将对象以参数形式拼接在某个地址后

function splitQueryParams(params) {
  let tempParams = [];
  if (Object.keys(params).length <= 0) return tempParams;

  for (let key in params) {
      tempParams.push(`${key}=${params[key]}`);
  }

  return tempParams.join("&");
}

//  'name=关键字&keyword=哇哈哈&target=搜索'
splitQueryParams({target: '搜索', name: '关键字', keyword: '哇哈哈'})
