推荐答案
由于这个问题与python-telegram-bot有关，以下信息与之相关:
As this question is related to python-telegram-bot, information below is related to it:
当您向机器人的调度程序添加处理程序时，您可以指定各种预先构建的过滤器(在 docs, github) 或者您可以创建自定义过滤器以过滤传入的更新.
When you add handlers to your bot's dispatcher, you can specify various pre-built filters (read more at docs, github) or you can create custom ones in order to filter incoming updates.
要限制对特定用户的访问，您需要在初始化处理程序时添加Filters.user(username="@telegramusername")，例如:
To limit access to a specific user, you need to add Filters.user(username="@telegramusername") when initializing handler, e.g.:
dispatcher.add_handler(CommandHandler("start", text_callback, Filters.user(username="@username")))
此处理程序仅接受来自用户名为 @username 的用户的 /start 命令.
This handler will accept /start command only from user with username @username.
您还可以指定用户 ID 而不是用户名，我强烈建议您这样做，因为后者是非常数的，并且可以随着时间的推移而更改.
You can also specify user-id instead of username, which I would highly recommend, as latter is non-constant and can be changed over time.
