Discord.py Bot的权限系统

2 years ago

Permissions是该类的名称 . 要获取消息作者权限，您应该访问作者的server_permissions属性 .

if ctx.message.author.server_permissions.administrator:
 # you could also use server_permissions.kick_members

更新：

验证调用命令的人员权限的更好方法是使用 commands 扩展名的check功能，特别是has_permissions检查 . 例如，如果您只想向拥有 manage_roles 权限或 ban_members 权限的人员打开命令，您可以像这样编写命令：

from discord import Member
from discord.ext.commands import has_permissions, MissingPermissions

@bot.command(name="kick", pass_context=True)
@has_permissions(manage_roles=True, ban_members=True)
async def _kick(ctx, member: Member):
    await bot.kick(member)

@_kick.error
async def kick_error(error, ctx):
    if isinstance(error, MissingPermissions):
        text = "Sorry {}, you do not have permissions to do that!".format(ctx.message.author)
        await bot.send_message(ctx.message.channel, text)

发现接受的答案的提示可能不起作用：

• discord.py库的重写版本和预重写版本可能存在兼容性问题，这些版本仍然是非过时的，不推荐使用且仍在使用中 .

• 机器人还应该检查它自己的权限，以排除错误的一个原因 .

• 如果有错误，或者机器人本身的权限无效，机器人应该说些什么，对吗？

• 需要实现某些东西以防止机器人尝试在DM或组上下文中使用此命令 . 它几乎总是错误的 .

我提出以下解决方案（假设您使用命令扩展名）：

import discord
from discord.ext import commands
import time
@bot.command(pass_context=True,description="Kicks the given member. Please ensure both the bot and the command invoker have the permission 'Kick Members' before running this command.")
async def kick(ctx, target:discord.Member):
    """(GUILD ONLY) Boot someone outta the server. See 's!kick' for more."""
    if not str(ctx.message.channel).startswith("Direct Message with "):
        msg=await bot.say("Checking perms...")
        time.sleep(0.5)
        if ctx.message.server.me.server_permissions.kick_members:
            if ctx.message.author.server_permissions.kick_members:
                await bot.edit_message(msg,new_content="All permissions valid, checking issues with target...")
                time.sleep(0.5)
                if target==ctx.message.server.owner:
                    await bot.edit_message(msg, new_content="All permissions are correct, but you're attempting to kick the server owner, whom you can't kick no matter how hard you try. Whoops!")
                else:
                    if target==ctx.message.server.me:
                        await bot.edit_message(msg, new_content="Whoops! All permissions are corrent, but you just tried to make me kick myself, which is not possible. Perhaps you meant someone else, not poor me?")
                    else:
                        await bot.edit_message(msg, new_content="All permissions correct, and no issues with target being self or server owner, attempting to kick.")
                        time.sleep(2)
                        try:
                            await bot.kick(target)
                            await bot.edit_message(msg, ":boom: BAM! ***kicc'd***")
                        except Exception:
                            await bot.edit_message(msg, new_content="I was unable to kick the passed member. The member may have a higher role than me, I may have crashed into a rate-limit, or an unknown error may have occured. In that case, try again.")
            else:
                await bot.edit_message(msg, new_content="I've the correct permissions, {}, but you do not. Perhaps ask for them?").format(ctx.message.author.mention)
        else:
            await bot.edit_message(msg, new_content="I'm just a poor bot with no permissions. Could you kindly grant me the permission `Kick Members`? Thanks! :slight_smile:")
    else:
        await bot.say("'Tis a DM! This command is for servers only... try this again in a server maybe? :slight_smile:")
