discord.py如何给用户分配角色v1.0版

Question

import discord
import logging
from discord.utils import get
from discord.ext import commands
logging.basicConfig(level=logging.INFO)
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(pass_context=True)
async def setrole(ctx, a: str):
    member = ctx.message.author
    role = discord.utils.get(member.guild.roles, name=a)
    await member.add_roles(member, role)

这是我用来尝试为输入命令的人分配角色的代码。我的服务器中可用的角色是 rs6，所以代码应该是 !setrole rs6 但它不起作用。

Ignoring exception in command setrole:
Traceback (most recent call last):
  File "C:\Users\Ruiyang(Harry)Wang\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\ext\commands\core.py", line 83, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Workshop\example_bot.py", line 19, in setrole
    await member.add_roles(member, role)
  File "C:\Users\Ruiyang(Harry)Wang\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\member.py", line 641, in add_roles
    await req(guild_id, user_id, role.id, reason=reason)
  File "C:\Users\Ruiyang(Harry)Wang\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\http.py", line 223, in request
    raise NotFound(r, data)
discord.errors.NotFound: 404 Not Found (error code: 10011): Unknown Role

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

Traceback (most recent call last):
  File "C:\Users\Ruiyang(Harry)Wang\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\ext\commands\bot.py", line 892, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\Ruiyang(Harry)Wang\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\ext\commands\core.py", line 797, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\Ruiyang(Harry)Wang\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\ext\commands\core.py", line 92, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: NotFound: 404 Not Found (error code: 10011): Unknown Role

我试着在行 role = discord.utils.get(member.guild.roles, name=a) 之后做 print(role) 它打印了正确的 rs6。有人请帮助我！谢谢！

您可以使用命令装饰器做一些时髦的事情。与将 arg 的类型设置为 str 的方式相同，您也可以将其设置为不和谐对象：

@bot.command() # Note that context is automatically passed in rewrite
async def setrole(ctx, role: discord.Role):
    await ctx.author.add_roles(role)
    await ctx.send(f"I gave you {role.mention}!")

如果找不到角色，您可能需要一个错误处理程序来处理：

@setrole.error
async def _role_error(ctx, error):
    if isinstance(error, commands.errors.BadArgument):
        await ctx.send("I couldn't find that role!")
