RuntimeError：超时上下文管理器应该在任务中使用

Question

新手上路，请多包涵

背景：我正在托管一个烧瓶服务器和一个不和谐的客户端

flask 服务器只需要将来自客户端的消息传递给 discord，并将来自 discord 的消息传递给客户端。

I am getting the error when I call loop.run_until_complete(sendMsg(request)) I have tried wait_for in sendMsg and wait_for loop.run_until_complete()

我到处都看过，但没有找到任何东西，所以我们将不胜感激。

代码：

 import discord
import json
import os
import asyncio
from flask import Flask, request, render_template
from async_timeout import timeout
from threading import Thread
from time import sleep

client = discord.Client()
messages = []
app = Flask(__name__)

def startClient():
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)
    client.run('token')

#
# Discord Events
#
@client.event
async def on_ready():
    print('Discord Client Ready')

@client.event
async def on_message(message):
    global messages
    message.append(message)

#
# Flask Stuff
#
async def sendMsg(request):
    await client.send_message(discord.Object('channel id'), request.form['message'])

@app.route("/chat/", methods=['GET', 'POST'])
def chatPage():
    global messages

    if request.method == 'GET':
        return render_template('main.html')

    elif request.method == 'POST':
        loop = asyncio.new_event_loop()
        loop.run_until_complete(sendMsg(request))
        return ''

@app.route("/chat/get", methods=['GET'])
def chatGet():
    return json.dumps(messages[int(request.args['lastMessageId']):])

# Start everything
os.environ["WERKZEUG_RUN_MAIN"] = 'true'
print('Starting discord.py client')
Thread(target=startClient).start()
print('Starting flask')
app.run(host='0.0.0.0', debug=True)
