未关闭的客户端会话

Question

我正在尝试向discord机器人发出命令，它从这个脚本中获取列表，并从它们中随机发送一个。我大约一个月前开始用Python编写程序，所以这对我来说是相当困难的。

问题是，当我运行此脚本时出现错误:未关闭的客户端会话client_session：

import asyncpraw
import asyncio
from aiohttp import ClientSession

async def get_meme(posses=100):
    posts = []
    async with ClientSession() as session:
        async for subreddit in subreddits:
            sub = await reddit.subreddit(subreddit).top(limit=posses, time_filter="week")
            for post in sub:
                await posts.append(post.url)
        await session.close()
        return posts


async def main():
    task = asyncio.create_task(get_meme())
    reddit_memes = await task
    print(reddit_memes)

我看得出来你在尝试做一个表情包命令。我会推荐asyncpraw的reddit API。下面是一个简单的例子：

import asyncpraw #Register at https://www.reddit.com/prefs/apps

reddit = asyncpraw.Reddit(client_id = 'client_id',
                     client_secret = 'client_secret',
                     username = 'username',
                     password = 'password',
                     user_agent = 'user_agent')


@client.command()
async def meme(ctx):
  subreddit = await reddit.subreddit("memes")
  all_subs = []
  top = subreddit.top(limit = 100)
  async for submission in top:
      
    all_subs.append(submission)
    
  random_sub = random.choice(all_subs)
  name = random_sub.title
  url = random_sub.url
  link = random_sub.permalink
  embed = discord.Embed(title=name color=ctx.author.color)
  embed.set_image(url=url)
  await ctx.send(embed=embed)
