Setting http headers RSpec 2.4 / Rails 3

Question

I am getting started with RSpec. I have a new rails 3 app which uses the HTTP_ACCEPT_HEADER or the request 2 letter subdomain to set the application language and redirect accordingly. I am successfully testing my redirection code using Cucumber.

Now I want to write my controller specs and I need to set the request subdomain before my test.

In my cucumber steps, I can specify:

header 'HTTP_HOST', 'es.mysite.local'
visit '/'

But when I try to do this in a spec file

header 'HTTP_HOST', 'es.mysite.local'
get 'index'

I get this error:

Failure/Error: header 'HTTP_HOST', "es.mysite.local"
 LoadError:
   no such file to load -- action_controller/integration

Any clue on how to solve this?

Answer 1

Try this:

request.env['HTTP_HOST'] = 'es.mysite.local'
get 'index'

Answer 2

Setting an HTTP header for every request in rspec is also possible. Add to your spec_helper inside the RSpec.configure do |config| block:

config.before(:each) do |x|
    x.request.env['HTTP_ACCEPT_LANGUAGE'] = 'de-CH,de;q=0.8,en;q=0.6'
end

Answer 3

The previous answer is correct, and in general the name of the header should be in all caps, prefixed with HTTP_, and separated with underscores. For example the "If-Modified-Since" header can be set with:

request.env['HTTP_IF_MODIFIED_SINCE'] = Time.now.httpdate
