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
const upstream_path = '/'
const blocked_region = ['KP', 'SY', 'PK', 'CU']
const blocked_ip_address = ['0.0.0.0', '127.0.0.1']
const https = true
const disable_cache = false
const replace_dict = {
'$upstream': '$custom_domain',
'//sunpma.com': ''
}
addEventListener('fetch', event => {
event.respondWith(fetchAndApply(event.request));
})
async function fetchAndApply(request) {
const region = request.headers.get('cf-ipcountry').toUpperCase();
const ip_address = request.headers.get('cf-connecting-ip');
const user_agent = request.headers.get('user-agent');
let response = null;
let url = new URL(request.url);
let url_hostname = url.hostname;
if (https == true) {
url.protocol = 'https:';
} else {
url.protocol = 'http:';
}
if (await device_status(user_agent)) {
var upstream_domain = upstream;
} else {
var upstream_domain = upstream_mobile;
}
url.host = upstream_domain;
if (url.pathname == '/') {
url.pathname = upstream_path;
} else {
url.pathname = upstream_path + url.pathname;
}
if (blocked_region.includes(region)) {
response = new Response('Access denied: WorkersProxy is not available in your region yet.', {
status: 403
});
} else if (blocked_ip_address.includes(ip_address)) {
response = new Response('Access denied: Your IP address is blocked by WorkersProxy.', {
status: 403
});
} else {
let method = request.method;
let request_headers = request.headers;
let new_request_headers = new Headers(request_headers);
new_request_headers.set('Host', upstream_domain);

}
const content_type = new_response_headers.get('content-type');
if (content_type != null && content_type.includes('text/html') && content_type.includes('UTF-8')) {

}

}

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

![](https://pic.bbimax.com/wp-content/uploads/2021/01/2021012704.png)
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:
![](https://pic.bbimax.com/wp-content/uploads/2021/01/2021012705-1024x761.png)
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。
![](https://pic.bbimax.com/wp-content/uploads/2021/01/2021012707-1024x558.png)
进入你要添加域名的主域,点击“添加记录”
![](https://pic.bbimax.com/wp-content/uploads/2021/01/2021012708.png)
点击上方的workers,点击添加路由
![](https://pic.bbimax.com/wp-content/uploads/2021/01/2021012710-1024x601.png)
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:
![](https://pic.bbimax.com/wp-content/uploads/2021/01/2021012711.png)
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。
