最近OFB(onedrive for business)速度越来越慢了,虽然用idm这类多线程下载器也可以起一定的加速作用,但并不是每个人都有时间去研究。
网上搜到的也都是去注册应用,填写应用程序ID和客户端Key,实现展示+分享+下载文件。
但我只是需要下载啊
折腾半天,也希望后人能少走些弯路吧;-)
本实例的特点💡:
无需创建应用,无需管理员同意,即使学校账号没有开放API权限也可以使用。
仅支持单线程下载,且IDM不支持断点续传。(但浏览器可以)
IP选的好可大幅度提升大多数浏览器的下载速度,适合小白使用。
准备:
1.一个Cloudflare账号
2.一个已接入Cloudflare的域名(本实例使用sunbangyan.cn下的子域名1drv.sunbangyan.cn)
3.一个速度较快的自选IP(本实例使用104.16.127.166)
4.你的sharepoint组织名称(本实例为sunbangyan)
A.首先,打开 dash.cloudflare.com,找到左侧的Workers,打开它。
B.然后,轻点右方的“创建应用程序”,然后点下方的“创建woker”
C.然后点击“编辑代码”
D.复制下面的内容替换掉编辑器里面的内容

E.然后回到上面,修改ASSET_URL这一行
(本示例改为https://test-my.sharepoint.com)
F.最后“保存并部署”,从左上角退出。
G.然后打开“触发器”,先在“自定义域”中,添加要作为反代服务的域名,等待3~5分钟后刷新页面,直到“证书”列显示为“有效”。
在下方点击“添加路由”,同样输入反代域名,但这里注意一点,最后一定要
H.打开你的域名dns页,手动添加一条A记录解析,解析到你的自选IP。并且点掉橙色云朵,改为“仅限DNS”。
保存你的解析,至此,完成✅!
