我对JSON stringfier进行了比较，结果如下:

其中最短的是URL对象表示法。

看起来好一点

objectToQueryString(obj, prefix) {
    return Object.keys(obj).map(objKey => {
        if (obj.hasOwnProperty(objKey)) {
            const key = prefix ? `${prefix}[${objKey}]` : objKey;
            const value = obj[objKey];

            return typeof value === "object" ?
                this.objectToQueryString(value, key) :
                `${encodeURIComponent(key)}=${encodeURIComponent(value)}`;
        }

        return null;
    }).join("&");
}

使用Node.js v6.6.3

const querystring = require('querystring')

const obj = {
  foo: 'bar',
  baz: 'tor'
}

let result = querystring.stringify(obj)
// foo=bar&baz=tor

参考:查询字符串

在ES7中，你可以用一行写:

const serialize = (obj) => (Object.entries(obj).map(i => [i[0], encodeURIComponent(i[1])].join('=')).join('&'))

我有一个更简单的解决方案，它不使用任何第三方库，并且已经易于在任何具有“Object”的浏览器中使用。键”(也就是所有现代浏览器+ edge + ie):

In ES5

function(a){
    if( typeof(a) !== 'object' ) 
        return '';
    return `?${Object.keys(a).map(k=>`${k}=${a[k]}`).join('&')}`;
}

在胡

function(a){
    if( typeof(a) !== 'object' ) 
        return '';
    return '?' + Object.keys(a).map(function(k){ return k + '=' + a[k] }).join('&');
}

Ramda:

    R.pipe(R.toPairs, R.map(R.join('=')), R.join('&'))({a: 'b', b: 'a'})
