Telegram 机器人每日定时任务“设置宵禁时间段”

将客服机器人加入到群聊中后，可以让机器人定时禁言群里面的所有普通成员，一段时间后重新恢复发言，这样能很好的管理成员提出的问题，避免在非正常时间段内提问。

这里用到了 TG 的两个机器人：

• @BotFather 创建机器人（API_TOKEN）
• @getidsbot 输出你的用户ID（chat_id）或者群ID（group_id）

配置脚本

创建目录并将脚本放进去

mkdir -p /opt/tg_bot
cp nightmute_bot.py /opt/tg_bot/
chmod +x /opt/tg_bot/nightmute_bot.py

cat nightmute_bot.py

import logging
import datetime
from telegram import ChatPermissions, Update
from telegram.ext import (
    ApplicationBuilder, CommandHandler, ContextTypes
)
from backports.zoneinfo import ZoneInfo

BOT_TOKEN = "Your_API_TOKEN"
GROUP_ID = -100xxx


logging.basicConfig(level=logging.INFO)

async def mute_group(context: ContextTypes.DEFAULT_TYPE):
    await context.bot.set_chat_permissions(
        chat_id=GROUP_ID,
        permissions=ChatPermissions(can_send_messages=False)
    )
    await context.bot.send_message(
        chat_id=GROUP_ID,
        text="🌙 夜间模式已开启！\n\n我要睡到明早七点，今天又收获了不少呢，祝好梦 😴"
    )
    logging.info("夜间模式已开启")

async def unmute_group(context: ContextTypes.DEFAULT_TYPE):
    await context.bot.set_chat_permissions(
        chat_id=GROUP_ID,
        permissions=ChatPermissions(can_send_messages=True)
    )
    await context.bot.send_message(
        chat_id=GROUP_ID,
        text="☀ 夜间模式结束啦！\n\n今天又是元气满满的一天，加油 😉"
    )
    logging.info("夜间模式结束")


async def start(update: Update, context: ContextTypes.DEFAULT_TYPE):
    await update.message.reply_text("Bot 已启动")

async def post_init(app):
    tz = ZoneInfo("Asia/Shanghai")
    app.job_queue.run_daily(mute_group, time=datetime.time(hour=22, minute=0, tzinfo=tz))
    app.job_queue.run_daily(unmute_group, time=datetime.time(hour=7, minute=0, tzinfo=tz))
    logging.info("定时任务已设置")

def main():
    app = ApplicationBuilder().token(BOT_TOKEN).post_init(post_init).build()

    app.add_handler(CommandHandler("start", start))
    app.add_handler(CommandHandler("mute", mute_group))
    app.add_handler(CommandHandler("unmute", unmute_group))

    logging.info("Bot 正在运行...")
    app.run_polling()  # <== 这是阻塞式同步调用，不需要 asyncio.run

if __name__ == "__main__":
    main()

配置脚本运行环境

创建 Python 虚拟环境

apt install -y python3 python3-pip python3-venv
cd /opt/tg_bot
python3 -m venv venv
source venv/bin/activate
pip install python-telegram-bot==20.7
pip install python-telegram-bot[job-queue]
deactivate
