Discord bot从所选文件中发送随机图像 [英] Discord bot to send a random image from the chosen file

问题描述

我正在制作一个不和谐的bot，它会随机选择与python文件(cats.py)位于同一目录(Cats)中的一个或多个图像.这是我的代码现在的样子:

  Cats = os.path.join(os.path.dirname(__ file__)，"/images")@ client.command()异步def cat(ctx，** kwargs):等待ctx.send(choice(Cats)) 

我没有收到任何错误.该机器人已联机，当我使用〜cat对其进行ping操作时，它会吐出随机字母.我知道我的问题与异步(可能是kwargs)和等待线有关，但是无法确切指出问题所在.我是Python编程机器人的新手，所以我可能忽略了一个愚蠢的错误，因此不胜感激！

解决方案

一些与您的代码有关的项目.

1. Cats = os.path.join(os.path.dirname(__ file__)，"/images")，仅返回"/images"，由于斜杠开头可能不起作用"/"表示绝对路径，并且您所需的目录不可能在根目录下.如果要使用绝对路径，则需要使用- Cats = os.path.join(os.path.dirname(__ file__)，"images/")-在开始之前加上斜杠文件名.当然，您可以轻松地使用"images/"的相对路径，因为图像与脚本位于同一文件夹中.
2. 等待ctx.send(choice(Cats))-"choice(Cats)"只是一个字符串，选择将返回该字符串中的随机字母.您需要从目录中获取图像/图片以进行选择.您可以使用以下内容创建图像列表- cat_list = [Cats + c for listdir(Cats)中的c] (需要 from os import listdir，path )
3. 您需要使用

   I am making a discord bot that randomly chooses an image (images) which is in the same directory (Cats) as the python file(cats.py). This is what my code looks like right now:

   Cats = os.path.join(os.path.dirname(__file__), "/images")
   
   @client.command()
   async def cat(ctx, **kwargs):
       await ctx.send(choice(Cats))
   

   I am not getting any errors. The bot goes online and when I ping it with ~cat it spits out random letters. I know my issue is with the async (possibly the kwargs) and await line, but cannot pin point exactly what is the issue. I am new to programming bots in Python so there might be a silly mistake that I am overlooking so any lead would be much appreciated!

   解决方案

   Some items regarding your code.

   1. Cats = os.path.join(os.path.dirname(__file__), "/images"), returns just "/images", which probably won't work because the beginning slash "/" indicates an absolute path and your desired directory isn't likely at the root. If you want to use an absolute path you need to use - Cats = os.path.join(os.path.dirname(__file__), "images/") - with a slash after to go before the file name. Of course you could easily just use a relative path of "images/" since images in the same folder as the script.
   2. await ctx.send(choice(Cats)) - "choice(Cats)" is just a string and choice will return a random letter from that string. You need to get the images/pics from the directory to make a selection. You can create a list of images with something like - cat_list = [Cats + c for c in listdir(Cats)] (need from os import listdir, path)
   3. You need to use File to send an image in a message. (need from discord import File)
   4. Not sure what you're doing with **kwargs, so excluded it from this solution.

   Try:

   Cats = path.join(path.dirname(__file__), "images/")
   # Cats = "images/" - to just use the relative path
   cat_list = [Cats + c for c in listdir(Cats)]
   
   
   @bot.command()
   async def cat(ctx):
       await ctx.send(file=File((choice(cat_list))))
