python电报bot过滤器url

问题描述

很抱歉寻求帮助，但我找不到有关我需要做什么的信息。

我从 Python 开始并创建了我的第一个 Telegram 机器人。我希望机器人过滤器文本仅查找 URL，并在找到时触发。

例如，如果有人在聊天中输入“www.google.com”，我希望机器人将其识别为 URL，然后执行 X 操作。我尝试过滤单词以获取准确的 URL，但我做错了。

我正在尝试使用 Filters.entity(URL)，但无法编写完整的必要代码。

这是实际的机器人代码：

import logging
from telegram.ext import Updater,CommandHandler,ConversationHandler,MessageHandler,Filters
import os
import random
import requests

TOKEN = "XXXXX"
PORT = int(os.environ.get('PORT','8443'))
updater = Updater(TOKEN)

# 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 update and
# context. Error handlers also receive the raised TelegramError object in error.
def start(update,context):
   """Send a message when the command /start is issued."""
   update.message.reply_text('Hi!')

def coin(update,context):
   ''' ⚪️/⚫️ Moneda 
   Genera un número elatorio entre 1 y 2.
   '''
   cid=update.message.chat_id
   msg="⚫️ Cara" if random.randint(1,2)==1 else "⚪️ Cruz"
   # Responde directametne en el canal donde se le ha hablado.
   update.message.reply_text(msg)

def help(update,context):
   """Send a message when the command /help is issued."""
   update.message.reply_text('Help!')

def links(update,context):
   """Echo the user message."""
   url = str(update.message.text)
   if url.lower() == '*morning*':
   update.message.reply_text(update.message.text)
   
def error(update,context):
   """Log Errors caused by Updates."""
   logger.warning('Update "%s" caused error "%s"',update,context.error)

def main():
   """Start the bot."""
   # Create the Updater and pass it your bot's token.
   # Make sure to set use_context=True to use the new context based callbacks
   # Post version 12 this will no longer be necessary
   updater = Updater(TOKEN,use_context=True)

   # 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("help",help))
   dp.add_handler(CommandHandler("coin",coin))          

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

   # log all errors
   dp.add_error_handler(error)

   # Start the Bot
   updater.start_webhook(listen="0.0.0.0",port=PORT,url_path=TOKEN,webhook_url="XXXXX/" + TOKEN)

   # 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()
