urlencoded类型的字符串和json对象的转换

import qs from 'querystring'

let obj = {name:'tom',age:18}
console.log(qs.stringify(obj)) // "name='tom'&age=18"

let str = 'carName=奔驰&price=199'
console.log(qs.parse(str))  //{carMa,e:'奔驰',price:"199"}

urlencoded类型的字符串转json对象：qs.parse()

json对象转urlencoded类型的字符串:  qs.stringfy()
