Discord.py 如何使命令適用於某些角色？

Question

我有這段代碼，如果有人具有“服務器開發人員”角色，則假設運行該命令，該命令將賦予某人“監獄”角色以用於該命令的阻止量，但它不起作用並且沒有給出錯誤。

import discord
from discord.ext import commands
import ctx
import re
import time
from time import sleep
import asyncio

PREFIX = "$"
bot = commands.Bot(command_prefix=PREFIX, description="Hi")

@commands.has_role("Server Developer")
@bot.command()
async def court(ctx, user_mentioned: discord.Member, time: int):
    user_id = message.mentions[0].id
    user = message.mentions[0]
    role = discord.utils.get(message.guild.roles, name="Jail")
    await user_mentioned.add_roles(role)
    await ctx.send(
        f"sending <@{user_id}> to court!"
    )
    await asyncio.sleep(time)
    await user_mentioned.remove_roles(role)

bot.run(TOKNE_GOES_HERE)

Answer 1

您忘記在命令頂部添加@bot.command() 。 在@commands.has_role("Server Developer")和async def court(ctx, user_mentioned: discord.Member, time: int):

像這樣做：

import discord
from discord.ext import commands
import ctx
import re
import time
from time import sleep
import asyncio

PREFIX = "$"
bot = commands.Bot(command_prefix=PREFIX, description="Hi")

@commands.has_role("Server Developer")
@bot.command()
async def court(ctx, user_mentioned: discord.Member, time: int):
    user_id = ctx.message.mentions[0].id
    user = ctx.message.mentions[0]
    role = discord.utils.get(ctx.message.guild.roles, name="Jail")
    await user_mentioned.add_roles(role)
    await ctx.send(
        f"sending <@{user_id}> to court!"
    )
    await asyncio.sleep(time)
    await user_mentioned.remove_roles(role)

bot.run(TOKNE_GOES_HERE)

Answer 2

使用任何檢查裝飾器，如has_role或is_owner ，不會使 function 成為命令，因此您仍然必須添加@commands.command()或@bot.command() ：

@bot.command()
@commands.has_role("Server Developer")
async def court(ctx, user_mentioned: discord.Member, time: int):
    user_id = message.mentions[0].id
    user = message.mentions[0]
    role = discord.utils.get(message.guild.roles, name="Jail")
    await user_mentioned.add_roles(role)
    await ctx.send(
        f"sending <@{user_id}> to court!"
    )
    await asyncio.sleep(time)
    await user_mentioned.remove_roles(role)

bot.run(TOKNE_GOES_HERE)

Answer 3

您可以嘗試在命令中添加檢查，如下所示：

if not discord.utils.get(ctx.guild.roles, name="Server Developer") in ctx.user.roles:
    return
else:
    # do something
