我为此写了一个包:object-query-string:)

它支持嵌套对象、数组、自定义编码函数等。它是轻量级的，不支持jquery。

// TypeScript
import { queryString } from 'object-query-string';

// Node.js
const { queryString } = require("object-query-string");

const query = queryString({
    filter: {
        brands: ["Audi"],
        models: ["A4", "A6", "A8"],
        accidentFree: true
    },
    sort: 'mileage'
});

返回

filter[brands][]=Audi&filter[models][]=A4&filter[models][]=A6&filter[models][]=A8&filter[accidentFree]=true&sort=milage

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

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('&')
);

如果你想将整个对象作为一个参数传递，例如，?filter={param1: "val1"， param2: "val2"}:

const serializeObject = (obj) => {
  let objStr = JSON.stringify(obj);

  objStr = objStr.replace(/\{/g, encodeURIComponent("{"));
  objStr = objStr.replace(/}/g, encodeURIComponent("}"));
  objStr = objStr.replace(/:/g, encodeURIComponent(":"));

  return objStr;
};

let res = serializeObject({param1: "val1", param2: "val2"});
console.log("serializeObject:", res); //%7B"param1"%3A"val1","param2"%3A"val2"%7D
console.log("serializeObject-decoded:", decodeURIComponent(res)); //{"param1":"val1","param2":"val2"}

下面是ES6中的一行代码:

Object.keys(obj).map(k => `${encodeURIComponent(k)}=${encodeURIComponent(obj[k])}`).join('&');
