字符串与JSON互转

JSON 转 字符串

let obj={
    name:'ww';
    age:22;
    sex:'女';
}
let str=JSON.stringify(obj); //{'name':'ww',age:22,sex:'女'}
console.log(typeof string,string);   // string{'name':'ww',age:22,sex:'女'} 

字符串 转 JSON

let obj={
    name:'ww';
    age:22;
    sex:'女';
}
let obj1=JSON.parse(string);
console.log(typeof obj1,obj);   // object{'name':'ww',age:22,sex:'女'} 

字符串与JSON 的互换：JSON——字符串：JSON.stringify ; 字符串——JSON：JSON.parse
