  // 获取url中search参数
let getSearch = function (url) {
    let matched = /^(?:https?:\/\/[^?]*\?)(.*)/gi.exec(url)
    return matched ? matched[1] : ''
  }

// 递归函数，循环匹配search
let searchFn = function (search, query) {
  if (search) {
    let matched = /(\w+)=(\w*)/g.exec(search)
    if (matched) {
      query[matched[1]] = decodeURIComponent(matched[2])
      searchFn(search.slice(matched.index + matched[0].length), query)
    }
  }
}
let parseUrl = function (url) {
  let query = {}
  searchFn(getSearch(url), query)
  return query
}

let url = 'http://localhost:3009/h5/test?recordID=161851&order=2'
console.log(parseUrl(url)) // => { recordID: '161851', order: '2' }
