本周又是低产的一周,但整活儿记录还是要有。
一种通过Cloudflare Workers反代SharePoint进行加速的方法
不多BB,上代码
// 替换成你OneDrive的网址
const upstream = '*-my.sharepoint.com'
// 替换成你OneDrive的网址
const upstream_mobile = '*-my.sharepoint.com'
// 下面的配置都不用动

StepⅠ:使用方法:
注册cloudflare账号:https://dash.cloudflare.com/sign-up
有账号可以直接登陆
粘贴并修改好代码后,点击“保存并部署”,即可上线了
这里需要根据自己的SharePoint网址替换其中的*号,例如我的存储空间就是bbimax-my.sharepoint.com,将*号替换为bbimax即可。
保存并部署后访问这个网页,会出现如下显示:
但通过这个地址,我们已经使用cloudflare成功反代了SharePoint的流量。
StepⅡ:应用举例:
Cloudreve V3.2.1版本加入了OneDrive反代功能,在对接存储时把反代链接填上即可。
StepⅢ:自定义域名
如果嫌自动分配的域名不美观的话,可以自定义域名,前提是你要有个域名,并完成cloudflare的接入。
进入你要添加域名的主域,点击“添加记录”
点击上方的workers,点击添加路由
如图所示进行填写,注意后面的斜杠与星号必须要有,worker指向我们刚才创建的这个:
点击保存后,稍等几分钟,解析成功就可以使用了。
StepⅣ:效果验证
测试环境:中国电信500mbps家庭宽带,其实大陆的SharePoint国际版下载速度从2018年开始就一直不太好,时常处于“带宽紧张”的状态(不排除微软自行限速的可能)。从图中我们可以看出,经过反代后,单线程下载速度已经取得了明显的提升,毕竟cloudflare的反代能力有限,具体下载速度还要取决于国际带宽情况。
使用IDM之类的多线程下载工具,也许可以获得更好的效果。
