因为 #391 这个问题,续签失败的通知只发送到面板,但我最近两个星期没有登录面板,导致我没有及时收到通知,结果签发证书被限流了,对 Let's Encrypt 的服务器也造成了一点点微不足道但可以避免的压力。

希望可以支持将续签结果通知发送到 Telegram bot 或其他如邮箱等强通知的渠道。

自己不会从头写,只会看着改,所以只能提供一段参考代码,期待实现。

发送 Telegram 通知 Shell 脚本

## 发送 Telegram 通知,$1:消息内容
notify_telegram () {
    local message="$(echo -e $1 | sed 's!&!%26!g')"
    ## local tg_api_url="https://api.telegram.org/bot${TG_BOT_TOKEN}/sendMessage"
    local send_result err_code err_message
    local cmd_proxy_user cmd_proxy

## 使用 Telegram API 反代地址替代原始 API 地址
    if [ -z "$TG_API_HOST" ]; then
        local tg_api_url="https://api.telegram.org/bot${TG_BOT_TOKEN}/sendMessage"
    else
        if [[ "${TG_API_HOST: -1}" != "/" ]]; then
            TG_API_HOST="${TG_API_HOST}/"
        fi
        if [[ "http://" == "${TG_API_HOST:0:7}" || "https://" == "${TG_API_HOST:0:8}" ]]; then
            local tg_api_url="${TG_API_HOST}bot${TG_BOT_TOKEN}/sendMessage"
        else
            local tg_api_url="https://${TG_API_HOST}bot${TG_BOT_TOKEN}/sendMessage"
        fi
    fi

    [[ $TG_PROXY_USER ]] && cmd_proxy_user="--proxy-user ${TG_PROXY_USER}" || cmd_proxy_user=""
    [[ $TG_PROXY_ADDRESS ]] && cmd_proxy="--proxy $TG_PROXY_ADDRESS $cmd_proxy_user" || cmd_proxy=""

    send_result=$(curl -Ssk $cmd_proxy -H "Content-Type:application/x-www-form-urlencoded" -X POST -d "chat_id=${TG_USER_ID}&text=${message}&disable_web_page_preview=true" "$tg_api_url")
    send_result=$(echo "$send_result" | sed '{:label; N; s/\n/\\n/g; b label; s/\\n$//}')
    err_code=$(echo "$send_result" | jq .ok)
    if [[ $err_code == true ]]; then
        echo -e "(N) $(date +'%Y-%m-%dT%H:%M:%S') - [$(basename $0)] 发送Telegram通知成功\n"
    else
        err_code=$(echo "$send_result" | jq .err_code)
        [[ err_code == 400 ]] && err_message="请主动给bot发送一条消息并检查接收用户ID是否正确。"
        [[ err_code == 401 ]] && err_message="Telegram Bot Token 填写错误。"
        echo -e "(W) $(date +'%Y-%m-%dT%H:%M:%S') - [$(basename $0)] 发送Telegram通知失败,错误代码:$err_code,错误消息:$err_message\n"
    fi
}
