如何检查 discord.py 中的文件扩展名

how to check for file extension in discord.py

我正在创建一个 python discord 机器人,我有一个功能,如果在某个频道发送消息, 它随机发出一个响应,一切正常,但我想限制机器人仅在发送的消息包含 png、jpg 或 jpeg 文件时做出反应

这里是代码(寻找底部的 if str(message.channel) 语句):

@client.event
async def on_message(message):
    await client.process_commands(message)
    if str(message.channel) not in restr:
            if message.content == ".sabaton":
                random.seed(time.time())
                randnum = random.randint(0, len(songs) - 1)
                await message.channel.send(file=discord.File(songs[randnum]))
            elif message.content == ".time":
                await message.channel.send(f"Current time is {time.localtime()}")
            elif message.content == ".pmsh":
                await message.channel.send(help)
            if client.user.mention in message.content.split():
                await message.channel.send('Дарова гандон(иха),мой префикс "."')
    if str(message.channel) == "творчество":
        random.seed(time.time())
        rn3 = random.randint(1,2)
        if rn3 == 1 and message.author.bot == False:
            await message.channel.send("Заебись творчество")
        elif rn3 == 2 and message.author.bot == False:
            await message.channel.send("Фигня творчество")

您可以使用以下条件进行限制:

if message.attachments[0].url.endswith('PNG') or message.attachments[0].url.endswith('JPG') or message.attachments[0].url.endswith('JPEG'):
    pass
else:
    pass

根据您的内容更改通行证。

discord.py 中的附件在其 content_type 属性中包含有关其文件类型的信息。这也有望使代码更清晰!

除了访问,@Sofi的逻辑仍然适用:

for attachment in message.attachments:
    if attachment.content_type in ('image/jpeg', 'image/jpg', 'image/png'):
       # Your Logic Here

如果你只需要检查某物是否是图片,你的代码可以更简单:

for attachment in message.attachments:
    if 'image' in attachment.content_type:
         # Your Logic Here!
