Discord py 让机器人在提到时做出回应，但带有单独的公会集前缀

Question

所以我设置了前缀，这样每个公会都可以通过命令单独更改它。我希望能够提及机器人并且它以“我的前缀是：”响应，但也响应使用设置前缀调用的命令。目前如果我添加 when

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

def Mentioned_prefix(client, message):
    prefix = get_prefix(client.message)
    return commands.when_mentioned_or(f'{prefix}')

client = commands.Bot(command_prefix = Mentioned_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.command()
@commands.has_permissions(administrator=True)
async def setprefix(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 is now: {prefix}')

@client.event
async def on_message(message):
    if client.user.mentioned_in(message):
        prefix = get_prefix(client, message)
        await message.channel.send(f"Prefix is:' {prefix} '")

您应该创建一个单独的函数来获取公会的前缀。您可以检查公会的 ID 是否在您的 'prefixes.json' 文件中，然后 return 这个。可以在下面的代码中找到进一步的解释。

def prefix_check(guild):
    # Check if this is a dm instead of a server
    # Will give an error if this is not added (if guild is None)
    if guild == None:
        return "!"
    try:
        # Check if the guild id is in your 'prefixes.json'
        with open('prefixes.json', 'r') as f:
            prefixes = json.load(f)
            p = prefixes[str(guild.id)]
    except:
        # Otherwise, default to a set prefix
        p = "!"
    # If you're confident that the guild id will always be in your json,
    # feel free to remove this try-except block

    return p

# on_message event
@client.event
async def on_message(message):
    if client.user.mentioned_in(message):
        # This is how you call the prefix_check function. It takes a guild object
        await message.channel.send(f"My prefix is {prefix_check(message.guild)}")
    
    # Don't forget to process, otherwise your commands won't work!
    await client.process_commands(message)

# In a command (using ctx), do use prefix_check(ctx.guild) to get the guild's prefix
