我正在尝试检查作者是否在x服务器上具有x角色,以便能够使用该命令,但无法使其正常运行。我只能检查Author在该服务器中是否具有x角色。
这个想法:如果用户在x服务器中具有x角色,将能够在任何服务器上使用特殊命令。
role_id = 569712344226201600
author = ctx.message.author
if role_id in [role.id for role in author.roles]:
await ctx.send("message")
答案 0 :(得分:0)
内置的检查has_role
在这里不起作用,因为它仅检查调用命令的上下文的角色。编写检查来检查特定服务器中的角色的检查很容易上下文:
from discord.utils import get
from discord.ext.commands import check, MissingRole, CommandError
class GuildNotFound(CommandError):
def __init__(self, guild):
self.missing_guild = guild
message = f"I could not resolve guild: {guild}"
super().__init__(message)
class IsNotMember(CommandError):
def __init__(self, user, guild):
self.user = user
self.guild = guild
message = f"{user} is not a member of guild {guild}"
super().__init__(message)
def has_role_elsewhere(guild, role):
def predicate(ctx):
# Resolve the guild
if isinstance(guild, int):
resolved_guild = get(ctx.bot.guilds, id=guild)
else:
resolved_guild = get(ctx.bot.guilds, name=guild)
if resolved_guild is None:
raise GuildNotFound(guild)
# Resolve the member
member = resolved_guild.get_member(ctx.author.id)
if member is None:
raise IsNotMember(ctx.author, resolved_guild)
# Check for the role
if isinstance(role, int):
resolved_role = get(member.roles, id=role)
else:
resolved_role = get(member.roles, name=role)
if resolved_role is None:
raise MissingRole(role)
return True
return check(predicate)
这是很多代码,但是在我们实际的机器人程序中,我们只需要这样做:
@bot.command()
@has_role_elsewhere(guild=123456, role=569712344226201600)
async def mycommand(ctx):
...

您只需获取角色对象即可。
role = discord.utils.get(ctx.guild.roles, id=role_id_here)
然后:
if role in ctx.author.roles:
...
您的漫游器必须在这些服务器上。
