一、域名托管到cloudflare
登录cloudflare->添加站点->填写域名(例如阿里云)->继续选择free套餐->继续->保存cloudflare分配的DNS地址->进入阿里云域名管理->进入DNS管理/DNS修改把DNS地址修改为cloudflare分配的两个DNS->保存->回到cloudflare->网站中域名打上对号表示托管成功(修改DNS成功后cloudflare会发邮件一般几分钟就配置成功了)->进入网站/SSL/TLS开启始终使用HTTPS就可以免费使用SSL
二、加速访问GitHub
登录cloudflare->Workers 和 Pages->创建->创建 Worker->保存->进入刚创建的Worker->编辑代码worker.js修改为以下代码->保存部署->进入刚刚的Worker->设置/触发器中添加自定义域名因为cloudflare自动分配的域名访问慢->通过自定义域名就可以畅快的访问GitHub了
// 你要镜像的网站.
const upstream = 'github.com'// 镜像网站的目录，比如你想镜像某个网站的二级目录则填写二级目录的目录名，镜像 google 用不到，默认即可.
const upstream_path = '/'// 镜像站是否有手机访问专用网址，没有则填一样的.
const upstream_mobile = 'github.com'// 屏蔽国家和地区.
const blocked_region = ['KP', 'SY', 'PK', 'CU']// 屏蔽 IP 地址.
const blocked_ip_address = ['0.0.0.0', '127.0.0.1']// 镜像站是否开启 HTTPS.
const https = true// 文本替换.
const replace_dict = {'$upstream': '$custom_domain', '//github.com': ''}// 以下保持默认，不要动
