尝试指定成员时出现位置错误

Question

您好，我正在尝试获取会员姓名而不是作者姓名

我尝试了一些方法，例如 for member is message.server.members:，它返回了服务器中每个成员的多个结果，并尝试了 member: discord.Member 作为产生错误的签名：

这是我正在使用的：

async def on_message_delete(self, message):
    server = message.server
    author = message.author
    role =  get(server.roles, name="Powerbot")
    channel = get(message.server.channels, name="mod-log")
    time = datetime.utcnow()
    cleanmsg = message.content
    for i in message.mentions:
        cleanmsg = cleanmsg.replace(i.mention, str(i))
    fmt = '%H:%M:%S'
    name = author
    name = " ~ ".join((name.name, name.nick)) if name.nick else name.name
    if role not in author.roles:
        infomessage = "A message by {}, was deleted in {} by {}".format(message.author.mention, message.channel.mention, member,mention)
        delmessage = discord.Embed(description=infomessage, colour=discord.Color.purple(), timestamp=time)
        delmessage.add_field(name="Message:", value=cleanmsg)
        delmessage.set_footer(text="User ID: {}".format(message.author.id))
        delmessage.set_author(name=name + " message deleted.", icon_url=message.author.avatar_url)
        delmessage.set_thumbnail(url="http://i.imgur.com/fJpAFgN.png")
        try:
            await self.bot.send_message(channel, embed=delmessage)
        except:
            pass

member.mention 所在的行。

infomessage = "A message by {}, was deleted in {} by {}".format(message.author.mention, message.channel.mention, member.mention)

示例输出：作者的消息在频道中被会员删除。

如果有人可以提供帮助，将不胜感激。

Answer 1

我很确定客户不会被告知谁删除了该消息，只是知道它已被删除。 message 对象本身不包含该信息，而来自 rewrite 分支的 RawMessageDeleteEvent 也没有。

我对底层的 Discord API 不是很熟悉，但 Message Delete 网关事件看起来是 discord.py 在删除消息时收到的，它没有提及删除者的身份。

无法从您使用的 discord 版本中查看删除消息的人，因为稳定的 discord.py 不包含对审计日志的支持。 您将需要 discord.py 重写才能使用以下解决方案：

@bot.event()
async def on_message_delete(msg):
    audits = await msg.guild.audit_logs(limit=10, action=discord.AuditLogAction.message_delete)
    async for audit in audits:
        try:
            await audit.target.get_message(msg.id)
        except discord.NotFound:
            continue      
        print(audit.user)
        break

这是假设消息即使在被删除后仍会保留。如果上述方法不起作用，我想我们能做的最好的就是：

@bot.event()
async def on_message_delete(msg):
    audits = await msg.guild.audit_logs(limit=10, action=discord.AuditLogAction.message_delete)
    audit = await audits.get(extra__channel=msg.channel)
    print(audit.user)
