如果你使用的是NodeJS 13.1或更高版本，你可以使用本地querystring模块来解析查询字符串。

const qs = require('querystring');
let str = qs.stringify(obj)

Object.toparams = function ObjecttoParams(obj) 
{
  var p = [];
  for (var key in obj) 
  {
    p.push(key + '=' + encodeURIComponent(obj[key]));
  }
  return p.join('&');
};

如果你需要一个递归函数来根据给定的对象生成正确的URL参数，试试我的Coffee-Script。

@toParams = (params) ->
    pairs = []
    do proc = (object=params, prefix=null) ->
      for own key, value of object
        if value instanceof Array
          for el, i in value
            proc(el, if prefix? then "#{prefix}[#{key}][]" else "#{key}[]")
        else if value instanceof Object
          if prefix?
            prefix += "[#{key}]"
          else
            prefix = key
          proc(value, prefix)
        else
          pairs.push(if prefix? then "#{prefix}[#{key}]=#{value}" else "#{key}=#{value}")
    pairs.join('&')

或者JavaScript编译…

toParams = function(params) {
  var pairs, proc;
  pairs = [];
  (proc = function(object, prefix) {
    var el, i, key, value, _results;
    if (object == null) object = params;
    if (prefix == null) prefix = null;
    _results = [];
    for (key in object) {
      if (!__hasProp.call(object, key)) continue;
      value = object[key];
      if (value instanceof Array) {
        _results.push((function() {
          var _len, _results2;
          _results2 = [];
          for (i = 0, _len = value.length; i < _len; i++) {
            el = value[i];
            _results2.push(proc(el, prefix != null ? "" + prefix + "[" + key + "][]" : "" + key + "[]"));
          }
          return _results2;
        })());
      } else if (value instanceof Object) {
        if (prefix != null) {
          prefix += "[" + key + "]";
        } else {
          prefix = key;
        }
        _results.push(proc(value, prefix));
      } else {
        _results.push(pairs.push(prefix != null ? "" + prefix + "[" + key + "]=" + value : "" + key + "=" + value));
      }
    }
    return _results;
  })();
  return pairs.join('&');
};

这将构造如下的字符串:

toParams({a: 'one', b: 'two', c: {x: 'eight', y: ['g','h','j'], z: {asdf: 'fdsa'}}})

"a=one&b=two&c[x]=eight&c[y][0]=g&c[y][1]=h&c[y][2]=j&c[y][z][asdf]=fdsa"

使用Axios和无限深度:

<pre> <style> textarea { width: 80%; margin-bottom: 20px; } label { font-size: 18px; font-weight: bold; } </style> <label>URI</label> <textarea id="uri" rows="7"></textarea> <label>All Defaults (Bonus): </label> <textarea id="defaults" rows="20"></textarea> </pre> <script src="https://unpkg.com/axios/dist/axios.min.js"></script> <script> const instance = axios.create({ baseUrl: 'http://my-api-server', url: '/user' }) const uri = instance.getUri({ params: { id: '1234', favFruits: [ 'banana', 'apple', 'strawberry' ], carConfig: { items: ['keys', 'laptop'], type: 'sedan', other: { music: ['on', 'off', { foo: 'bar' }] } } } }) const defaults = JSON.stringify(instance.defaults, null, 2) document.getElementById('uri').value = uri document.getElementById('defaults').value = defaults </script>

祝你好运…

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

试试这个…这也适用于嵌套对象。

let my_obj = {'single':'this is single', 'nested':['child1','child2']};

((o)=>{ return Object.keys(o).map(function(key){ let ret=[]; if(Array.isArray(o[key])){ o[key].forEach((item)=>{ ret.push(`${key}[]=${encodeURIComponent(item)}`); }); }else{ ret.push(`${key}=${encodeURIComponent(o[key])}`); } return ret.join("&");  }).join("&"); })(my_obj);
