从Ruby中的JSON获取特定的键值 [英] Get a particular key value from json in ruby

问题描述

[ 
"KEY1":{"SUB_KEY1" : "VALUE1","SUB_KEY2" : "VALUE2"},
"KEY2":{"SUB_KEY1" : "VALUE1","SUB_KEY2" : "VALUE2"}
]

以上是我的json对象，它是作为响应而来的.

The above is my json object which is coming as a response.

如何在Ruby on Rails中获得KEY1的SUB_KEY1和KEY2的SUB_KEY1?

How do I get SUB_KEY1 of KEY1 and SUB_KEY1 of KEY2 in Ruby on Rails?

谢谢.

推荐答案

parsed_json = ActiveSupport::JSON.decode(your_json_string)

会将您的字符串解析为

 [{"KEY1"=>{"SUB_KEY1"=>"VALUE1", "SUB_KEY2"=>"VALUE2"}}, {"KEY2"=>{"SUB_KEY1"=>"VALUE1", "SUB_KEY2"=>"VALUE2"}}]

您应该可以使用 parsed_json[1]["KEY2"]["SUB_KEY1"]
