OneDrive CF Worker 加速

提示

使用 CF 后下载速度不一定比原来快，这个自行测试。一般来说世纪互联版无需使用此方式。

Workers 代码修改

方式一（仅支持单线程下载）

addEventListener("fetch",event => {
    let url = new URL(event.request.url);
    // 随便去 "OneDrive 里找个文件下载" 或 "先不写反代域名绑定 OneDrive 到 ZFile，再找个文件下载"，去浏览器下载记录中找到下载链接，将域名部分写入到这里，不带协议头
    // 如 https://xxx-my.sharepoint.com/personal/xxx_xxx_onmicrosoft_com/_layouts/15/download.aspx?UniqueId=xxx&SourceUrl=xxx
    // 则填写 xxx-my.sharepoint.com
    url.hostname ="youdomain.com";

    let request = new Request(url,event.request);
    event.respondWith(
        fetch(request,{
            headers:{
                 // 和上面的域名对应，只是在前面加上了 https://, 如 https://xxx-my.sharepoint.com
                'Referer':'https://youdomain.com/',
                'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.100 Safari/537.36'
            }
        })
    )
});

方式二（支持多线程下载）

提示

此方法为 2021.09.18 新增，支持多线程下载，原作者链接为：https://blog.bbimax.com/archives/92

    // 随便去 "OneDrive 里找个文件下载" 或 "先不写反代域名绑定 OneDrive 到 ZFile，再找个文件下载"，去浏览器下载记录中找到下载链接，将域名部分写入到这里，不带协议头
// 如 https:/abc-my.sharepoint.com/personal/xxx_xxx_onmicrosoft_com/_layouts/15/download.aspx?UniqueId=xxx&SourceUrl=xxx
// 则填写 abc-my.sharepoint.com
const upstream = '*-my.sharepoint.com'

// 一般情况和上面的一样，只是这个是移动端下载使用的域名.
const upstream_mobile = '*-my.sharepoint.com'

// 下面的配置都不用动
const upstream_path = '/'

// 禁止访问的国家代码，可参考：https://wenku.baidu.com/aggs/bad9979951e79b89680226aa.html

添加到 ZFILE

测试下载

然后去 ZFile 首页下载文件，查看下载域名就可以看到已经变成了 Cloudflare Workers 的域名了。

提示

CF 分配的域名可能是被墙的，导致无法下载，可在 Cloudflare Workers 中绑定自定义域名解决。
