ruby-on-rails - 网络模拟 : Rspec - Test Facebook Validation by using JSON response

Question

我很难为我的程序编写规范，因为我需要在填写所有正确的格式信息后验证 facebook ID。我的 facebook ID 是从 JSON 响应中检索的，所以我不确定如何在我的规范中描述这一点。我对这个领域很陌生，我已经被困在这一点上很长时间了。如果有一些示例代码可以帮助我，我将不胜感激。以下是我的半成品规范。

场景:使用给定 Fbid 的用户通过使用“http://graph.facebook.com”(JSON 响应)匹配用户名和 fbid 来验证 Facebook 页面。

我的 github 网址:https://github.com/amycheong/company_list

更新:我使用过 WebMock 但最终得到:

 1) Companies new company create with valid information correct facebook id should validate fbid
 Failure/Error: Company.validate_fbid('pepsi')['username'].should == "pepsi"
 WebMock::NetConnectNotAllowedError:
   Real HTTP connections are disabled. Unregistered request: GET http://graph.facebook.com:443/pepsi with headers {'Accept'=>'*/*', 'User-Agent'=>'Ruby'}

   You can stub this request with the following snippet:

   stub_request(:get, "http://graph.facebook.com:443/pepsi").
     with(:headers => {'Accept'=>'*/*', 'User-Agent'=>'Ruby'}).
     to_return(:status => 200, :body => "", :headers => {})

   registered request stubs:

   stub_request(:get, "https://graph.facebook.com/pepsi")

   ============================================================

我使用过 WebMock.disable_net_connect!(:allow => " https://graph.facebook.com/ ") 但问题仍然存在。

模型文件:

def self.validate_fbid(fbid, format = :json)
    uri = URI.parse("https://graph.facebook.com/#{fbid}")
    data = Net::HTTP.get(uri)
    return JSON.parse(data['username'])          
end

规范文件:

before(:each) do
        stub_request(:get, "https://graph.facebook.com/pepsi").to_return(:body => { 'username' => 'pepsi'})
    end 

    describe "correct facebook id" do               
        #validate fbid
        it "should validate fbid" do            

            Company.validate_fbid('pepsi')['username'].should == "pepsi"
            WebMock.should have_requested(:get, "https://graph.facebook.com/pepsi")
        end

    end

Controller :

def create 
@company = Company.new(params[:company])

uri = URI("http://graph.facebook.com/" + @company.fbid)
data = Net::HTTP.get(uri)
username = JSON.parse(data)['username']
if !username.nil? 
    if @company.name.downcase == username.downcase
        if @company.save 
            @message = "New company created"
            redirect_to root_path
        else 
            @message = "Company create attempt failed. Please try again."
            render 'new' 
        end 
    else 
        @message = "Invalid facebook id"
        render 'new' 
    end
else 
    @message = "No such facebook id"
    render 'new'            
end

Answer 1

您正在 stub HTTPS 请求，但使用端口 443 执行 HTTP，这就是 Webmock 找不到正确 stub 的原因。
