如何只允许管理员执行命令
问题描述
我正在编写以下命令
@bot.command(pass_context=True)
async def admins_only_command(ctx, *, args):
'''do stuff
我怎样才能将此命令限制为仅限管理员?我尝试查看 ctx.author.roles.role 并显示 @everyone.如何检查给定用户是否为 admin?
how can i restrict this command to admins only? I tried looking at ctx.author.roles.role and it says @everyone. How can i check if the given user is an admin or not?
解决方案
有两种方法:通过角色白名单使用 has_any_role
There are two ways: by a whitelist of roles using has_any_role
@bot.command(pass_context=True)
@commands.has_any_role("Big Cheese", "Medium Cheese")
async def admins_only_command(ctx, *, args):
'''do stuff'''
或通过使用 <代码>has_permissions
@bot.command(pass_context=True)
@commands.has_permissions(administrator=True)
async def admins_only_command(ctx, *, args):
'''do stuff'''
这两个装饰器都是 Checks，并且会引发 CommandError 的一些子类，如果它们失败，您可以选择处理.
Both of these decorators are Checks, and will raise some subclass of CommandError for you to optionally handle if they fail.
