作为开发者，经常使用借助GitHub进行开发，但是最近防火墙发力导致本就半死不活的GitHub在河北彻底无法访问github.com站点，所以以下几个办法供参考【ps:不考虑科学上网】

1.修改hosts
打开 http://tool.chinaz.com/dns?type=1&host=www.github.com&ip=
选择一个TTL最小的ip,比如我这里是新加坡的ip
之后打开这个路径C:WindowsSystem32driversetc找到hosts,将它复制一份到桌面

通过你的文本编辑器打开这个文件,并输入一行记录13.229.188.59 github.com,同理，如果需要 assets-cdn.github.com[CSS,JS加载慢，添加这个],avatars0.githubusercontent.com[用户头像不能访问，或者访问慢],avatars1.githubusercontent.com[用户头像不能访问，或者访问慢]，使用上面的方法找到dns域名，填入即可。
这种方法并不是一劳永逸的，因为nds时刻在变，所以一旦不能访问，还是先找可访问的dns域名吧。

2.Cloudflare Workers 反代
利用Cloudflare Workers搭建一个GitHub镜像供自己使用
在 cloudflare 上创建一个 worker
将下面所有内容拷贝，覆盖粘贴到 worker 里面，保存

之后通过worker 的子域名来访问GitHub
但是这种方法我是不大推荐的,因为这样不可以登录,也就是说不可以下载,如果想要下载则需要再新建一个worker然后输入以下代码

1. addEventListener('fetch', event => {
2.     event.respondWith(handleRequest(event.request).catch((err) => { return new Response(err.message) }))
