由于原帖已无法编辑，故本次更新以新贴方式发布
原帖地址：
更新内容：
- 修复
refresh token自动更新access token后无法正常更新share token的 BUG
之前没有 rt 所以根本没试过，这两天终于也是三级了可以自己测试了
-
将反向代理集成至单个worker，不再需要部署单独反代worker
-
share token过期或输入错误的username后，自动跳转至新增的基于username的登陆界面（仍然支持原来的链接直达，只是新增了支持的登陆方式）
注：由于自定义反代后无法实现st过期检测，故此次直接使用单个worker同时集成流量代理和token管理功能，删去了自定义反向代理地址的配置
更新界面预览：
-
st过期后自动弹出
-
username错误
更新方式：
在原帖配置的基础上，将worker代码替换为如下代码即可

event.respondWith(handleRequest(event.request))
