【英文标题】：Asyncio and Discord.py Timeout context manager should be used inside a task

【问题描述】：

我正在为不和谐的女巫使用 asynco 制作一个 rule34 机器人我正在使用 getImages() 函数，如果 r34 等于 rule34.Rule34(my current loop) 则应该可以使用

我的代码

import discord
import rule34
import nest_asyncio

nest_asyncio.apply()
client = discord.Client()

class bot:
    def __init__(self, message):
        client = discord.Client()
        self.r34 = rule34.Rule34(client.loop)
        self.message = message

    async def send(self, message): #retrives and sends the image
        post = await self.r34.getImages(singlePage=True, OverridePID=1, tags=message.content.split()[1:]) #retrives rule34 object
        print(post)


@client.event
async def on_message(message):
    if message.content.startswith("?p"): #if it's requesting rule34
        post = bot(message)
        await post.send(message)

client.run('MY TOKEN')

输出

Ignoring exception in on_message

    raise RuntimeError('Timeout context manager should be used '

我取消程序时的输出

【参考方案1】：

客户不应该是commands.Bot 而不是discord.Client

编辑：我知道这不是“答案”，但我没有足够的代表来添加评论。

【讨论】：

no commands.Bot 用于为 bot discord 设置命令。Client 是网络中使用的东西

哦。不知道
