添加多个前缀 discord.py

Question

我想为每个服务器实现自定义前缀，以及一个永久性前缀，即机器人提及，这意味着人们可以使用默认前缀 . 以及 @bot，前缀是存储在 json 文件中。

这是我当前的代码：

with open("prefixes.json") as f:
    prefixes = json.load(f)
default_prefix = "."

def get_prefix(client, message): 
    with open('prefixes.json', 'r') as f: 
        prefixes = json.load(f) 
    return prefixes[str(message.guild.id)] 

client = commands.Bot(
    command_prefix= (get_prefix),
    intents=intents
    )


@client.event
async def on_guild_join(guild): 
    with open('prefixes.json', 'r') as f: 
        prefixes = json.load(f) 

    prefixes[str(guild.id)] = '.'

    with open('prefixes.json', 'w') as f: 
        json.dump(prefixes, f, indent=4) 

@client.event
async def on_guild_remove(guild): 
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)

    prefixes.pop(str(guild.id)) 

    with open('prefixes.json', 'w') as f: 
        json.dump(prefixes, f, indent=4)

@client.command(pass_context=True)
@commands.has_permissions(administrator=True) 
async def prefix(ctx, prefix): 
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)

    prefixes[str(ctx.guild.id)] = prefix

    with open('prefixes.json', 'w') as f: 
        json.dump(prefixes, f, indent=4)

    await ctx.send(f'`Prefix changed to:` {prefix}')

我试图找到一种方法并尝试了下面的方法，但它抛出了错误。任何帮助将不胜感激。

client = commands.Bot(
    command_prefix= [(get_prefix), '<@!123>'],
    intents=intents
    )

json 文件格式：

{
    "121212121212121221": "-",
    "121212121212121222": "-",
    "121212121212121223": "!",
    "121212121212121224": "-",
    "121212121212121225": "."
}

这是一个改进版本[=11=]

def get_prefix(client, message):
    prefix = default_prefix 
    with open('prefixes.json', 'r') as f: 
        prefixes = json.load(f) 
        prefix = prefixes[str(message.guild.id)] 

    return commands.when_mentioned_or(prefix)(client, message)

client = commands.Bot(command_prefix=get_prefix, case_insensitive=True, intents=intents)
