How to set request headers in rspec request spec?

You should be able to specify HTTP headers as the third argument to your get() method as described here:

and here

So, you can try something like this:

get '/my/path', nil, {'HTTP_ACCEPT' => "application/json"}

ruby-on-rails json testing rspec

I used this in Test::Unit:

@request.env['HTTP_ACCEPT'] = "*/*, application/youtube-client"get :index

ruby-on-rails json testing rspec

I'm adding this here, as I got majorly stuck trying to do this in Rails 5.1.rc1

The get method signature is slightly different now.

You need to specify the options after the path as keyword arguments, i.e.

get /some/path, headers: {'ACCEPT' => 'application/json'}

FYI, the full set of keywords arguments are:

params: {}, headers: {}, env: {}, xhr: false, as: :symbol
