/html"
  end
end

If you're working on development, make sure you clear your browser's cache.

There is this method, but didn't work for me. I don't know why, it may even be a bug.


The only way I was able to get it to work is by setting the default charset

ActionController::Base.default_charset = nil

Also, setting the Content-Transfer-Encoding header to binary will turn off the charset.


Putting this in the controller did it for me:

ActionDispatch::Response::default_charset = nil

I put in in my base controller to remove it from all responses.
