如果您需要一个递归函数，该函数将根据给定的对象生成正确的URL参数，请尝试使用我的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JavaScript已编译...

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"

var obj = {
  param1: 'something',
  param2: 'somethingelse',
  param3: 'another'
}
obj['param4'] = 'yetanother';
var str = jQuery.param(obj);
alert(str);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

var str = '';

for( var name in obj ) {
    str += (name + '=' + obj[name] + '&');
}

str = str.slice(0,-1);

var kvToParam = R.mapObjIndexed((val, key) => {
  return '&' + key + '=' + encodeURIComponent(val);
});

var objToParams = R.compose(
  R.replace(/^&/, '?'),
  R.join(''),
  R.values,
  kvToParam
);

var o = {
  username: 'sloughfeg9',
  password: 'traveller'
};

console.log(objToParams(o));

<script src="https://cdnjs.cloudflare.com/ajax/libs/ramda/0.22.1/ramda.min.js"></script>

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

 function objToQuery(obj){
  let str = objToParams(obj,'');
  return str.slice(0, str.length);
}
function   objToParams(obj, subobj){
  let str = "";

   for (let key in obj) {
     if(typeof(obj[key]) === 'object') {
       if(subobj){
         str += objToParams(obj[key], `${subobj}[${key}]`);
       } else {
         str += objToParams(obj[key], `[${key}]`);
       }

     } else {
       if(subobj){
         str += `${key}${subobj}=${obj[key]}&`;
       }else{
         str += `${key}=${obj[key]}&`;
       }
     }
   }
   return str;
 }

const queryString = require('query-string');

querystring.stringify({ foo: 'bar', baz: ['qux', 'quux'], corge: '' });
// Returns 'foo=bar&baz=qux&baz=quux&corge='

const obj = { id: 1, name: 'Neel' };
let str = '';
str = Object.entries(obj).map(([key, val]) => `${key}=${val}`).join('&');
console.log(str);
