好吧，下面的代码为 /start 命令添加了一个命令处理程序:

Well, the following code adds a command handler for the /start command:

dp = updater.dispatcher
dp.add_handler(CommandHandler('start', start))

我想添加一个处理程序，它可以在一个处理程序中处理 /download_video、/download_music 等命令.

I want to add a handler which would handle commands like /download_video, /download_music and so on all in one handler.

我想到的是:

dp.add_handler(CommandHandler(r'^download', download))

但它没有按预期工作！相反，当我发送 /^download

But it doesn't work as supposed! Instead it will work when I send a non-command string of /^download

我该怎么做?

推荐答案

迟到的答案.一种简单的方法是解析所有文本消息并检查它们是否以匹配的单词开头，即:

Late answer. A simple way is to parse all text messages and check if they start with the matching word, i.e.:

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

def parse_msg(update, context):
    if re.search("^(/test|/something_else)$", update.message.text, re.IGNORECASE | re.DOTALL):
       update.message.reply_text("send your content")

def main():
    updater = Updater("your_token", use_context=True)
    dp = updater.dispatcher
    dp.add_handler(MessageHandler(Filters.text, parse_msg)) # parses all text messages
    updater.start_polling()
    updater.idle()

if __name__ == '__main__':
    main()

通过发送以 /test 或 /something_else 开头的消息进行测试如果您打算在频道中使用它，请确保机器人有权读取消息:@Botfater >/setprivacy ->@bot_name ->禁用

---

Test by sending a message starting by /test or /something_else If you plan to use this in a channel, make sure the bot has permission to read messages: @Botfater > /setprivacy -> @bot_name -> Disable
