在镜像加速项目下许多人贡献了加速镜像,建议本项目能够将加速镜像的选择上做更灵活的处理
因为我发现ghp.ci的可靠性不好,很多情况下都下不动,下面的issue提供了许多筛选可用加速站点的方法,包括powershell实现的方案
例如
$GithubMirrors = @( # 注意,如果你的浏览器使用了代理,那么部分镜像站会和代理冲突,所以可能命令行中测试可以访问的链接在浏览器中确打不开镜像站,可以关闭代理或换个浏览器后重新验证该镜像站的可用性 #搜集到的链接可以用gpt进行修改,将链接包裹引号(指令:为这些链接分别添加引号);或者自己粘贴到文件文件中然后编写脚本转换为数组格式 'https://github.moeyy.xyz', #

或者考虑适配此项目:[Scoop: scoop国内镜像优化库,能够加速scoop安装及bucket源文件,无需用户设置代理。](https://gitee.com/scoop-installer/scoop)
用户可以选择分支,从而得到非加速得到原始github连接,用户借由gitee上的加速方案来加速
Sorry, something went wrong.
作为一个应用仓库可做的比较有限。 https://gitee.com/scoop-installer/scoop 是个不错的方案,可以考虑去提 issue 增加如下支持:
