预期响应为 <2XX:success>，但控制器测试为 <403: Forbidden>

Question

我正在尝试在 Ruby on Rails 6.0 应用程序上运行一个简单的测试，但出现 403 错误。

Alberts-MacBook-Pro:rr albertski$ rails test test/controllers/categories_controller_test.rb
Running via Spring preloader in process 72301
Run options: --seed 53214

# Running:

F

Failure:
CategoriesControllerTest#test_should_get_categories_index [/Users/albertski/Sites/rr/test/controllers/categories_controller_test.rb:10]:
Expected response to be a <2XX: success>, but was a <403: Forbidden>

categories_controller.rb

class CategoriesController < ApplicationController
  def index

  end

  def new

  end

  def show

  end
end

categories_controller_test.rb

require 'test_helper'

class CategoriesControllerTest < ActionDispatch::IntegrationTest
  def setup
    @category = Category.create(name: "sports")
  end

  test "should get categories index" do
    get categories_path
    assert_response :success
  end

end

application_controller.rb

class ApplicationController < ActionController::Base

  helper_method :current_user, :logged_in?

  def current_user
    @current_user ||= User.find(session[:user_id]) if session[:user_id]
  end

  def logged_in?
    !!current_user
  end

  def require_user
    if !logged_in?
      flash[:danger] = "You must be logged in to perform this action"
      redirect_to root_path
    end
  end
end

config/environments/test.rb

# The test environment is used exclusively to run your application's
# test suite. You never need to work with it otherwise. Remember that
# your test database is "scratch space" for the test suite and is wiped
# and recreated between test runs. Don't rely on the data there!

Rails.application.routes.default_url_options[:host] = 'http://localhost:3000'

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.
  config.hosts << "localhost:3000"

  config.cache_classes = false

  # Do not eager load code on boot. This avoids loading your whole application
  # just for the purpose of running a single test. If you are using a tool that
  # preloads Rails for running tests, you may have to set it to true.
  config.eager_load = false

  # Configure public file server for tests with Cache-Control for performance.
  config.public_file_server.enabled = true
  config.public_file_server.headers = {
    'Cache-Control' => "public, max-age=#{1.hour.to_i}"
  }

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false
  config.cache_store = :null_store

  # Raise exceptions instead of rendering exception templates.
  config.action_dispatch.show_exceptions = false

  # Disable request forgery protection in test environment.
  config.action_controller.allow_forgery_protection = false

  # Store uploaded files on the local file system in a temporary directory.
  config.active_storage.service = :test

  config.action_mailer.perform_caching = false

  # Tell Action Mailer not to deliver emails to the real world.
  # The :test delivery method accumulates sent emails in the
  # ActionMailer::Base.deliveries array.
  config.action_mailer.delivery_method = :test

  # Print deprecation notices to the stderr.
  config.active_support.deprecation = :stderr

  # Raises error for missing translations.
  # config.action_view.raise_on_missing_translations = true
end

我调试了get categories_path，它返回/categories。此外，在浏览器中查看/categories 路径时，我没有任何问题；它只发生在测试中。

Answer 1

我可以通过在我的测试中添加byebug 并打印出response 来找到问题，这指向了以下消息：

Blocked host: www.example.com

To allow requests to www.example.com, add the following to your environment configuration:

config.hosts << \"www.example.com\"

更新到config.hosts << "www.example.com" 解决了这个问题。

另外，不知道为什么我一开始就有config.hosts << "localhost:3000"。删除该行也可以解决问题。

Answer 2

删除/注释掉您可能拥有的config/application.rb 中的任何config.hosts << "your-hostname>"。

就我而言，我的 ngrok 在那里。

config.hosts << "2f0c5431228v.ngrok.io"
