我正在尝试为我正在构建的Rails应用编写请求规范，但是文档很少（或者我还没有找到合适的文档）。
我有一个companies资源，其中包含大多数常用的API端点：

# Routes -------------------------------------------------------------------
#    companies GET    /companies(.:format)          companies#index
#              POST   /companies(.:format)          companies#create
#  new_company GET    /companies/new(.:format)      companies#new
# edit_company GET    /companies/:id/edit(.:format) companies#edit
#      company GET    /companies/:id(.:format)      companies#show
#              DELETE /companies/:id(.:format)      companies#destroy
#              PATCH  /companies/:id(.:format)      companies#update

我希望我的规范指出，如果您在未登录时遇到这些端点，它们会将您重定向到登录页面。对于前三个端点（没有:id参数的端点），这很简单：

RSpec.describe 'Companies Endpoints', type: :request do    
  context 'with anonymous user' do
    it 'always redirects to sign-in page' do
      get '/companies'
      expect(response).to redirect_to(new_user_session_path)

      post '/companies'
      expect(response).to redirect_to(new_user_session_path)

      get '/companies/new'
      expect(response).to redirect_to(new_user_session_path)
  end
end

当端点包含一个URL参数（get '/companies/:id/edit'）时，请求的语法是什么？这是我到目前为止提出的语法：

RSpec.describe 'Companies Endpoints', type: :request do
  let :company { FactoryGirl.create(:company) }  # NOTE: this is new

  context 'with anonymous user' do
    it 'always redirects to sign-in page' do
      ...

      get "/companies/#{company.id}/edit"        # `company` is from the factory above
      expect(response).to redirect_to(new_user_session_path)

      ...
    end
  end

但我在想这是不是“正确”的路。
具体来说，www.example.com上的请求规范场景relishapp.com显示了作为POST请求的一部分使用params选项哈希，我想知道此选项哈希是否也适用于URL参数？

RSpec.describe "Widget management", :type => :request do
  it "creates a Widget and redirects to the Widget's page" do
    post "/widgets", :params => { :widget => {:name => "My Widget"} }
    ...
