ruby-on-rails - 使用 devise_token_auth +omniauth 请求规范

Question

我目前正在使用 Rails 5 编写一个 API，使用 devise_token_auth 和 omniauth 作为身份验证策略。

为了检查omniauth身份验证是否有效，我编写了一个请求规范:

OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[:facebook] = OmniAuth::AuthHash.new(
  {
      provider: 'facebook',
      uid: '123456'
  })
Rails.application.env_config["devise.mapping"] = Devise.mappings[:user]
Rails.application.env_config["omniauth.auth"]  = OmniAuth.config.mock_auth[:facebook]
get '/omniauth/facebook/callback'
expect(response).to have_http_status(:ok)

当我运行测试时，我必须遵循以下错误:

NoMethodError: undefined method `[]' for nil:NilClass
/Users/gaetan/.rvm/gems/ruby-2.3.1/gems/devise_token_auth-0.1.39/app/controllers/devise_token_auth/omniauth_callbacks_controller.rb:14:in `redirect_callbacks'

这是第 14 行:

devise_mapping = [request.env['omniauth.params']['namespace_name'],

所以我猜这是因为 omniauth.params 是 nil。这是否意味着我还必须模拟参数？怎么办？

Answer 1

Controller

(例如:Users::OmniauthCallbacksController)

def omniauth_params
  request.env['omniauth.params']
end

规范

allow_any_instance_of(Users::OmniauthCallbacksController).to(receive(:omniauth_params).and_return('namespace_name' => 'namespace_name'))

或

allow_any_instance_of(Users::OmniauthCallbacksController).to(receive(:omniauth_params).and_return(OmniAuth::AuthHash.new({:namespace_name => 'namespace_name'})))
