Bot未响应Telegram中的频道帖子Bot API(python-Telegram-Bot)

我正在开发一个电报机器人,使用python电报机器人来处理和回复特定渠道中的帖子。机器人成功启动并显示“机器人正在运行…”,但它从不回复频道中的帖子。

以下是处理频道帖子的相关代码:

async def handle_channel_post(self, update: Update, context: ContextTypes.DEFAULT_TYPE):
        """Handle new channel posts by adding the message link as a reply."""
        try:
            # Get the message and channel info
            message = update.channel_post or update.message
            if not message:
                return
                
            # Verify this is from our target channel
            if message.chat.username != self.channel_username:
                return
            
            channel_id = message.chat.id
            message_id = message.message_id
            
            # Construct the message link
            if str(channel_id).startswith("-100"):
                # Private channels (or supergroups)
                link = f"https://t.me/c/{str(channel_id)[4:]}/{message_id}"
            else:
                # Public channels
                link = f"https://t.me/{self.channel_username.replace('@', '')}/{message_id}"
            
            # Create the reply text
            reply_text = f"View message: [Click here]({link})"
            
            # Reply to the channel post
            await context.bot.send_message(
                chat_id=channel_id,
                text=reply_text,
                reply_to_message_id=message_id,
                parse_mode="Markdown"
            )
            
        except Exception as e:
            print(f"Error handling channel post: {e}")

主要方法如下:

async def main():
    BOT_TOKEN = "<MT_BOT_TOKEN>"
    CHANNEL_USERNAME = "@TestTGBot123"
    
    bot = ChannelBot(BOT_TOKEN, CHANNEL_USERNAME)

    await bot.start()

我尝试了另一个频道和不同的频道类型,但仍然不起作用。该机器人是管理员,也有在频道中发布的权限。
