Discord.py Bot 的权限系统 [英] Permission System for Discord.py Bot

本文介绍了Discord.py Bot 的权限系统的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!


我正在使用 discord.py 和 asyncio 制作一个不和谐机器人.该机器人具有像 kickban 这样的命令,显然普通用户不应该使用这些命令.

I am in the process of making a discord bot using discord.py and asyncio. The bot has commands like kick and ban which obviously should not be available to normal users.

我想制作一个简单的系统,该系统将使用 ctx.message.author 检测用户角色的权限,以获取发送命令的用户.

I want to make a simple system which will detect what permissions the user's role has using ctx.message.author to get the user who sent the command.


I do not want the bot to detect a specific role name as these vary across servers. I also prefer not to have multiple files for the bot to keep it simple.

我看过 discord.py 文档和其他各种来源,但没有一个包含如何实现他们谈论的各种方法的示例.

I have seen the discord.py documentation and various other sources but none contain examples of how to implement the various methods they talk about.


As an example, here is a single command from my bot:

async def kick(ctx, userName: discord.User):
    if True: #ctx.message.author.Permissions.administrator
        await BSL.kick(userName)
        permission_error = str('Sorry ' + ctx.message.author + ' you do not have permissions to do that!')
        await BSL.send_message(ctx.message.channel, permission_error)

if else 语句是我自己尝试做的.#ctx.message.author.Permissions.administrator 被注释掉,因为它不起作用并替换为 True 用于测试目的.

Where the if else statement is my attempt of doing this on my own. The #ctx.message.author.Permissions.administrator is commented out as it does not work and replaced with True for testing purposes.


Thank you for any help and suggestions in advance.


Permissions 是类的名称.要获得消息作者权限,您应该访问 guild_permissions 作者的属性.

Permissions is the name of the class. To get the message authors permissions, you should access the guild_permissions property of the author.

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


验证调用命令的人的权限的更好方法是使用 commands 扩展的 ="nofollow noreferrer">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 权限的人打开命令,则可以这样编写命令:

A better way to validate the permissions of the person invoking the commands is by using the check feature of the commands extension, specifically the has_permissions check. For example, if you wanted to open your command only to people who had either the manage_roles permission or the ban_members permission, you could write your command like this:

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)

async def kick_error(ctx, error):
    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)
