问题描述

我试图让我的机器人通过吐出您没有权限{}来告诉用户是否有错误但是当我尝试使用此代码时:


I'm trying to make my bot tell a user if there is a error by spitting out You do not have the permissions {} But when I try to use this code:
@client.command(pass_context = True)
async def ban(ctx, member : discord.Member, *, content: str):
    if ctx.message.author == client.user:
        return
    if ctx.message.author.server_permissions.administrator:
        msg = (str(member) + "has been banned for" + str(content)).format(ctx.message)
        await client.send_message(member, content)
        await client.ban(member)
        await client.send_message(ctx.message.channel, msg)
@ban.error
async def ban_error(error, ctx):
    if isinstance(error, CheckFailure):
        msg = "Sorry but you do not have the permissions {}".format(ctx.message.author.mention)  
        await client.send_message(ctx.message.channel, msg)

discord bot dms 用户，python 控制台中没有错误，如果我删除 @ban.error 片段，我会得到一个权限错误太低.
The discord bot dms the user and there is no errors in the python console and if I remove the @ban.error piece I get a too low of a permission error.
推荐答案

CheckFailure 只有在检查失败.您的代码中没有检查，所以这永远不会发生.您可以使用 if 语句转换为检查.commands.has_permissions" rel="nofollow noreferrer">commands.has_permission:

CheckFailure only gets raised if a check fails. There are no checks in your code, so this never happens. You can convert your if statement to a check very easily using commands.has_permission:

@client.command(pass_context = True)
@has_permissions(administrator=True)
async def ban(ctx, member : discord.Member, *, content: str):
    msg = "{} has been banned for {}".format(ctx.message.author.mention, content)
    await client.send_message(member, content)
    await client.ban(member)
    await client.send_message(ctx.message.channel, msg)

错误处理程序可能会隐藏有价值的错误信息.我们可以只调用内置错误处理的机器人来处理任何其他不是 CheckFailures

It may be the case that the error handler is suppressing valuable error information. We can just call the bots built in error handling for any other errors that are not CheckFailures

from discord.ext.commands import CheckFailure
from discord import Forbidden


@ban.error
async def ban_error(error, ctx):
    if isinstance(error, CheckFailure):
        msg = "Sorry but you do not have the permissions {}".format(ctx.message.author.mention)  
        await client.send_message(ctx.message.channel, msg)
    elif isinstance(error, Forbidden):
        await client.send_message(ctx.message.channel, "I do not have the correct permissions")
    else:
        print(error)
        await client.on_command_error(error, ctx)
