用于对话的 Python Telegram Bot 按钮入口点

Question

我正在使用 Python Telegram Bot 编写一个简单的机器人来处理一些对话。

我尝试改进文档页面中的内联键盘示例代码，以便在单击特定 InlineKeyboardButton 时开始对话。

这是我的代码：

    #!/usr/bin/env python
# pylint: disable=C0116,W0613
# This program is dedicated to the public domain under the CC0 license.

"""
First, a few callback 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:
Example of a bot-user conversation using ConversationHandler.
Send /start to initiate the conversation.
Press Ctrl-C on the command line or send a signal to the process to stop the
bot.

我想知道是否能够点击“选项 1”按钮启动特定的对话渠道，并点击“选项 2”按钮启动另一个对话渠道。

我在互联网上找到了一些参考来修改顶部的代码，但我无法让它工作。

有类似情况的人吗？

谢谢

Answer 1

CallbackQueryHandler(some_callback) 将处理任何传入的CallbackQuery。您应该使用CallbackQueryHandler 的pattern 参数。另见this example。

编辑：因为您有两个CallbackQueryHandler(some_callback)（一个在对话内部，一个在对话外部），所以最多其中一个可以触发更新。请记住Dispatcher.add_handler 的“顺序和优先级计数”逻辑。
