怎样加速GitHub文件下载？
如果直连GitHub，最近怎么连图片都加载不出来了？下载速度20 kb/s ，玩蛇皮啊？怎样加速GitHub文件下载？Github Download Faster With Cloudflare Worker
遇到问题先Google,发现有修改hosts的方法,不过2020年,这个方法已经凉了吧？！没有测试
前端时间刷电报群,似乎有点印象，CDN加速下载，用CloudFlare的worker来实现。
首先，一个托管在CloudFlare上的域名，试用免费版本的Worker,建立一个xxx.xxx.work.dev的四级域名？
在script内粘贴以下内容：
Deploy然后打开网站即可。
Danger! 💀
每天上限10万次调用
addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request).catch((err) => { return new Response(err.message) }))
})
const html = `
<html><head><h1 style="font-size:32px;font-family:verdana;color:red;">Github直链加速下载每日10w次调用 </h1></head><body>
<input type="url" placeholder="url" id="url" style="border: 6px solid powderblue;color: blue; width: 60%; display: block;">
<input
type="submit" id="submit" value="submit"

<a id="a" href="""></a>
