从 on_message 获取公会 ID

Question

I'm currently trying to make a server prefix system using json.

I'm trying to get the prefix from the prefixes.json file but I get this:

This is the on_message I'm using

@bot.event
async def on_message(message):
    if '<@754643724193235035>' == message.content:
        channel = message.channel
        a = open('prefixes.json', 'r')
        serverprefix = json.load(a)
        await channel.send("My prefix is:")
        await channel.send(serverprefix['message.guild.id'])
    await bot.process_commands(message)

This is the json I'm using

{
    "712329859562315886": ";",
    "709202272655118233": "~"
}

There's also been another thing bugging me, how could I add serverprefix['message.guild.id'] to af""?

Answer 1

The reason of the error is you try to get a value from a key named message.guild.id . Obviously there is no key with that name. So you have to use string fromatting.

You should change await channel.send(serverprefix['message.guild.id']) to await channel.send(serverprefix[f'{message.guild.id}']) . So you can get the prefix from json file.
