Question

所以我正在编写一些返回并处理json的API控制器。一个特殊的是会话控制器。我这样设置路线：

注意：（我只向您展示销毁方法，因为这是我唯一遇到问题的方法......）

  namespace :api do
    namespace :v1 do
      resource :users
      resources :sessions
    end
  end

然后我有以下路线：

   api_v1_sessions GET    /api/v1/sessions(.:format)          api/v1/sessions#index
                    POST   /api/v1/sessions(.:format)          api/v1/sessions#create
 new_api_v1_session GET    /api/v1/sessions/new(.:format)      api/v1/sessions#new
edit_api_v1_session GET    /api/v1/sessions/:id/edit(.:format) api/v1/sessions#edit
     api_v1_session GET    /api/v1/sessions/:id(.:format)      api/v1/sessions#show
                    PATCH  /api/v1/sessions/:id(.:format)      api/v1/sessions#update
                    PUT    /api/v1/sessions/:id(.:format)      api/v1/sessions#update
                    DELETE /api/v1/sessions/:id(.:format)      api/v1/sessions#destroy

最后，我为api/v1/sessions#destroy：

销毁了这样的代码

    def destroy
      @user = User.find_by auth_token: param[:auth_token]
      return invalid_user_crendentials unless @user

      cookies.delete(@user.auth_token)
      render json: { user_id: @user.id }, status: 200
    end

然后我为这个特定的动作编写了以下规范测试：

 context "Destroy a session" do
    it "should NOT destroy a session" do
        post :destroy
        response.response_code.should == 401
    end

    it "should NOT destroy a session with invalid token" do
        post :destroy, auth_token: '34534534'
        response.response_code.should == 401
    end

    it "should destroy a session based on valid data" do
        post :destory, auth_token: @user.auth_token
        json = JSON.parse response.body
        json.to_json.should have_json_path('user_id')
        response.response_code.should == 200
    end
  end

但是当我跑步时，我得到了：

No route matches {:auth_token=>"34534534", :controller=>"api/v1/sessions", :action=>"destroy"}
 No route matches {:auth_token=>"QfEg4oa0UdhJF4K1VIBADg", :controller=>"api/v1/sessions", :action=>"destory"}
No route matches {:controller=>"api/v1/sessions", :action=>"destroy"}

没有路线匹配？一点都没有？

Answer 1

将post更改为delete

context "Destroy a session" do
  it "should NOT destroy a session" do
      delete :destroy
      response.response_code.should == 401
  end

  it "should NOT destroy a session with invalid token" do
      delete :destroy, auth_token: '34534534'
      response.response_code.should == 401
  end

  it "should destroy a session based on valid data" do
      delete :destory, auth_token: @user.auth_token
      json = JSON.parse response.body
      json.to_json.should have_json_path('user_id')
      response.response_code.should == 200
  end
end

您可以在rake routes输出中看到您的销毁操作仅接受delete次请求：

DELETE /api/v1/sessions/:id(.:format) api/v1/sessions#destroy

它还在寻找一个:id参数。我想您想要在控制器中将param[:auth_token]更改为param[:id]，并在规范中将auth_token更改为id。

Answer 2

您的路线都希望传递id参数。

DELETE /api/v1/sessions/:id

您的测试正在传递auth_token。更改测试以传递id。

注意：您的测试确实应该是delete :destroy而不是post，而您的第三次测试也会在:destroy中出现拼写错误。
