Question

所以我有这段代码可以给用户on_message提供1个exp，但是当我调用$stream时，应该给出50 exp的命令却得到了错误.OperationalError: database is locked 。当用户调用漫游器前缀bot = commands.Bot(command_prefix = '$', case_insensitive=True)时，如何为用户设置例外？

向用户提供+1 exp的代码，如果该表不存在，则创建表

@commands.Cog.listener()
async def on_message(self,message):
    db = sqlite3.connect('banco.sqlite')
    cursor = db.cursor()
    cursor.execute(f'SELECT user_id FROM levels WHERE guild_id = {message.author.guild.id} AND user_id = {message.author.id}')
    result = cursor.fetchone()
    if result is None:
        sql = (f'INSERT INTO levels(guild_id, user_id, exp, lvl) VALUES(?,?,?,?)')
        val = (message.guild.id, message.author.id, 0, 0)
        cursor.execute(sql, val)
        db.commit()
    else:
        cursor.execute(f'SELECT user_id, exp, lvl FROM levels WHERE guild_id = {message.author.guild.id} AND user_id = {message.author.id}')
        result1 = cursor.fetchone()
        exp = int(result1[1])
        sql = ('UPDATE levels SET exp = ? WHERE guild_id = ? and user_id = ?')
        val = (exp + 1, str(message.guild.id), str(message.author.id))
        cursor.execute(sql, val)
        db.commit()
        cursor.close()
        db.close()

工作命令

@commands.command()
async def stream(self,ctx):
    db = sqlite3.connect('banco.sqlite')
    cursor = db.cursor()
    cursor.execute(f'SELECT user_id FROM levels WHERE guild_id = {ctx.author.guild.id} AND user_id = {ctx.author.id}')

    em = discord.Embed(title = '', color = (0x70c886))
    em.add_field(name = 'Donates da stream :',value = (f'lucrou +<:bbc:639345897922101248> 50 ') )
    await ctx.send(embed = em)

    cursor.execute(f'SELECT user_id, exp, lvl FROM levels WHERE guild_id = {ctx.author.guild.id} AND user_id = {ctx.author.id}')
    result1 = cursor.fetchone()
    exp = int(result1[1])
    sql = ('UPDATE levels SET exp = ? WHERE guild_id = ? and user_id = ?')
    val = (exp + 50, str(ctx.guild.id), str(ctx.author.id))
    cursor.execute(sql, val)
    db.commit()
    cursor.close()
    db.close()

错误

文件 “ /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/discord/client.py”， _run_event中的第312行等待coro（* args，** kwargs）文件“ /Users/CIP/Documents/GitHub/economia/cogs/dinheiro.py”，第56行， on_message db.commit（）sqlite3.OperationalError：数据库已锁定

如何为on_message事件Discord.py设置例外？
