如何向 Discord py 角色限制命令添加拒绝消息

Question

我有这个代码：

import discord
from discord.ext import commands, tasks
import random
from itertools import cycle
from discord.utils import get
import os

bot = commands.Bot(command_prefix='-')


TOKEN = ''


@bot.event
async def on_ready():
    print('Logged in as')
    print(bot.user.name)
    print(bot.user.id)
    print('------')



@bot.command()
@commands.has_role('Admin')
async def test(ctx):
    await ctx.send(":smiley: :wave: Hello, there! :heart: ")

bot.run(TOKEN)

如何设置拒绝信息？我的意思是如果有人使用该命令但他没有管理员角色，机器人会说类似的话 "You aren't admin buddy!"

我已经试过了，但没有用

@bot.command()
@commands.has_role('Admin')
async def test(ctx):
    await ctx.send(":smiley: :wave: Hello, there! :heart: ")
    else:
        await ctx.send("You can't use this!")

Answer 1

当用户调用测试命令但他们没有 'Admin' 角色时，将抛出 commands.MissingRole 错误。你可以用 error handling.

捕捉到这个

import discord
from discord.ext import commands, tasks
import random
from itertools import cycle
from discord.utils import get
import os

TOKEN = ''

bot = commands.Bot(command_prefix='-')

@bot.event
async def on_ready():
    print('Logged in as')
    print(bot.user.name)
    print(bot.user.id)
    print('------')

@bot.command()
@commands.has_role('Admin')
async def test(ctx):
    await ctx.send(":smiley: :wave: Hello, there! :heart: ")

@test.error
async def test_error(ctx, error):
    if isinstance(error, commands.MissingRole):
        await ctx.send('''You aren't admin buddy!''')

bot.run('TOKEN')

Answer 2

这会让您在用户没有角色时向他们发送消息。您也可以拥有多个角色而不是管理员。

@bot.command()
async def test(ctx):
    if "Admin" in ctx.author.roles:
        await ctx.send(":smiley: :wave: Hello, there! :heart: ")
    else:
        await ctx.send("You are not an admin!")
