如果Python腳本異常，如何從Telegram機器人發送消息？

Question

我正在使用wetherstation，它每分鍾都會收集溫度和濕度。 在這個項目中，我想添加一個Telegram機器人，如果數據記錄停止，它會向我發送一條消息。
我下載了Telegram機器人庫，並使用我的Telegram機器人進行了一些測試。
目前，我的機器人可以通過向我的機器人發送/humidity來回答是否需要當前濕度。

#!/usr/bin/env python

#
# Simple Bot to reply to Telegram messages
# This program is dedicated to the public domain under the CC0 license.

"""
This Bot uses the Updater class to handle the bot.

First, a few handler functions are defined. Then, those functions are passed to
the Dispatcher and registered at their respective places.
Then, the bot is started and runs until we press Ctrl-C on the command line.

Usage:
Basic Echobot example, repeats messages.
Press Ctrl-C on the command line or send a signal to the process to stop the
bot.

from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
import logging
import read_from_database


# Enable logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
                    level=logging.INFO)

logger = logging.getLogger(__name__)


# Define a few command handlers. These usually take the two arguments bot and
# update. Error handlers also receive the raised TelegramError object in error.
def start(bot, update):
    update.message.reply_text('Hi!')

def status(bot, update):
    zeitstempel = read_from_database.get_timestamp()
    update.message.reply_text('letzter Eintrag: {:%d.%m.%Y %H:%M}'.format(zeitste$

def temperatur(bot, update):
    temperatur = read_from_database.get_temperature()
#    update.message.reply_text('letzter Temperatureintrag: %s ' % temperatur + u'$
    update.message.reply_text('letzter Temperatureintrag: %s C' % temperatur)

def feuchtigkeit(bot, update):
    feuchtigkeit = read_from_database.get_humidity()
    update.message.reply_text('letzter Feuchtigkeitseintrag: %s %%' % feuchtigkei$

def echo(bot, update):
    update.message.reply_text(update.message.text)


def error(bot, update, error):
    logger.warn('Update "%s" caused error "%s"' % (update, error))

def main():
    # Create the EventHandler and pass it your bot's token.
    updater = Updater("TOKEN")

    # Get the dispatcher to register handlers
    dp = updater.dispatcher

    # on different commands - answer in Telegram
    dp.add_handler(CommandHandler("start", start))
    dp.add_handler(CommandHandler("status", status))
    dp.add_handler(CommandHandler("feuchtigkeit", feuchtigkeit))
    dp.add_handler(CommandHandler("temperatur", temperatur))

    # on noncommand i.e message - echo the message on Telegram
    #dp.add_handler(MessageHandler(Filters.text, echo))

    # log all errors
    dp.add_error_handler(error)

    # Start the Bot
    updater.start_polling()

    # Run the bot until you press Ctrl-C or the process receives SIGINT,
    # SIGTERM or SIGABRT. This should be used most of the time, since
    # start_polling() is non-blocking and will stop the bot gracefully.
    updater.idle()


if __name__ == '__main__':
    main()

但是我不知道當我的python腳本在記錄期間遇到異常時如何發出alarm 。 是否可以從python腳本發送消息而不向我的Telegram機器人發送請求？

Answer 1

使用updater.bot.send_message發送消息
