在Ruby中将String转换为JSON

Question

I have read data online, but it is in a string format. How can I make it so that it returns a JSON object.

Example data read:

text = '{"one":1,"two":2}'

Example conversion:

data = JSON.parse(text).to_json 

But when I do:

puts data.class
#=> String

Answer 1

Omit to_json : it will convert the hash back to json! (JSON -> Hash -> JSON)

require 'json'
text = '{"one":1,"two":2}'
data = JSON.parse(text)  # <--- no `to_json`
# => {"one"=>1, "two"=>2}
data.class
# => Hash
