小编use*_*245的帖子

我试过了:

require 'net/http'
require 'json'
require 'pp'
require 'uri'

url = "http://xyz.com"
resp = Net::HTTP.get_response(URI.parse(url))
buffer = resp.body
result = JSON.parse(buffer)
#result.to_hash
    #pp result
puts result  

得到的输出为:

{"id"=>"ABC", "account_id"=>"123", "first_name"=> "PEUS" }

以JSON格式,但我只需要id打印的值为ABC.
