导读:我希望能够自动将 JSON对象解析为实例变量.例如,使用此JSON. require 'httparty'json = HTTParty.get('http://api.dribbble.com/players/simplebits') #= {"shots_count":150,"twitter_screen_name":"simplebits","avatar_url":"http://dribbble.com/system/

JSON对象解析为实例变量.例如,使用此JSON.
require 'httparty' json = HTTParty.get('http://api.dribbble.com/players/simplebits') #=> {"shots_count":150,"twitter_screen_name":"simplebits","avatar_url":"http://dribbble.com/system/users/1/avatars/thumb/dancederholm-peek.jpg?1261060245","name":"Dan Cederholm","created_at":"2009/07/07 21:51:22 -0400","location":"Salem,MA","following_count":391,"url":"http://dribbble.com/players/simplebits","draftees_count":104,"id":1,"drafted_by_player_id":null,"followers_count":2214} 我希望能够这样做: json.shots_count 并输出: 150 我怎么可能这样做? 解决方法
你绝对应该使用类似json [“shots_counts”]的东西,但如果你真的需要客观化的哈希,你可以为此创建一个新类:
class ObjectifiedHash def initialize hash @data = hash.inject({}) do |data,(key,value)| value = ObjectifiedHash.new value if value.kind_of? Hash data[key.to_s] = value data end end def method_missing key if @data.key? key.to_s @data[key.to_s] else nil end end end 之后,使用它: ojson = ObjectifiedHash.new(HTTParty.get('http://api.dribbble.com/players/simplebits')) ojson.shots_counts # => 150 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
