白嫖cloudflare搭建属于自己的git加速站

不想自己动手的话，文末也有搭建好的，可以直接去白嫖！

基于开源项目gh-proxy地址：https://github.com/hunshcn/gh-proxy

cloudflare地址：https://dash.cloudflare.com

首先访问cloudflare注册一个你自己的账户

然后点击workers

白嫖cloudflare搭建属于自己的git加速站-2022年8月1日更新

之后弹出来这个界面，你需要在输入框中输入你自己的workers的名字

请注意！一定要方便记忆，不要乱输，这个会出现在你的网址中！！！

输入好后点set up

然后选择订阅模式，白嫖怪直接free！

免费版本每天的访问次数是10w次，应该是远远够用的！

然后要验证邮箱！

去你邮箱完成验证

验证完成后刷新，点击创建

然后按下图填写，之后点创建

然后点击快速编辑

将下面的代码复制 --->点击查看源码<--
