如何解决错误ReferenceError:nodejs coffeescript中未定义json_decode

Question

我想检索我帖子的facebook点赞。我已经写了代码，但它显示错误。

    facebookDataUrl = "http://graph.facebook.com/yourstory.com/2016/04/shotpitch-startup-trended-product-hunt/"
    console.log facebookDataUrl     
    data = Http::curl(facebookDataUrl)
fbshares = json_decode(data, true)
fbsharescnt = fbshares['shares']
console.log fbsharescnt

上面的代码显示错误

fbshares = json_decode(data, true);
         ^

ReferenceError:json_decode未定义

使用JSON.parse()。

get = require 'http-get-shim'                                            
url = 'http://graph.facebook.com/yourstory.com/2016/04/shotpitch-startup-trended-product-hunt/'                                                   
get url, (er, resp, body) ->                                             
  data = JSON.parse body                                                 
  console.log data
