ruby - 我如何在 rspec for sinatra 中使用 omniauth？

Question

简化版:

使用 sinatra 的 omniauth gem，我无法让 rspec 登录工作并为后续请求保留我的 session 。

基于 http://benprew.posterous.com/testing-sessions-with-sinatra 的建议，并关闭 session ，我已将问题隔离到此:

  app.send(:set, :sessions, false)    # From http://benprew.posterous.com/testing-sessions-with-sinatra
  get '/auth/google_oauth2/callback', nil, {"omniauth.auth" => OmniAuth.config.mock_auth[:google_oauth2] }
  # last_request.session => {"uid"=>"222222222222222222222", :flash=>{:success=>"Welcome"}}
  # last_response.body => ""

  follow_redirect!
  # last_request.session => {:flash=>{}}
  # last_response.body => Html for the homepage, which is what I want

如何让 rspec 遵循重定向并保留 session 变量？这在 Sinatra 中可能吗？

来自 http://benprew.posterous.com/testing-sessions-with-sinatra ，似乎我必须在每个需要登录的 get/post 请求上发送 session 变量，但这在重定向的情况下不起作用。

详情:

我正在尝试通过以下设置在 sinatra 中使用 omniauth gem:

spec_helper.rb

ENV['RACK_ENV'] = 'test'

# Include web.rb file
require_relative '../web'
# Include factories.rb file
require_relative '../test/factories.rb'

require 'rspec'
require 'rack/test'
require 'factory_girl'
require 'ruby-debug'

# Include Rack::Test in all rspec tests
RSpec.configure do |conf|
  conf.include Rack::Test::Methods
  conf.mock_with :rspec
end

web_spec.rb

describe "Authentication:" do
  before do
    OmniAuth.config.test_mode = true
    OmniAuth.config.add_mock(:google_oauth2, {
      :uid => '222222222222222222222',
      :info => {
        :email => "someone@example.com",
        :name => 'Someone'
      }
    })
  end

  describe "Logging in as a new user" do
    it "should work" do
      get '/auth/google_oauth2/'

      last_response.body.should include("Welcome")
    end
  end
end

尝试进行身份验证时，我得到一个 <h1>Not Found</h1>回复。我错过了什么？

关于 Integration testing omn​​iauth 文档的页面，它提到添加两个环境变量:

before do 
  request.env["devise.mapping"] = Devise.mappings[:user] 
  request.env["omniauth.auth"] = OmniAuth.config.mock_auth[:twitter] 
end

但正如我所补充的那样，似乎仅适用于 rails

request.env["omniauth.auth"] = OmniAuth.config.mock_auth[:google_oauth2] 

到我的before阻止我的规范，我得到这个错误:

Failure/Error: request.env["omniauth.auth"] = OmniAuth.config.mock_auth[:google_oauth2]
 ArgumentError:
   wrong number of arguments (0 for 1)

编辑:

调用 get与

get '/auth/google_oauth2/', nil, {"omniauth.auth" => OmniAuth.config.mock_auth[:google_oauth2]}

似乎给我last_request.env["omniauth.auth"]等于

 {"provider"=>"google_oauth2", "uid"=>"222222222222222222222", "info"=>{"email"=>"someone@example.com", "name"=>"Someone"}}

这似乎是对的，但是 last_response.body仍然返回

<h1>Not Found</h1>

Answer 1

部分答案...

回调 url 工作得更好，添加了请求环境变量:

get '/auth/google_oauth2/callback', nil, {"omniauth.auth" => OmniAuth.config.mock_auth[:google_oauth2]}
follow_redirect!

last_response.body.should include("Welcome")

但是，这不适用于重定向后的 session ，这是我的应用知道有人登录所必需的。更新了问题以反射(reflect)这一点。
