Ruby on rails 使用自定义会话控制器在正确登录时设计401返回

我在设计和创建自定义会话控制器方面遇到了一些问题

我正在创建一个应用程序，我希望json作为登录的唯一形式。这就是我到目前为止所做的

会话控制器

class SessionsController < Devise::SessionsController

  # Create operation should login the user and respond with json status
  def create
    resource = warden.authenticate!(:scope => resource_name, :recall => "sessions#failure")
    sign_in(resource_name, resource)

    respond_to do | format |
      format.json { render :json => { :success => true, :user => resource }, :status => 200 }
    end
  end

  def failure
    return render :status => 401, :json => {:success => false, :errors => ["Login failed."]}
  end  

end

我正在尝试运行的测试：

  devise_for :users, :controllers => {:sessions => "sessions"}, :skip => [:sessions] do
    get '/login' => 'sessions#new', :as => :new_user_session
    post '/login' => 'sessions#create', :as => :user_session
    get '/logout' => 'sessions#destroy', :as => :destroy_user_session
  end

require 'spec_helper'

describe SessionsController do
  include Devise::TestHelpers

  describe "POST 'create'" do
      describe "invalid signin" do

        before(:each) do
          @attr = { :email => "master_yoda@jedi.com", :password => "invalid" }
          request.env["devise.mapping"] = Devise.mappings[:user]
        end

        it "should return an error" do
          post :create, :user => @attr,  :format => :json

          puts @response.body
        end

      end
  end
end

现在，当我运行这个测试时。我得到的是http响应而不是json：

#<ActionDispatch::Response:0x00000004cb8bb8>

第一次执行发送401，然后后续执行发送200

失败：

  devise_for :users, :controllers => {:sessions => "sessions"}, :skip => [:sessions] do
    get '/login' => 'sessions#new', :as => :new_user_session
    post '/login' => 'sessions#create', :as => :user_session
    get '/logout' => 'sessions#destroy', :as => :destroy_user_session
  end

require 'spec_helper'

describe SessionsController do
  include Devise::TestHelpers

  describe "POST 'create'" do
      describe "invalid signin" do

        before(:each) do
          @attr = { :email => "master_yoda@jedi.com", :password => "invalid" }
          request.env["devise.mapping"] = Devise.mappings[:user]
        end

        it "should return an error" do
          post :create, :user => @attr,  :format => :json

          puts @response.body
        end

      end
  end
end

我不明白我做错了什么或者这里发生了什么。我浏览了很多东西的帖子，没有找到具体的答案

希望有人能帮忙：）

谢谢

我也有同样的问题。我不明白为什么response.body返回“ActionDispatch:：response…”而不是实际的响应正文。这似乎是监狱长的问题。请验证！仅限在线测试。正如您所描述的那样，使用curl也适用于我。最后，我只是将规范更改为以下内容：

context "with invalid credentials" do
  it "re-renders login page" do
    post :create, person: { email: @person.email, password: 'badpassword' }
    response.should be_ok
    response.should render_template("devise/sessions/new")
  end

  it "returns an error with json" do
    post :create, person: { email: @person.email, password: 'badpassword' }, format: 'json'
    response.status.should == 403
  end
end

---

虽然您无法完全测试json响应，但至少您仍在测试响应错误状态代码。

这是Desive测试助手中的一个错误。它在。

的同一条船上被修复，也没有找到答案：（测试失败，因为response.body是HTTP响应而不是JSON。
