Rails Hashie输出

Question

这是我的问题，我从请求中获取变量并将其存储在@response中。

然后我调试响应，调试（@response），并获得此输出：

--- !ruby/hash:Hashie::Mash
results:
- !ruby/hash:Hashie::Mash
  id: '33098557'
  firstName: john
  lastName: star
  relationship: self
  photo: https://foursquare.com/img/blank_boy.png
  tips: !ruby/hash:Hashie::Mash
    count: 0
  lists: !ruby/hash:Hashie::Mash
    groups:
    - !ruby/hash:Hashie::Mash
      type: created
      count: 1
      items: []
  gender: male
  homeCity: mexico
  bio: ''
  contact: !ruby/hash:Hashie::Mash
    email: jhon@hotmail.com
unmatched: !ruby/hash:Hashie::Mash
  email: []

我可以通过输入@ response.results来获得结果，然后对此进行调查：

---
- !ruby/hash:Hashie::Mash
  id: '33098557'
  firstName: john
  lastName: star
  relationship: self
  photo: https://foursquare.com/img/blank_boy.png
  tips: !ruby/hash:Hashie::Mash
    count: 0
  lists: !ruby/hash:Hashie::Mash
    groups:
    - !ruby/hash:Hashie::Mash
      type: created
      count: 1
      items: []
  gender: male
  homeCity: mexico
  bio: ''
  contact: !ruby/hash:Hashie::Mash
    email: jhon@hotmail.com

但我无法获得内部属性，如电子邮件或名字，我如何访问这些属性???

Answer 1

@response是Hashie::Mash的实例，而@response.results是Array的实例，因此您需要访问要接收结果的数组的索引对

@response.results[0].firstName
@response.results[0].contact.email

将分别返回第一个结果的firstName和email的值。您可以遍历响应（如果碰巧有多个，则获取所有结果）

@response.results.each do |result|
  result.firstName
  result.contact.email
end

如果始终只有一个result，您也可以使用Ruby的.first方法

来访问它

@response.results.first.email
