empty content-type when calculating canonical_string in the client

[aalbagarcia]

Hi:

I think I'm doing something wrong. When calculating the canonical_string, I'm getting an empty content-type in the client but a text/plain content type in the server. The result is that the request cannot be autenticated:

Client canonical string: ,,/request-url,date Server canonical string: text-plain,,/request-url,date

I've tested it with a simple GET request. I'm using Rails4 and ruby 2.0.0-p247

My model is using Activeresource to craft the request:

class Guide < ActiveResource::Base self.site = ENV['API_BASE_URL'] with_api_auth ENV['APP_KEY'], ENV['APP_SECRET'] end

I could make it work with this (ugly and quick) patch to Headers.canonical_string:

    # Returns the canonical string computed from the request's headers
    def canonical_string
      content_type = @request.content_type.blank? ? 'text/plain' : @request.content_type
      [ content_type,
        @request.content_md5,
        @request.request_uri.gsub(/http:\/\/[^(,|\?|\/)]*/,''), # remove host
        @request.timestamp
      ].join(",")
    end

Is there a way to specify a default content type for the request?

Thanks.

Note: I'm quite new to ruby and rails.

This is strange. Isn't ActiveResource setting the content type for either a json or xml request?
