Question

我正在尝试创建一个命令，其中显示来自 json 的随机模因。不幸的是我不能这样做......我可以正常使用 random.choice 来完成，但由于我是一个懒惰的人来更新代码，所以我总是创建一个命令，允许我将它们添加到 json 中。所以我必须能够随机提取我的json的主键。我该怎么办？

代码：

@client.command(aliases=["Meme","MEME"])
async def meme(ctx):
    await ctx.message.delete()
    meme_data_dict = meme_data.json
    url = random.choice(list(meme_data_dict.keys))
    print(url)
    author = meme_data_dict[url]["autore"]
    title = meme_data_dict[url]["titolo"]
    channel = client.get_channel(638016878589116416)
    if ctx.channel.id == channel.id:
        embed = discord.Embed(
            title=f'{title}',
            color=0x003399
        )
        embed.set_author(name=f'fatto da {author}')
        embed.set_footer(text=f'Richiesto da {ctx.author.name}')
        embed.set_image(url=url)
        await ctx.send(embed=embed)
    else:
        embed = discord.Embed(
            color=0xa61022
        )
        embed.set_author(
            name=f"Per questo comando devi usare {channel.name}!",
        )
        await ctx.send(embed=embed, delete_after=10.0)
        return

Json（你的名字是 meme_data.json）：

{"https://cdn.discordapp.com/avatars/491769129318088714/f23fd300d377ab133db1d6ac7db5d10b.webp?size=1024": {"autore": "10", "titolo": "sesso pazzoide"}, "https://cdn.discordapp.com/attachments/638016878589116416/839977460384923659/soviet_soldier_2.jpg": {"autore": "pene", "titolo": "ciaociao"}}

这是我的 json 的活动方式：

@client.event
async def on_ready():
    global meme_data
    try:
        with open('meme_data.json') as f:
            meme_data = json.load(f)
    except FileNotFoundError:
        print("Impossibile caricare meme_data.json")
        meme_data = {}

错误：

Ignoring exception in command meme:
Traceback (most recent call last):
  File "C:\Users\PC GIUSEPPE\PycharmProjects\LMIIBot Development\venv\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:/Users/PC GIUSEPPE/PycharmProjects/LMIIBot Development/LMIIBot Development.py", line 2235, in meme
    meme_data_dict = meme_data.json
AttributeError: 'dict' object has no attribute 'json'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\PC GIUSEPPE\PycharmProjects\LMIIBot Development\venv\lib\site-packages\discord\ext\commands\bot.py", line 903, in invoke

    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\PC GIUSEPPE\PycharmProjects\LMIIBot Development\venv\lib\site-packages\discord\ext\commands\core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc

要获取字典的随机对象（导入的 json 文件），请使用 url = random.choice(list(meme_data_dict.keys))。在您的代码中将是：

@client.command(aliases=["Meme","MEME"])
async def meme(ctx):
    await ctx.message.delete()
    meme_data_dict = meme_data #you have to rename your variable meme, for example to meme_data, because there is already the function called meme
    url = random.choice(list(meme_data_dict.keys()))
    print(url)
    author = meme_data_dict[url]["autore"]
    title = meme_data_dict[url]["titolo"]
    #the rest of your code can stay the same

如果这不能回答您的问题，请进一步说明问题所在。
