Question

我最近一直在研究一个 Discord 机器人，我所有的命令都在一个 py 文件中。我目前正在尝试为我的机器人实现 cogs，因为我的计划是让它 24/7 并且公开运行，所以如果出现问题，我可以轻松修复它而无需关闭整个机器人（并使脚本本身更干净）和组织）。我对使用 JSON 和 cogs 比较陌生，因此非常感谢任何帮助。

注意 1：我不想传递绝对路径，因为我将在 VPS 上托管此机器人。
注意 2：我的 reports.json 文件在 \cogs 文件夹中，而不是在 \CogTest 文件夹中。

尝试运行它会引发此错误：

Traceback (most recent call last):
  File "C:\Users\User\Desktop\test\CogTest\cogs\warns.py", line 14, in <module>
    class Warns(commands.Cog):
  File "C:\Users\User\Desktop\test\CogTest\cogs\warns.py", line 20, in Warns
    with open('reports.json', encoding='utf-8') as f:
FileNotFoundError: [Errno 2] No such file or directory: 'reports.json'

这是我的警告类示例：

def setup(client):
    client.add_cog(Warns(client))

这是主要的加载/卸载代码，如果您愿意，可以检查它是否有任何问题

# Imports 

import discord
import random
import asyncio
import json
import datetime
import os
from discord import Permissions
from discord import Intents
from discord.ext import commands
from discord.ext.commands import has_permissions
from discord.ext.commands import MissingPermissions
from discord.ext.commands import BucketType
from os import listdir


client = commands.Bot(command_prefix = "y!")

# Load / Unload

@client.command()
async def load(ctx, extension):
    client.load_extension(f'cogs.{extension}')

@client.command()
async def unload(ctx, extension):
    client.unload_extension(f'cogs.{extension}')

for filename in os.listdir('./cogs'):
    if filename.endswith('.py'):
        client.load_extension(f'cogs.{filename[:-3]}')

client.run('token here')

discord.py 在 cogs 中使用 JSON？
