AIOHTTP meme 命令 discord.py

Question

我正在制作一个不和谐的机器人，我正在尝试制作一个随机的 meme 命令，这是我的错误和代码：

@client.command(pass_context=True)
async def meme(ctx):
    embed = discord.Embed(title="meme", description="test")

    async with aiohttp.ClientSession() as cs:
        async with cs.get('https://www.reddit.com/r/dankmemes/new.json?sort=hot') as r:
            res = await r.json()
            embed.set_image(res['data']['children'] [random.randint(0, 25)]['data']['url'])
            await client.say(embed=embed)

Ignoring exception in command meme
Traceback (most recent call last):
  File "C:\Users\atill\AppData\Local\Programs\Python\Python36\lib\site-packages\discord\ext\commands\core.py", line 50, in wrapped
    ret = yield from coro(*args, **kwargs)
  File "C:\Users\atill\Downloads\Epic Bot\server.py", line 165, in meme
    embed.set_image(res['data']['children'] [random.randint(0, 25)]['data']['url'])
TypeError: set_image() takes 1 positional argument but 2 were given

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

Traceback (most recent call last):
  File "C:\Users\atill\AppData\Local\Programs\Python\Python36\lib\site-packages\discord\ext\commands\bot.py", line 846, in process_commands
    yield from command.invoke(ctx)
  File "C:\Users\atill\AppData\Local\Programs\Python\Python36\lib\site-packages\discord\ext\commands\core.py", line 374, in invoke
    yield from injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\atill\AppData\Local\Programs\Python\Python36\lib\site-packages\discord\ext\commands\core.py", line 54, in wrapped
    raise CommandInvokeError(e) from e
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: set_image() takes 1 positional argument but 2 were given

I'm not sure how to make it so it is in an embed aswell

Answer 1

我对您的个人建议是使用https://meme-api.herokuapp.com/gimme/dankmemes 来拉动模因。如果您有兴趣添加标题，请使用此命令为您的嵌入添加标题：

title = res['data']['children'][random.randint(0,25]["data"]["title"]I 

Answer 2

@client.command(pass_context=True)
async def meme(ctx):
    embed = discord.Embed(title="", description="")

    async with aiohttp.ClientSession() as cs:
        async with cs.get('https://www.reddit.com/r/dankmemes/new.json?sort=hot') as r:
            res = await r.json()
            embed.set_image(url=res['data']['children'] [random.randint(0, 25)]['data']['url'])
            await ctx.send(embed=embed)

Answer 3

如错误中所述，函数 set_image(url) 仅接受 1 个参数，而您给了它 2 个参数。对于嵌入消息，请查看 this 线程。
