message 类包含有关消息的 author，您可以使用它来确定是否回复消息.作者 是 会员 对象(或其超类 User 如果频道是私有的)，它具有 id 属性，但也支持用户之间的直接逻辑比较.

The message class contains information on the message's author, which you can utilize to determine whether or not to respond to the message. author is a Member object (or its superclass User if the channel is private), which has an id property but also supports direct logical comparisons between users.

例如:

@bot.event
async def on_message(message):
    if message.author != bot.user:
        await bot.send_message(message.channel, message.content)

应该按需要发挥作用
