版本：2.2312

[General]
force-http-engine-hosts = %APPEND% aliyun.example.com:0

[Script]
阿里云盘 = type=http-request,pattern=^http:\/\/aliyun\.example\.com,requires-body=1,script-path=https://raw.githubusercontent.com/githubdulong/Script/master/ali.js,max-size=0,debug=0

作者：@小白脸 @Chosen Ome
使用方法： 
添加Synoogy协议，账号随便填，密码填cookie 获取ck的方法如下
阿里云Token获取地址(需要用阿里云盘扫描alist的二维码获得)[ https://alist-doc.nn.ci/docs/driver/aliyundrive ]
