二：在群里运行

main.py

from mirai import Mirai, WebSocketAdapter, FriendMessage, GroupMessage, At

if __name__ == '__main__':
    bot = Mirai(
        qq=12345678, # 改成你的机器人的 QQ 号
        adapter=WebSocketAdapter(
            verify_key='yirimirai', host='localhost', port=8080
        )
    )

    @bot.on(FriendMessage)
    def on_friend_message(event: FriendMessage):
        if str(event.message_chain) == '你好':
            return bot.send(event, 'Hello, World!')

    @bot.on(GroupMessage)
    def on_group_message(event: GroupMessage):
        if At(bot.qq) in event.message_chain:
            return bot.send(event, [At(event.sender.id), '你在叫我吗？'])

    @bot.on(GroupMessage)
    def on_group_message_new(event: GroupMessage):
        """发挥你的创意……"""

    bot.run()
