discord.py添加到服务器上的json文件中添加

问题描述：

我希望我的机器人在对名为settings.json的JSON文件执行$ prefix（所需的前缀）时添加服务器ID和选择的前缀。我在下面有这个JSON文件的示例。

I am wanting my bot to add the server ID and prefix of choice when they do $prefix (desired prefix) to the JSON file called settings.json. I have an example of this JSON file below.

{
  "496019377515266060": "$"
}

我需要它，因此当用户键入$ prefix（所需前缀）时，它将添加其服务器ID和选择的前缀（如果不存在或不存在）将仅更新前缀。我可以做自定义前缀，但是我做不到，因此用户可以更改它们。

I need it so when users type $prefix (desired prefix) it will add their server ID and the prefix of choice if not there or if it is there it will just update the prefix. I have got as far as making custom prefixes but I cannot make it so users can change them.

注意
我不是使用重写分支。

NOTE I am not using the rewrite branch.

我正在假设您的代码或多或少像此答案。每当我们更改文件时，我们都可以使用标准库 json 模块编辑文件：

I'm operating under the assumption that your code looks more or less like this answer. We can use the standard library json module to edit the file whenever we change it:

from discord import commands
import json

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

def prefix(bot, message):
    id = message.server.id
    return prefixes.get(id, default_prefix)

bot = commands.Bot(command_prefix=prefix)

@bot.command(name="prefix", pass_context=True)
async def _prefix(ctx, new_prefix):
    # Do any validations you want to do
    prefixes[ctx.message.server.id] = new_prefix
    with open("prefixes.json", "w") as f:
        json.dump(prefixes, f)
