如何在 discord.py 中识别用户

Question

您好，我正在使用 on_member_update(before, after) 事件参考来查看我的 discord 服务器 go 的管理员和版主何时在线和离线监控管理员活动。 到目前为止，我可以让我的程序告诉我有人上线和下线以及何时上线，但我无法确定哪个用户上线和下线，所以我得到了这样的信息：

User: has come online at {current_time}.
User: has come online at {current_time}.
User: has come online at {current_time}.
User: has gone offline at {current_time}.
User: has gone offline at {current_time}.
User: has come online at {current_time}.
User: has gone offline at {current_time}.
User: has gone offline at {current_time}.

所以我不知道谁上线和下线，所以就我所知，它一遍又一遍是同一个人。 由于 on_member_update() 事件引用中没有成员参数，我如何识别成员/用户。 如果您需要任何澄清，请询问。 谢谢！

这是我的代码：

@client.event
async def on_member_update(before, after):
    current_time = datetime.datetime.now()
    if str(after.status) == 'offline':
        print(f'User: has gone offline at {current_time}.'.format(after.name, after.status))
    if str(after.status) == 'online':
        print(f'User: has come online at {current_time}.'.format(after.name, after.status))

Answer 1

after已经是 object 的成员，如果您想获取名称，只需添加.name ：

if str(after.status) == 'offline':
    print(f'{after.name}: has gone offline at {current_time}.'.format(after.name, after.status))
if str(after.status) == 'online':
    print(f'{after.name}: has come online at {current_time}.'.format(after.name, after.status)) 

# Output: JohnSmith: has gone offline at some_time.
# Output: JohnSmith: has gone online at some_time.

如果您也想获得 # 编号，您可以使用以下命令：

if str(after.status) == 'offline':
    print(f'{after.name}#{after.discriminator}: has gone offline at {current_time}.'.format(after.name, after.status))
if str(after.status) == 'online':
    print(f'{after.name}#{after.discriminator}: has come online at {current_time}.'.format(after.name, after.status)) 

# Output: JohnSmith#1234: has gone offline at some_time.
# Output: JohnSmith#1234: has gone online at some_time.

• before (User) – 更新用户的旧信息。

• after (User) – 更新用户的更新信息。
