discord.py 级别系统 JSONDecodeError

Question

Here is a photo of json file. 我想在discord.py中做关卡系统，这是我的代码：

import discord
from discord.ext import commands
from discord.utils import get
import asyncio
import json

TOKEN = 'xxxx'
bot = commands.Bot(command_prefix='!')


@bot.event
async def on_message(message):
    with open(r'C:\\Users\\asus\\lvl.json', 'r') as f:
        users = json.load(f)
        user = discord.User

    async def update_data(users, user: discord.User):
        if not user in users:
            users[user] = {}
            users[user]['exp'] = 0
            users[user]['lvl'] = 1

    async def add_exp(users, user: discord.User, exp: float):
        users[user][exp] = exp + exp

    async def add_lvl(users, user: discord.User):
        exp = users[user]['exp']
        lvl = users[user]['lvl']
        if exp > lvl:
            await message.channel.send(f'{message.author.mention} достиг {str(lvl)} уровня!')
            lvl = lvl + 1
            exp = 0

    await update_data(users, str(message.author.id))
    await add_exp(users, str(message.author.id), float(0.1))
    await add_lvl(users, str(message.author.id))
    users[user]['exp'] = 0
    users[user]['lvl'] = lvl + 1

    with open('C:\\Users\\asus\\lvl.json', 'w') as f:
        json.dump(users, f)

    await bot.process_commands(message)

# RUN
bot.run(TOKEN)

但是我有这个错误，我认为它在 json 文件中存在一些问题，因为他将 '0,1' 复制为 str。请不要介意，请检查此错误并heeeeelp我请）：

请帮忙）

Answer 1

您的文件 C:\\Users\\asus\\lvl.json 不是有效的 JSON 格式。如果您在此处发送文件可能会有所帮助，但您需要将其转换为有效的 JSON 格式才能使用json.loads()。

Answer 2

JSON 文件如果不放一些东西就什么也做不了。清空文件，然后在上面写上{}。到时候应该修好了。
