我的实现编码一个对象作为一个查询字符串，使用减少:

export const encodeAsQueryString = (params) => (
  Object.keys(params).reduce((acc, key)=>(
    params.hasOwnProperty(key) ? (
      [...acc, encodeURIComponent(key) + '=' + encodeURIComponent(params[key])]
    ) : acc
  ), []).join('&')
);

    ) : acc

);

对于TS

const convertQueryToString = (data: { [x: string]: any }): string => { const serialize = (obj: { [x: string]: any }, prefix?: string): string => { const str = []; let p; for (p in obj) { if (obj.hasOwnProperty(p)) { const k = prefix ? `${prefix}[${p}]` : p; const v = obj[p]; str.push( v !== null && typeof v === 'object' ? serialize(v, k) : `${encodeURIComponent(k)}=${encodeURIComponent(v)}` ); } } return str.join('&'); }; return serialize(data); };

如果有很多嵌套对象，前面的答案就不起作用了。

相反，你可以从jquery-param/jquery-param.js中选择函数参数。这对我来说非常有效!

    var param = function (a) {
    var s = [], rbracket = /\[\]$/,
        isArray = function (obj) {
            return Object.prototype.toString.call(obj) === '[object Array]';
        }, add = function (k, v) {
            v = typeof v === 'function' ? v() : v === null ? '' : v === undefined ? '' : v;
            s[s.length] = encodeURIComponent(k) + '=' + encodeURIComponent(v);
        }, buildParams = function (prefix, obj) {
            var i, len, key;

            if (prefix) {
                if (isArray(obj)) {
                    for (i = 0, len = obj.length; i < len; i++) {
                        if (rbracket.test(prefix)) {
                            add(prefix, obj[i]);
                        } else {
                            buildParams(prefix + '[' + (typeof obj[i] === 'object' ? i : '') + ']', obj[i]);
                        }
                    }
                } else if (obj && String(obj) === '[object Object]') {
                    for (key in obj) {
                        buildParams(prefix + '[' + key + ']', obj[key]);
                    }
                } else {
                    add(prefix, obj);
                }
            } else if (isArray(obj)) {
                for (i = 0, len = obj.length; i < len; i++) {
                    add(obj[i].name, obj[i].value);
                }
            } else {
                for (key in obj) {
                    buildParams(key, obj[key]);
                }
            }
            return s;
        };

    return buildParams('', a).join('&').replace(/%20/g, '+');
};

是这样的:

Serialize =函数(obj) { Var STR = []; For (var p in obj) if (obj.hasOwnProperty(p)) { str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]))); ｝ 返回str.join(“&”); ｝ console.log(序列化({ Foo:“你好”， 栏:“100%” })); / / foo =你好% 20 there&bar 25 = 100%

它还转换递归对象(使用PHP“数组”符号表示查询字符串):

serialize = function(obj, prefix) { var str = [], p; for (p in obj) { if (obj.hasOwnProperty(p)) { var k = prefix ? prefix + "[" + p + "]" : p, v = obj[p]; str.push((v !== null && typeof v === "object") ? serialize(v, k) : encodeURIComponent(k) + "=" + encodeURIComponent(v)); } } return str.join("&"); } console.log(serialize({ foo: "hi there", bar: { blah: 123, quux: [1, 2, 3] } })); // foo=hi%20there&bar%5Bblah%5D=123&bar%5Bquux%5D%5B0%5D=1&bar%5Bquux%5D%5B1%5D=2&bar%5Bquux%5D%5B2%5D=3

只使用URLSearchParams，这适用于当前所有浏览器

new URLSearchParams(object).toString()
