一键加速你的 GitHub 下载：告别龟速，拥抱飞速！

还在为 GitHub 下载速度慢而烦恼吗？还在对着进度条望眼欲穿吗？今天，就为大家带来一款神器——gh-proxy，让你彻底告别 GitHub 下载龟速时代，体验飞一般的速度！

项目地址：https://github.com/hunshcn/gh-proxy

简介

github release、archive以及项目文件的加速项目，支持clone，有Cloudflare Workers无服务器版本以及Python版本

如何部署 gh-proxy？

Cloudflare Workers部署（推荐）

首页：https://workers.cloudflare.com

1.注册，登陆，Start building。
2.复制 index.js 到左侧代码框，Save and deploy。如果正常，右侧应显示首页。

先部署默认的Workers，然后再点击编辑代码

复制index.js到左侧代码框并部署

右侧显示主页

ASSET_URL是静态资源的url（实际上就是现在显示出来的那个输入框单页面）
PREFIX是前缀，默认（根路径情况为"/"），如果自定义路由为example.com/gh/*，请将PREFIX改为 '/gh/'，注意，少一个杠都会错！
3.为 Workers 项目使用优选域名
