Ruby如何解析这个响应以将用户的工作经验存储在数据库中

我正在使用OmniAuth LinkedIn来验证和存储用户信息。这是i YAML:：dump（response.env['omniauth.auth'].extra.raw_info）时显示的输出

res = YAML::parse(response)

我的问题是：如何解析这个响应来存储用户的工作经验（列出的几家公司）和用户教育

这是我的app.rb文件中的内容，该文件基于sinatra

%w(get post).each do |method|
    send(method, "/auth/:provider/callback") do

        response =  (request.env['omniauth.auth']).extra.raw_info
        "<pre>" + YAML::dump(response) + "</pre>" + "<br /><br />" 
    end
end

%w（get post）。每个do |方法|
发送（方法“/auth/：provider/callback”）执行
response=（request.env['omniauth.auth']）。extra.raw\u info
res = YAML::parse(response)

“”+YAML:：转储（响应）+“”+“

”
结束
结束

我会尝试以下方法：

puts res.inspect # show the nested bits via  stdout
                 # or through some other logging

然后您可以这样做：

res["lastname"] # -> Iglesias
res["educations]["id"] # -> 154175914
res["location"]["country"]...

没有ominauth我不能确定测试，但看起来您可以像这样访问元素

您可能想尝试一些解决方案，以便在sinatra周围获得调试器

我是ruby的新手，这让我发疯。我可以访问电子邮件地址、id和所有其他第一层属性，但我根本不知道如何迭代这些嵌套实体以提取我想要存储的所有信息，如工作经验等。请尝试YAML:：parse（…）在yaml数据上，然后进行检查。您可能希望在irb中尝试进行检查。检查上面的代码块，我在我的method@PaulRubel-我将如何做你推荐的我尝试过的事情？提前感谢你的帮助。
