如何使用VCR和Webmock使用基本身份验证来存根发布请求？

免责声明：我是API的新手，经过一周的努力解决这个看似简单的问题，我已经远远超过了。

我有与Github的API交互的代码已经正确实现但我想回去使用RSpec，Webmock和VCR进行测试。

基本上，我有一个#create方法，允许用户在Github上创建一个新的存储库。

以下是该方法的代码：

def self.create（attributes）

post = HTTParty.post(
    'https://api.github.com/user/repos',

    :headers => {
        'User-Agent' => 'Githubrepo',
        'Content-Type' => 'application/json',
        'Accept' => 'application/json'
    },

    :basic_auth => {
        :username => attributes[:username],
        :password => attributes[:password]
    },

    :body => {
        'name' => attributes[:repository],
        'description' => attributes[:description]
    }.to_json
)
Githubrepo.parse_response_from(post, attributes[:wants_ssh])
end

所有这一切都是在给出具有某些属性的实际POST请求并将发布的信息存储到名为post的变量中，然后将其作为属性传递给另一个方法#parse_response_from 。这个#parse_response_from方法是我想要测试的方法，但我无法理解我的生活如何用Webmock和VCR模仿post属性。

这就是我需要模仿生产中的post变量：

基本上，我真正需要的是这个散列中的一些变量要传递给#parse_response_from方法。我现在测试它的方法是将某些静态键/值对存储到before块并测试该代码。这是一个看：

before(:each) do
    @api_data = { "name" => "test_repo",
                  "ssh_url" => "git@github.com:test_user/test_repo.git",
                  "clone_url" => "https://github.com/test_user/test_repo.git" 
                }
end

如何使用Webmock的stub_request将其存根并将其传递到VCR卡带？我已经看到很多用于存储GET的示例，但我不明白如何将{Web引用}用于POST。具体来说，我需要了解如何从Webmock存根返回post变量中显示的数据。

我正在寻找一个具体的示例或半示例来指导我朝着正确的方向前进，而不是寻找其他地方某些文档的建议，因为我将再次在圈子中运行。

Webmock通过标头存储请求：

stub_request(:post, "www.example.com").with(:body => "abc",
  :headers => { 'Content-Length' => 3 })

通过阅读Wikipedia article，您可以在进行一些编码工作后设置Authorization标头，就像其他标头字段一样：

  

Authorization标头的构造如下：[8]

     

用户名和密码组合成一个字符串“username：password”   然后使用RFC2045-MIME变体对结果字符串进行编码   Base64，但不限于76 char / line [9]授权方法   然后在编码的字符串之前放置一个空格，即“Basic”。对于   例如，如果用户代理使用“Aladdin”作为用户名并且“打开”   sesame'作为密码，然后标题形成如下：

     

授权：基本QWxhZGRpbjpvcGVuIHNlc2FtZQ ==

这应该适用于GET和POST。
