如何为我的 discord.py 机器人获取随机 subreddit 图像?

问题描述

我正在异步 python 中制作一个不和谐的机器人.我希望机器人在我执行命令(前缀！)示例时发布 随机 图片！meme.这会从 subreddit 中调出一张随机图片，在这种情况下是 memes subreddit.我已经开始了我想要的，但我需要随机 subreddit 位的帮助.

I am making a discord bot in async python. I want the bot to post a random picture when I do a command (prefix !) example !meme. This would bring up a random picture from a subreddit, in this case the memes subreddit. I have made the start to what I want, but I need help with the random subreddit bit.

import discord
import praw
from discord.ext import commands

bot = commands.Bot(description="test", command_prefix="!")

@bot.command()
async def meme():
    await bot.say(---)   
    #--- WOULD BE THE REDDIT URL
    bot.run("TOKEN")

我将如何使用 discord.py 和 PRAW 来做到这一点?

解决方案

以下代码将从 memes subreddit 中获取随机帖子.目前它会从热门版块的前 10 篇帖子中随机提交.

The below code will fetch a random post from the memes subreddit. Currently it picks a random submission from the top 10 posts from the hot section.

import praw
import random
from discord.ext import commands

bot = commands.Bot(description="test", command_prefix="!")

reddit = praw.Reddit(client_id='CLIENT_ID HERE',
                     client_secret='CLIENT_SECRET HERE',
                     user_agent='USER_AGENT HERE')

@bot.command()
async def meme():
    memes_submissions = reddit.subreddit('memes').hot()
    post_to_pick = random.randint(1, 10)
    for i in range(0, post_to_pick):
        submission = next(x for x in memes_submissions if not x.stickied)

    await bot.say(submission.url)

bot.run('TOKEN')
