使用不带 cogs 的 discord.py 是否可以实现 OOP?

问题描述

最近几天，我一直在尝试将用 discord.py 编写的不和谐机器人的结构调整为更面向 OOP 的结构(因为周围有功能并不理想).

These last few days, I've been trying to adapt the structure of a discord bot written in discord.py to a more OOP one (because having functions lying around isn't ideal).

但我发现的问题比我想象的要多得多.问题是我想将所有命令封装到一个单个类中，但我不知道要使用哪些装饰器以及我必须继承哪些类以及如何继承.

But I have found way more problems that I could have ever expected. The thing is that I want to encapsulate all my commands into a single class, but I don't know what decorators to use and how and which classes I must inherit.

到目前为止，我所取得的成果是类似于下面的代码片段.它会运行，但在执行命令时会抛出类似

What I've achieved so far is code like the snippet down below. It runs, but at the moment of executing a command it throws errors like

discord.ext.commands.errors.CommandNotFound:命令状态"没找到

discord.ext.commands.errors.CommandNotFound: Command "status" is not found

我使用的是 Python 3.6.

I'm using Python 3.6.

from discord.ext import commands


class MyBot(commands.Bot):

    def __init__(self, command_prefix, self_bot):
        commands.Bot.__init__(self, command_prefix=command_prefix, self_bot=self_bot)
        self.message1 = "[INFO]: Bot now online"
        self.message2 = "Bot still online {}"

    async def on_ready(self):
        print(self.message1)

    @commands.command(name="status", pass_context=True)
    async def status(self, ctx):
        print(ctx)
        await ctx.channel.send(self.message2 + ctx.author)


bot = MyBot(command_prefix="!", self_bot=False)
bot.run("token")

解决方案

要注册命令你应该使用self.add_command(setup)，但是你不能有self<setup 方法中的/code> 参数，因此您可以执行以下操作:

To register the command you should use self.add_command(setup), but you can't have the self argument in the setup method, so you could do something like this:

from discord.ext import commands
    
class MyBot(commands.Bot):
    
    def __init__(self, command_prefix, self_bot):
        commands.Bot.__init__(self, command_prefix=command_prefix, self_bot=self_bot)
        self.message1 = "[INFO]: Bot now online"
        self.message2 = "Bot still online"
        self.add_commands()
    
    async def on_ready(self):
        print(self.message1)
    
    def add_commands(self):
        @self.command(name="status", pass_context=True)
        async def status(ctx):
            print(ctx)
            await ctx.channel.send(self.message2, ctx.author.name)
        
        self.add_command(status)
    
bot = MyBot(command_prefix="!", self_bot=False)
bot.run("token")
