Question

嗨，我是不和谐的python编码的新手，我试图制作一个命令来告诉用户他们是否是管理员，但是很好……它丝毫没有作用

    @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)

然后我尝试输入whoami时得到了

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)
  File "/home/python/.local/lib/python3.6/site-packages/discord/ext/commands/core.py", line 54, in wrapped
    raise CommandInvokeError(e) from e
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: NameError: name 'message' is not defined

Answer 1

如果message.author.server_permissions.administrator不起作用。

将其更改为message.author.guild_permissions.administrator

或者尝试message.author.top_role.permissions.administrator，这将给您带来麻烦。

有一件事是，通常服务器所有者将管理员设置为服务器的最高角色，因此这在大多数情况下都会起作用。但是，如果他们不这样做，那么第三个sol将无法工作。

更改

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

到

@client.command(pass_context=True)
async def whoami(ctx):

然后，您可以使用ctx获取各种内容，例如编写它的用户，消息内容等

要查看User是否为管理员
if ctx.message.author.server_permissions.administrator:，如果用户是管理员，则应返回True

您的代码应如下所示：

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has_permissions check来查看用户是否具有administrator特权。

然后我们可以处理未能通过检查以发送失败消息的错误。

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)

Discord bot检查用户是否为管理员
