cloudreve搭建网盘+onedrive反代加速

昨天突然想起来自己还有个E5订阅的5T OneDrive还在吃灰
作为一个合格的mjj肯定要本着不浪费的原则让它动起来啦

然后又无意间看到了两篇帖子,第一篇帖子
Cloudreve新版本增加了onedrive反代
第二篇OneDrive workers反代代码

然后诸位mjj都懂,我们的网盘搭建就有了个大体思路。

cloudreve搭建方法就不赘述了。
反正是go语言编译出来的,
官方文档也很齐全(有手 就行 )
怎么对接onedrive也不说了

关键在于OneDrive的反代及加速

贴上代码地址:https://github.com/EtherDream/jsproxy/blob/master/cf-worker/index.js (感谢Lemon0大佬)
附图:

把你的onedrive直链https://*-my.sharepoint.com/地址替换到代码中标注地址。
最后把workers部署发布然后绑定一个通过cname接入的域名。

举个例子:
我用萌精灵 把*.com 解析到 1.0.0.1 (这里ip可以随便填,等会儿会加入workers路由),再通过cname接入到国内解析平台。
在dns运营商自选ip上,我选用了cf2dns的项目(免费版本会延迟1天的数据,收费版本1快1000次),
通过解析后dnspod或者阿里dns后,大部分地方的速度都能拉起来(有些玄学的地方是在没办法),
需要注意的是:cf2dns是作者部署在国内的机器选取质量上佳的ip,但机器有限,选取的IP单一,所以不能以一概全。
最后workers绑定域名。

附上cloudreve的设置
