Python Discord bot检查用户是否为管理员

您好，我对使用discord编写python代码还不熟悉，我已经尝试过制作一个命令，告诉用户他们是否是管理员，但是。。。它一点也不起作用

    @client.command(name="whoami",description="who are you?")
async def whoami():
    if message.author == client.user:
        return
    if context.message.author.mention == discord.Permissions.administrator:
        msg = "You're an admin {0.author.mention}".format(message)  
        await client.send_message(message.channel, msg)
    else:
        msg = "You're an average joe {0.author.mention}".format(message)  
        await client.send_message(message.channel, msg)

当我试着输入whoami时，我得到了这个结果

Ignoring exception in command whoami
Traceback (most recent call last):
  File "/home/python/.local/lib/python3.6/site-packages/discord/ext/commands/core.py", line 50, in wrapped
    ret = yield from coro(*args, **kwargs)
  File "<stdin>", line 3, in whoami
NameError: name 'message' is not defined

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/python/.local/lib/python3.6/site-packages/discord/ext/commands/bot.py", line 846, in process_commands
    yield from command.invoke(ctx)
  File "/home/python/.local/lib/python3.6/site-packages/discord/ext/commands/core.py", line 374, in invoke
    yield from injected(*ctx.args, **ctx.kwargs)

忽略命令whoami中的异常

更改

@client.command(name="whoami",description="who are you?")
async def whoami():

到

然后，您可以使用

ctx

获取各种内容，比如编写它的用户、消息内容等等

要查看

用户是否是管理员，请执行

如果ctx.message.author.server\u权限。管理员：
如果用户是管理员，则应返回
True

您的代码应该如下所示：

import discord
import asyncio
from discord.ext.commands import Bot

client = Bot(description="My Cool Bot", command_prefix="!", pm_help = False, )
@client.event
async def on_ready():
  print("Bot is ready!")
  return await client.change_presence(game=discord.Game(name='My bot'))

@client.command(pass_context = True)
async def whoami(ctx):
    if ctx.message.author.server_permissions.administrator:
        msg = "You're an admin {0.author.mention}".format(ctx.message)  
        await client.send_message(ctx.message.channel, msg)
    else:
        msg = "You're an average joe {0.author.mention}".format(ctx.message)  
        await client.send_message(ctx.message.channel, msg)
client.run('Your_Bot_Token')

您可以使用查看用户是否具有该权限

然后，我们可以处理该检查失败将引发的错误，以便发送失败消息

from discord.ext.commands import Bot, has_permissions, CheckFailure

client = Bot()

@client.command(pass_context=True)
@has_permissions(administrator=True)
async def whoami(ctx):
    msg = "You're an admin {}".format(ctx.message.author.mention)  
    await client.send_message(ctx.message.channel, msg)

@whoami.error
async def whoami_error(error, ctx):
    if isinstance(error, CheckFailure):
        msg = "You're an average joe {}".format(ctx.message.author.mention)  
        await client.send_message(ctx.message.channel, msg)

如果
message.author.server\u permissions.administrator
不起作用

将其更改为
message.author.guild\u permissions.administrator

或者尝试
message.author.top\u role.permissions.administrator
，这将返回bool

一件事是，通常情况下，服务器所有者将管理员设置为服务器顶部角色，因此这在大多数情况下都有效。但是如果他们不这样做，第三个sol将不起作用。
什么不起作用？有例外吗？
消息
来自哪里？只是添加了我尝试激活命令时发出的信息。你是什么意思？抱歉，我是一个非常新的人，如果它明显地将上下文添加到您的第一个if语句
if context.message.author==client.user:
应该更新此答案：AttributeError:'Member'对象没有属性'server\u permissions'它的'guild\u permissions'
from discord.ext.commands import Bot, has_permissions, CheckFailure

client = Bot()

@client.command(pass_context=True)
@has_permissions(administrator=True)
async def whoami(ctx):
    msg = "You're an admin {}".format(ctx.message.author.mention)  
    await client.send_message(ctx.message.channel, msg)

@whoami.error
async def whoami_error(error, ctx):
    if isinstance(error, CheckFailure):
        msg = "You're an average joe {}".format(ctx.message.author.mention)  
        await client.send_message(ctx.message.channel, msg)
