Discord bot 检查用户是否为管理员

问题描述

您好，我是不和谐的 python 编码新手，我试图创建一个命令来告诉用户他们是否是管理员，但是很好......它一点也不工作

Hi i'm new to python coding with discord and I have tried to make a command that tells the user if they are a admin or not but well... its not working in the slightest

    @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)

然后当我尝试输入 whoami 时得到这个

I then get this when I try to type whoami

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

解决方案

改变

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

到

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

然后你可以使用ctx来获取各种东西，比如写它的用户，消息内容等等

Then you can use ctx to get all kinds of stuff like the user that wrote it, the message contents and so on

要查看 User 是否是管理员，请执行以下操作
if ctx.message.author.server_permissions.administrator: 如果用户是管理员，则应该返回 True

To see if a User is an administrator do
if ctx.message.author.server_permissions.administrator: which should return True if the user is an an Administator

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')
