Question

我正在尝试使用discord.py为不和谐的服务器对机器人进行编程。我想创建一个命令，允许用户为自己分配名称颜色（即红色或蓝色），我试图通过创建角色来实现此目的。但是我在使用最新形式的discord.py分配角色时遇到了一些麻烦。

@client.command()
async def role(ctx, * role: discord.Role):
  user = ctx.message.author
  await user.add_roles(role)

有人知道如何解决我遇到的错误。错误如下：

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'tuple' object has no attribute 'id'

在我看来，问题在于'*'...

如果您使用代码并添加打印行以查看实际传递给您的方法的内容，您将看到以下结果：

代码

@client.command()
async def role(ctx, * role: discord.Role):
  print(role)
  user = ctx.message.author
  await user.add_roles(role)

输出

(<Role id=671750373761089546 name='Red'>,)
Ignoring exception in command role:
Traceback (most recent call last):
  File "/home/dual/PyProjects/Discord/Chandler/env/lib/python3.7/site-packages/discord/ext/commands/core.py", line 79, in wrapped
    ret = await coro(*args, **kwargs)
  File "main.py", line 57, in role
    await user.add_roles(role)
  File "/home/dual/PyProjects/Discord/Chandler/env/lib/python3.7/site-packages/discord/member.py", line 616, in add_roles
    await req(guild_id, user_id, role.id, reason=reason)
AttributeError: 'tuple' object has no attribute 'id'

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

Traceback (most recent call last):
  File "/home/dual/PyProjects/Discord/Chandler/env/lib/python3.7/site-packages/discord/ext/commands/bot.py", line 863, in invoke
    await ctx.command.invoke(ctx)
  File "/home/dual/PyProjects/Discord/Chandler/env/lib/python3.7/site-packages/discord/ext/commands/core.py", line 728, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "/home/dual/PyProjects/Discord/Chandler/env/lib/python3.7/site-packages/discord/ext/commands/core.py", line 88, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'tuple' object has no attribute 'id'

如果您删除“ *”并保持其他所有内容不变，则外观如下：

代码

@client.command()
async def role(ctx, role: discord.Role):
  print(role)
  user = ctx.message.author
  await user.add_roles(role)

输出

Red

没有'*'的角色将添加到调用命令的用户。仅当角色拼写正确且区分大小写时，此方法才有效。我建议您实施某种输入验证。
