You can simply use JSON.parse.
node.js is built on V8, which provides the global object JSON[docs]. The definition of the JSON object is part of the ECMAScript 5 specification.
JSON.stringify(obj)将JS对象转为字符串。
var json = { aa: [‘sdddssd‘],
bb: [ ‘892394829342394792399‘, ‘23894723984729374932874‘ ],
cc: [‘11111111111111‘] }
=> var string = JSON.stringify(json)
string:
{"aa":["sdddssd"],"bb":["892394829342394792399","23894723984729374932874"],"cc":["11111111111111"]}
