添加多个前缀discord.py

Question

我想为每个服务器实现自定义前缀，以及一个永久前缀，这意味着人们可以使用默认前缀.和@bot，并且前缀存储在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}') 

我试着找到一种方法，并尝试了下面的方法，结果出现了错误。任何帮助都将不胜感激。

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

json文件格式：

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

这是的改进版本

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)
