分享下载 vscode 国内镜像的脚本

去 vscode 官网下载太慢了。写了个简单的函数，分享下

cmd_download()
{
    cdn='vscode.cdn.azure.cn'
    orig_url='https://code.visualstudio.com/sha/download?build=stable&os=linux-x64'
    cur_url=$(curl -ILs -o /dev/null -w '%{url_effective}\n' "$orig_url")
    echo "$cur_url"
    new_url=$(sed "s#https://.*/stable#https://$cdn/stable#g" <<< $cur_url)
    echo "$new_url"
    wget -c "$new_url"
}
