快速下载Snap软件

在云服务器上使用snap时, 遇到了这样的问题:

snap install的下载速度太慢。
snap没有镜像站。
https://uappexplorer.com/snaps已经不能用了。
运行环境不能够 (不敢) 使用代理。

参考Ask Ubuntu上的How to get snap download url:

通过snapcraft.io页面找到需要的snap包的名称, 以Redis Desktop Manager为例, 其PackageName是redis-desktop-manager。

使用一个HTTP Headers中带有Snap-Device-Series的GET请求api.snapcaft.io获取相应snap包的下载链接, 比如:

1
curl -H 'Snap-Device-Series: 16' http://api.snapcraft.io/v2/snaps/info/redis-desktop-manager

得到返回信息如下:
