将json转换为ruby hash [英] Convert json to ruby hash

问题描述

  @value = {val：test， val1：test1，val2：test2} 
  

我想通过它循环在Ruby中获取键值对。当我使用 @each 时，它不会遍历该对象，因为它不在ruby哈希表中：

  @value = {val=>test，val1=>test1，val2=>test2} 
  

如何将上述JSON对象转换为Ruby哈希？

解决方案

下面的代码片段如何？

  require'json'
 value ='{val：test，val1：test1，val2：test2}'
 puts JSON.parse （值）＃=> {val=>test，val1=>test1，val2=>test2} 
  

I have a JSON object holding the following value:

@value = {"val":"test","val1":"test1","val2":"test2"}

I want to loop through it in Ruby to get the key value pairs. When I use @each, it doesn't iterate through the object because it is not in the ruby hash form:

@value = {"val"=>"test","val1"=>"test1","val2"=>"test2"}

How can I convert the above JSON object to Ruby hash?

解决方案

What about the following snippet?

require 'json'
value = '{"val":"test","val1":"test1","val2":"test2"}'
puts JSON.parse(value) # => {"val"=>"test","val1"=>"test1","val2"=>"test2"}
