/* 
  参考了即刻图床开源的阿里接口 https://jike.info/topic/36748
  需要使用美国等地访问 https://www.aliexpress.com/ 并使用第三方直接注册和登录，比如谷歌，如果访问地异常则不会出现第三方登录
  该模块需要阿里国际账号，虽然不需要实名、可以随便注册但需要Cookie。有效期不清楚，有点像一个月。
  这个试验我放在了KV库理论上也可以用D1库，不用Env直接装载是因为Cookie有点长，大概3KB，而Env最大就5KB好像（对于免费用户）
  你需要创建和绑定名为 WORKER_IMGBED 的库，其中新建 K 字段，名为 ali_express_cookie 然后在V中复制进去浏览器F12得到的完整Cookie即可
