我不确定您要命令执行什么操作，但这是如何将json实现到discord.py中的示例.

I'm not sure what you want your command to do, but here's an example of how you would implement json into discord.py.

在这里，无论何时执行命令，机器人都会打开一个json文件，读取数据，并查看消息作者是否在数据中.如果作者在数据中，则将键/值对删除，并将数据重写到json文件中:

Here, whenever the command is executed, the bot opens a json file, reads the data, and sees if the message author is in the data. If the author is in the data, the key/value pair is deleted, and the data is rewritten into the json file:

import json

@bot.command()
async def afkremoveme(ctx):

    f = "yourFile.json"
    author = str(ctx.author.id)

    with open(f, "r") as read_file:
        data = json.load(read_file)

    if author in data: # if any key in the dictionary is an integer, it is converted to a string when a json file is written

        del data[author]
        newData = json.dumps(data, indent=4)

        with open(f, "w") as write_file:
            write_file.write(newData)

        await ctx.send(f"{ctx.author.display_name} is no longer afk...")

这正在读取一个看起来像这样的json文件(用您的ID替换000000):

This is reading a json file that looks like this (replace 000000 with your id):

{
    "000000" : "afk",
    "someOtherGuy" : "afk"
}

所有这些都使用字典和json模块.如果您不熟悉这两个概念，这里有一些链接可以帮助您:-)

All of this uses dictionaries and the json module. If you're unfamiliar with either of the concepts, here are a few links to help you out :-)

Python字典， Python-Json
