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

问题描述

我正在使用discord.py和asyncio制作discord机器人。该机器人具有 kick 和 ban 之类的命令，这些命令显然不适合普通用户使用。

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.

我想创建一个简单的系统，该系统使用 ctx.message.author 来检测用户角色具有的权限

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.

我不希望机器人程序检测到特定的角色名称，因为这些名称在服务器之间会有所不同。我也不想让机器人拥有多个文件来保持它的简单性。

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.

我已经看到了discord.py文档和其他各种资源，但都没有包含如何进行操作的示例。实现它们讨论的各种方法。

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.

例如，这是我的机器人发出的单个命令：

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)
    else:
        permission_error = str('Sorry ' + ctx.message.author + ' you do not have permissions to do that!')
        await BSL.send_message(ctx.message.channel, permission_error)

的地方声明是我自己做的尝试。 ＃ctx.message.author.Permissions.administrator 被注释掉，因为它不起作用，并替换为 True 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.

谢谢您的任何帮助和建议。

Thank you for any help and suggestions in advance.

推荐答案

权限 是类的名称。要获得消息作者的权限，您应该访问 server_permissions 作者的财产。

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

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

更新：

验证用户调用命令权限的更好方法是使用命令扩展名的commands / commands.html＃checks rel = noreferrer>检查功能，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，您可以这样编写命令：

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)

@_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)
