使用国内的云服务器时，对于Github是极其不友好的，经常无法连接上，raw.githubusercontent.com域名也是已经凉凉，git clone能连上的时候也是龟速。

所幸，发现了这一款工具，用过之后感觉浑身舒爽。

如果你以前没有使用过Cloudflare Workers，可以参考这篇文章的详细步骤：https://www.nbmao.com/archives/4324

这里就不多赘述了

Demo

https://git.haoduck.cf 建议是自己搭建一个，自己搭建比较稳定，Cloudflare Workers免费套餐的每天10万请求数是绰绰有余的。如果只是偶尔用用，直接用这个也无妨。

使用方法

1.

加速下载文件

打开https://git.haoduck.cf，然后输入要加速的链接(release文件等)

或者直接在链接前面加上https://git.haoduck.cf/ 示例： 从https://raw.githubusercontent.com/username/xxxxx/xxxxx变成https://git.haoduck.cf/raw.githubusercontent.com/username/xxxxx/xxxxx

2. 加速clone

将git clone https://github.com/username/xxx.git换成git clone https://git.haoduck.cf/github.com/username/xxx.git
