(python) Telegram bot-如何定期发送消息?

(python) Telegram bot- how to send messages periodically?

我对我的电报机器人感到进退两难。假设我必须创建一个函数,它会询问每个连接到机器人的用户,每个 week/month 一次,一个问题:

def check_the_week(bot, update):
reply_keyboard = [['YES', 'NO']]
bot.send_message(
    chat_id=update.message.chat_id,
    text=report,

    reply_markup=ReplyKeyboardMarkup(reply_keyboard, one_time_keyboard=True))  # sends the total nr of hours
update.reply_text("Did you report all you working hour on freshdesk for this week?",
                  ReplyKeyboardMarkup(reply_keyboard, one_time_keyboard=True))

if update.message.text == "YES":
    update.message.reply_text(text="Are you sure?",
                              reply_markup=ReplyKeyboardMarkup(reply_keyboard, one_time_keyboard=True))

    # Asks confirmation
    if update.message.text == "YES":
        update.message.reply_text(text="Thank you for reporting your working hours in time!")

    elif update.message.text == "NO":
        update.message.reply_text(text="Please, check you time reports and add missing")

elif update.message.text == "NO":
    update.message.reply_text(text="Please, check you time reports and add missing")

我希望每周触发此功能。我正在考虑使用 JobQueue。问题是,在这种情况下,函数应该有两个参数——bot AND job_queue,但没有更新:

def callback_30(bot, job):
    bot.send_message(chat_id='@examplechannel',
    text='A single message with 30s delay')

j.run_once(callback_30, 30)

我如何在电报机器人中创建一个作业计划程序(或任何其他解决方案)以每周触发一次我的功能? p.s。请不要 "while True"+time.sleep() 解决方案。循环永远卡住了,我试过了。

尝试使用cron。您只需要将新的聊天 ID 存储在某个地方(文件、数据库等)并从您的脚本中读取它。 例如每天晚上 9 点 (21:00) 运行 send_messages.py:

0 21 * * * python send_messages.py

在函数中定义作业时需要使用上下文参数。看这个例子:

   from telegram.ext import Updater, CommandHandler, MessageHandler,    Filters, InlineQueryHandler


def sayhi(bot, job):
    job.context.message.reply_text("hi")

def time(bot, update,job_queue):
    job = job_queue.run_repeating(sayhi, 5, context=update)

def main():
    updater = Updater("BOT TOKEN")
    dp = updater.dispatcher
    dp.add_handler(MessageHandler(Filters.text , time,pass_job_queue=True))


    updater.start_polling()
    updater.idle()

if __name__ == '__main__':
    main()

现在,在您需要的回调函数中 update. 输入 job.context

要定期发送消息,您可以使用JobQueue Extention from python-telegram-bot

举个例子

from telegram.ext import Updater, CommandHandler

def callback_alarm(bot, job):
    bot.send_message(chat_id=job.context, text='Alarm')

def callback_timer(bot, update, job_queue):
    bot.send_message(chat_id=update.message.chat_id,
                      text='Starting!')
    job_queue.run_repeating(callback_alarm, 5, context=update.message.chat_id)

def stop_timer(bot, update, job_queue):
    bot.send_message(chat_id=update.message.chat_id,
                      text='Stoped!')
    job_queue.stop()

updater = Updater("YOUR_TOKEN")
updater.dispatcher.add_handler(CommandHandler('start', callback_timer, pass_job_queue=True))
updater.dispatcher.add_handler(CommandHandler('stop', stop_timer, pass_job_queue=True))

updater.start_polling()

/start 命令将启动 JobQueue 并以 5 秒的间隔发送消息,队列可以通过 /stop 命令停止。
