需要对嵌套的 json 对象进行排序 像上面那个一样吗？

Answer 1

现在你可能已经得到答案了，

function rFun(obj, newObj){
    Object.keys(obj).sort().forEach(key=>{
        if(typeof obj[key] === 'object'){
            newObj[key] = {};
            newObj[key] = rFun(obj[key], newObj[key]);
        } else {
            newObj[key] = obj[key];
        }
    });
    return newObj;
}

JSON.stringify(rFun(dataSource, {}));

它是按 ASCII 排序的，对于不区分大小写的情况，你必须编写自定义排序。
