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('&');
    }

ES6解决方案用于JavaScript对象的查询字符串编码

const params = {
  a: 1,
  b: 'query stringify',
  c: null,
  d: undefined,
  f: '',
  g: { foo: 1, bar: 2 },
  h: ['Winterfell', 'Westeros', 'Braavos'],
  i: { first: { second: { third: 3 }}}
}

static toQueryString(params = {}, prefix) {
  const query = Object.keys(params).map((k) => {
    let key = k;
    const value = params[key];

    if (!value && (value === null || value === undefined || isNaN(value))) {
      value = '';
    }

    switch (params.constructor) {
      case Array:
        key = `${prefix}[]`;
        break;
      case Object:
        key = (prefix ? `${prefix}[${key}]` : key);
        break;
    }

    if (typeof value === 'object') {
      return this.toQueryString(value, key); // for nested objects
    }

    return `${key}=${encodeURIComponent(value)}`;
  });

  return query.join('&');
}

toQueryString (params)

"a=1&b=query%20stringify&c=&d=&f=&g[foo]=1&g[bar]=2&h[]=Winterfell&h[]=Westeros&h[]=Braavos&i[first][second][third]=3"

下面是Object.entries的简洁递归版本。它处理任意嵌套的数组，但不处理嵌套的对象。它还会删除空元素:

const format = (k,v) => v !== null ? `${k}=${encodeURIComponent(v)}` : ''

const to_qs = (obj) => {
    return [].concat(...Object.entries(obj)
                       .map(([k,v]) => Array.isArray(v) 
                          ? v.map(arr => to_qs({[k]:arr})) 
                          : format(k,v)))
           .filter(x => x)
           .join('&');
}

例如:

let json = { 
    a: [1, 2, 3],
    b: [],              // omit b
    c: 1,
    d: "test&encoding", // uriencode
    e: [[4,5],[6,7]],   // flatten this
    f: null,            // omit nulls
    g: 0
};

let qs = to_qs(json)

=> "a=1&a=2&a=3&c=1&d=test%26encoding&e=4&e=5&e=6&e=7&g=0"

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。
