discord bot autorole -- 在 _run_event 中来自 getattr(self, event)(*args, **kwargs)

Question

我是 Python 新手，我的 Discord Bot 有一些问题，我没有得到解决。机器人应该自动为首次加入服务器的用户分配角色。我可以成功设置autorole。但是当用户加入服务器时，控制台会出现如下错误信息。

Ignoring exception in on_member_join

Answer 1

在您的cmd_autorole.py 文件中，get() 函数是异步的，但在您的主文件中您还没有等待它。 你必须写role = await cmd_autorole.get(member.server) 而不是role = cmd_autorole.get(member.server)。

不要在第二个事件中使用@client.event，而是尝试使用@client.listen，如下所示：

@client.listen
async def on_message(message):
    if message.content.startswith(STATICS.PREFIX):
        invoke = message.content[len(STATICS.PREFIX):].split(" ")[0]
        args = message.content.split(" ")[1:]
        if commands.__contains__(invoke):
            await commands.get(invoke).ex(args, message, client, invoke)
        else:
            await client.send_message(message.channel, embed=discord.Embed(color=discord.Color.red(), description=("The command `%s` is not valid!" % invoke)))


@client.listen
async def on_member_join(member):
    # await client.send_message(member, "**Hello %s,**\n\nwelcome on Discord-Server __**%s**__!\nPlease look first at the main channel %s .\n\nHave Fun!" % (member.name, member.server.name, discord.utils.get(member.server.channels, id="532425431526277135").mention))
    role = cmd_autorole.get(member.server)
    if not role is None:
        await client.add_role(member, role)
