我想检查执行命令的用户是否具有管理员角色
这是我的代码:
@client.command(pass_context=True)
@commands.has_role(name='Admin')
async def unban(self, ctx, user):
"""
unbans a user name
:user: user name not mentioned
"""
try:
ban_list = await client.get_bans(ctx.message.server)
if not ban_list:
await self.client.send_message(ctx.message.channel, 'Ban list is empty')
return
for bans in ban_list:
if user.lower() in str(bans).lower():
try:
await self.client.unban(ctx.message.server, bans)
await self.client.send_message(ctx.message.channel, 'Unbanned')
except discord.Forbidden:
await client.send_message(ctx.message.channel, "I don't have permissions to unban")
return
except discord.HTTPException:
await client.send_message(ctx.message.channel, 'Unban failed')
return
else:
await client.send_message(ctx.message.channel, 'This user is not banned from this server')
except:
await client.send_message(ctx.message.channel, "You don't have ``Admin`` role")
但是当我尝试在没有 Admin
角色的情况下执行该命令时,它会显示此错误:
Ignoring exception in command unban
Traceback (most recent call last):
File "C:\Users\danyb\Anaconda3\lib\site-packages\discord\ext\commands\bot.py", line 846, in process_commands

discord.ext.commands.errors.CheckFailure: The check functions for command unban failed.
如何检查用户的角色列表中是否具有管理员角色,然后他可以执行此命令?
最佳答案
使用装饰器 @commands.has_role(name='Admin')
已经可以保护该方法免受非管理员用户的攻击。</p>
它在调用方法时引发异常,而不是在方法内部引发异常。
