POSTing raw JSON data with Rails 3.2.11 and RSpec

As far as I have been able to tell, sending raw POST data is no longer possible within a controller spec. However, it can be done pretty easily in a request spec:

describe "Example", :type => :request do
  params = { token: 0 }
  post "/user/reset_password", params.to_json, { 'CONTENT_TYPE' => 'application/json', 'ACCEPT' => 'application/json' }
  #=> params contains { "controller" => "user", "action" => "reset_password", "token" => 0 }
end
