  ## 获取商品id
  例如：某个商品的网页url为 https://item.jd.com/1178879.html ，那么商品id就是 1178879，多个商品id之间用英文逗号分隔

  ## 获取地区id
  在商品页面(例如 https://item.jd.com/1178879.html) 打开开发者工具，选择好收货地址，在 Console 中执行以下 Javascript 代码：

  var el = document.getElementsByClassName("ui-area-text")[0]
  var area_name = el.getAttribute("title")
  var area_id = el.getAttribute("data-id").replace(/-/g, "_")
  console.log(area_name)
  console.log(area_id)
