使用rspec测试oauth2 get_token



我正在为oauth2身份验证的get_token部分创建一个控制器规范。此时,用户已授权我的应用程序,我需要生成并保存令牌和其他信息。

Failure/Error: get :auth, { code: "auth_code", scope: "read_write" }
     OAuth2::Error:
       {:token_type=>"bearer", 
        :stripe_publishable_key=>"PUBLISHABLE_KEY", 
        :scope=>"read_write", 
        :livemode=>"false", 
        :stripe_user_id=>"USER_ID",  
        :refresh_token=>"REFRESH_TOKEN", 
        :access_token=>"ACCESS_TOKEN"}

这是控制器代码。Rspec说它在get_token上失败。

require 'oauth2'
def auth
  code = params[:code]
  client = oauth_client
  token_response = client.auth_code.get_token(code, params: { scope: 'read_write' })
  token = token_response.token

测试是这样的。webmock应该拦截get_token。这是rspec建议的自动生成的webmock,我在主体中填充了适当的请求和响应主体。

before do
  stub_request(:post, "https://connect.stripe.com/oauth/token").
    with(:body => {"client_id"=>"CLIENT_ID",
                   "client_secret"=>"SOME_SECRET",
                   "code"=>"auth_code",
                   "grant_type"=>"authorization_code",
                   "params"=>{"scope"=>"read_write"}},
         :headers => {'Accept'=>'*/*',
                      'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3',
                      'Content-Type'=>'application/x-www-form-urlencoded',
                      'User-Agent'=>'Faraday v0.9.0'}).
    to_return(:status => 200,
              :body => {token_type: "bearer",
                        stripe_publishable_key: "PUBLISHABLE_KEY",
                        scope: "read_write",
                        livemode: "false",
                        stripe_user_id: "USER_ID",
                        refresh_token: "REFRESH_TOKEN",
                        access_token: "ACCESS_TOKEN"},
              :headers => {})
end
describe "#auth" do
  it "creates a payment gateway" do
    get :auth, { code: "auth_code", scope: "read_write" 
  end
end

这个过程已经在实践中工作了,所以至少控制器代码不应该受到指责。我做错了什么?

经过努力,遇到同样的问题,我有了解决方案。如果在存根请求中返回报头,则将其设置为空白。oauth2 gem使用Content-Type来定义如何解析正文。试着用这样的方式来保存存根:

stub_request(:post, "https://connect.stripe.com/oauth/token").
    with(:body => {"client_id"=>"CLIENT_ID",
                   "client_secret"=>"SOME_SECRET",
                   "code"=>"auth_code",
                   "grant_type"=>"authorization_code",
                   "params"=>{"scope"=>"read_write"}},
         :headers => {'Accept'=>'*/*',
                      'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3',
                      'Content-Type'=>'application/x-www-form-urlencoded',
                      'User-Agent'=>'Faraday v0.9.0'}).
    to_return(:status => 200,
              :body => {token_type: "bearer",
                        stripe_publishable_key: "PUBLISHABLE_KEY",
                        scope: "read_write",
                        livemode: "false",
                        stripe_user_id: "USER_ID",
                        refresh_token: "REFRESH_TOKEN",
                        access_token: "ACCESS_TOKEN"},
              :headers => { 'Content-Type'=> 'application/json;charset=UTF-8'})

我认为你得到这个错误,因为你只stub了oauth会话的一部分,即你试图发送一个由webmock提供的陈旧令牌(或类似的东西)。

我建议使用特殊的工具:Stripe -ruby-mock gem,它是专门为测试Stripe API而设计的。

作为替代方案,您可以使用VCR gem(这里是文档),它允许将所有http会话写入磁盘并将其作为现场播放。很好的工具,强烈推荐。
