可以将具有未定义属性的对象传递给此函数。如果属性存在，它将被转换为查询字符串并返回查询字符串。

函数convertToQueryString(props) { const objQueryString ={…道具}; for (objQueryString中的const键){ If (!key) { 删除objQueryString(例子); ｝ ｝ const params = JSON.stringify(objQueryString); Const qs =参数 .replace (/[/''""{}]/ 克,”) .replace (/ [:] / g, ' = ') .replace (/, / g, ' & '); console.log (qs) 返回qs; ｝ convertToQueryString({order: undefined, limit: 5, page: 1})

只需使用以下方法:

encodeURIComponent(JSON.stringify(obj))

// elastic search example let story ={ "query": { "bool": { "must": [ { "term": { "revision.published": 0, } }, { "term": { "credits.properties.by.properties.name": "Michael Guild" } }, { "nested": { "path": "taxonomy.sections", "query": { "bool": { "must": [ { "term": { "taxonomy.sections._id": "/science" } }, { "term": { "taxonomy.sections._website": "staging" } } ] } } } } ] } } } const whateva = encodeURIComponent(JSON.stringify(story)) console.log(whateva)

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("&")

这里有一个简单的答案，在转换过程中同时处理字符串和数组。

jsonToQueryString: function (data) {
        return Object.keys(data).map((key) => {
            if (Array.isArray(data[key])) {
                return (`${encodeURIComponent(key)}=${data[key].map((item) => encodeURIComponent(item)).join('%2C')}`);
            }
            return(`${encodeURIComponent(key)}=${encodeURIComponent(data[key])}`);
        }).join('&');
    }

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

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。
