录像机正在返回未处理的HTTP请求错误

问题描述：

我有一个网站可以保存用户提交的链接。创建操作需要一个url，并从html中的og：标签中提取数据。该应用程序本身工作正常，但我无法在RSpec与VCR测试它。录像机正在返回未处理的HTTP请求错误

测试通过没有VCR罚款，但需要很长时间（实际的代码有多个HTTP请求）。当我尝试用VCR运行测试时，出现以下错误。我该如何解决这个问题？

Failure/Error: click_button 'submit' 
VCR::Error::UnhandledHTTPRequestError: 
    ================================================================================ 
    An HTTP request has been made that VCR does not know how to handle: 
    GET http://espn.go.com/golf/masters13/story/_/id/9171606

links_controller.rb

def create 
    @link = Link.new(params[:link]) 
    if @link.save 
    @link.title_from_url(@link.url) 
    else 
    render action: "new" 
    end 
end

Link.rb

def title_from_url(url) 
    if !Nokogiri::HTML(open(url)).css("meta[property='og:title']").blank? 
    self.title = Nokogiri::HTML(open(url)).css("meta[property='og:title']").first.attributes["content"].text 
    self.save  
    end 
end

link_pages_spec.rb

require 'spec_helper' 

describe 'Link' do 
    subject { page } 
    before do 
    visit root_path 
    click_link "create link" 
    end 
    describe "should be created with valid form" do 
    VCR.use_cassette "link/create" do 
     before do 
     fill_in "enter url", with: "http://espn.go.com/golf/masters13/story/_/id/9171606" 
     click_button "submit" 
     end 
     it { should have_selector('h2', text:'Adam Scott 1st Aussie to win Masters')}   
    end 
    end 
end

规格/支持/ vcr_setup.rb

VCR.configure do |c| 
    c.cassette_library_dir = 'spec/vcr_cassettes' 
    c.hook_into :fakeweb 
end

答

我有两件事情是错误的。首先，需要通过capybara-mechanize创建我的Capybara.current_driver = :mechanize宝石。其次，需要将VCR块放入一个块中（而不是描述）。所以下面的代码工作。

require 'spec_helper' 

describe 'Link' do 
    subject { page } 
    it "should be created with valid form" do 
    VCR.use_cassette "link/create" do 
     Capybara.current_driver = :mechanize 
     visit root_path 
     click_link "create link" 
     fill_in "enter url", with: "http://espn.go.com/golf/masters13/story/_/id/9171606" 
     click_button "submit" 
     page.should have_selector('h2', text:'Adam Scott 1st Aussie to win Masters')   
    end 
    end 
end
