Rails 5 set Authorization header - ruby-on-rails

Question

I got JSON Web Token login going but am in the process of fixing my Rails 5 Controller tests.
I am trying to pass my JWT auth token to my GET request header.
So far, in my User Controller test, I have this test:
test "users should return list of users" do
User.create(#bob)
auth_token = log_in_as(#bob)
request.headers['Authorization'] = "JWT #{auth_token}"
get users_path
assert_response :success
assert_not response.body.empty?
end
So far that doesn't work, I get response not authenticated.
If I change it to like so:
test "users should return list of users" do
User.create(#bob)
auth_token = log_in_as(#bob)
get users_path, nil, { HTTP_AUTHORIZATION: "JWT #{auth_token}" }
puts "response = #{response.body}"
assert_response :success
assert_not response.body.empty?
end
I get this expected response:
response = {"users":[{"id":298486374,"name":"MyString","email":"MyString","cats":[]},{"id":980190962,"name":"MyString","email":"MyString","cats":[]},{"id":980190963,"name":"Bob","email":"bob#gmail.com","cats":[]}]}
but I also get a DEPRECATED WARNING:
DEPRECATION WARNING: ActionDispatch::IntegrationTest HTTP request
methods will accept only the following keyword arguments in future
Rails versions: params, headers, env, xhr
Examples:
get '/profile', params: { id: 1 }, headers: { 'X-Extra-Header' =>
'123' }, env: { 'action_dispatch.custom' => 'custom' }, xhr: true
So what is the recommended way to set HTTP Authorization header in Rails 5 ?

Answer 1

You need to include the params and headers key in the arguments see here.
get users_path, params: {}, headers: { HTTP_AUTHORIZATION: "JWT #{auth_token}" }
You first example probably isn't working because you are setting the JWT on Authorization and not HTTP_AUTHORIZATION.
request.headers['HTTP_AUTHORIZATION'] = "JWT #{auth_token}"
