如何迭代此JSON对象？

Question

这是一个response在HTTP POST请求中返回的对象:

res.body
=> "{\"id\":\"a3adasfaf3\",\"url\":\"https://someurl/a3adasfaf3\",\"created\":\"2016-05-30T07:00:58Z\",\"modified\":\"2016-05-30T07:00:58Z\",\"files_hash\":\"cljhlk2j3l2kj34hlke18\",\"language\":\"ruby\",\"title\":\"Some weird hello world message\",\"public\":false,\"owner\":\"kljhlk2jh34lk2jh4l2kj3h4l2kj4h23l4kjh2l4k\",\"files\":[{\"name\":\"Some-weird-hello-world-message.rb\",\"content\":\"puts \\\"Some weird hello world message.\\\"\\r\\n\"}]}"

我试图退出,并翻译它的各种属性response.例如,至少id和url.

我该怎么做呢？

为了记录,我使用Ruby的NET/HTTP std lib发送POST请求并获取此响应.

对于奖励积分,我想要的只是存储在每个属性中的实际值(即实际值id(只是一个字符串)和一个url(这是一个典型的URL).所以,如果你包括我如何访问该属性然后消毒它同时会很棒.

使用JSON.parse来解析响应.

response = "{\"id\":\"a3adasfaf3\",\"url\":\"https://someurl/a3adasfaf3\",\"created\":\"2016-05-30T07:00:58Z\",\"modified\":\"2016-05-30T07:00:58Z\",\"files_hash\":\"cljhlk2j3l2kj34hlke18\",\"language\":\"ruby\",\"title\":\"Some weird hello world message\",\"public\":false,\"owner\":\"kljhlk2jh34lk2jh4l2kj3h4l2kj4h23l4kjh2l4k\",\"files\":[{\"name\":\"Some-weird-hello-world-message.rb\",\"content\":\"puts \\\"Some weird hello world message.\\\"\\r\\n\"}]}"

require 'json'

JSON.parse response
# output:
# {"id"=>"a3adasfaf3", "url"=>"https://someurl/a3adasfaf3", "created"=>"2016-05-30T07:00:58Z", "modified"=>"2016-05-30T07:00:58Z", "files_hash"=>"cljhlk2j3l2kj34hlke18", "language"=>"ruby", "title"=>"Some weird hello world message", "public"=>false, "owner"=>"kljhlk2jh34lk2jh4l2kj3h4l2kj4h23l4kjh2l4k", "files"=>[{"name"=>"Some-weird-hello-world-message.rb", "content"=>"puts \"Some weird hello world message.\"\r\n"}]}

response["name"] # => a3adasfaf3
