如何使用VCR和Webmock来存根具有基本权限的post请求

免责声明:我是api新手，花了一周时间试图解决这个看似简单的问题，我已经完全迷失了方向。

我有代码与Github的API交互，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。

下面是方法的代码:

def self.create(属性)

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

所有这一切所做的是使实际的POST请求具有给定的某些属性，并将发布的信息存储到一个名为post的变量，然后将其作为属性传递给另一个方法#parse_response_from。这个#parse_response_from方法是我想测试的，但我无法理解我的生活如何用Webmock和VCR模拟post属性。

这是post变量在生产中的样子，我需要模仿:

基本上，我真正需要的是从这个散列中传递给#parse_response_from方法的几个变量。我现在测试的方式只是将某些静态键/值对存储到before块中并测试该代码。看一下:

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

我如何使用Webmock的stub_request存根并将其传递到VCR磁带中?我已经看到了很多关于存根GET的例子，但是我不明白如何为POST使用Webmock。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。

我正在寻找一个特定的例子或半例子来指导我在正确的方向上，而不是在其他地方寻找一些文档的建议，因为我只是在兜圈子。

Webmock存根请求这样:

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

似乎从阅读维基百科的文章，你可以设置Authorization头像其他头字段，经过一点编码工作:

授权头的构造如下:[8]
用户名和密码组合成字符串" Username:password"的RFC2045-MIME变体对生成的字符串进行编码Base64，除不限于76 char/line外[9]的授权方法一个空间是。然后将"Basic"放在编码字符串之前。为例如，如果用户代理使用'Aladdin'作为用户名和'open '
授权:Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
