还有一个很受欢迎的图书馆，qs。您可以通过以下方式添加:

yarn add qs

然后像这样使用它:

import qs from 'qs'

const array = { a: { b: 'c' } }
const stringified = qs.stringify(array, { encode: false })

console.log(stringified) //-- outputs a[b]=c

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

PHP符号的TypeScript版本(没有URL转义版本)

/**
 * Converts an object into a Cookie-like string.
 * @param toSerialize object or array to be serialized
 * @param prefix used in deep objects to describe the final query parameter
 * @returns ampersand separated key=value pairs
 *
 * Example:
 * ```js
 * serialize({hello:[{world: "nice"}]}); // outputs  "hello[0][world]=nice"
 * ```
 * ---
 * Adapted to TS from a StackOverflow answer https://stackoverflow.com/a/1714899/4537906

const serialize = (toSerialize: unknown = {}, prefix?: string) => {
  const keyValuePairs = [];

  Object.keys(toSerialize).forEach((attribute) => {
    if (Object.prototype.hasOwnProperty.call(toSerialize, attribute)) {
      const key = prefix ? `${prefix}[${attribute}]` : attribute;
      const value = toSerialize[attribute];
      const toBePushed =
        value !== null && typeof value === "object"
          ? serialize(value, key)
          : `${key}=${value}`;
      keyValuePairs.push(toBePushed);
    }
  });

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

以下是已接受答案的CoffeeScript版本。

serialize = (obj, prefix) ->
  str = []
  for p, v of obj
    k = if prefix then prefix + "[" + p + "]" else p
    if typeof v == "object"
      str.push(serialize(v, k))
    else
      str.push(encodeURIComponent(k) + "=" + encodeURIComponent(v))

  str.join("&")

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。
