Python + Flask + Discord:如何通过flask端点通过discord发送消息?

问题描述

我正在尝试发送一条不和谐的消息，通过 Flask 端点激活

I'm trying to send a message with discord, activated through a Flask endpoint

我在调用 http://127.0.0.1:5000/send

RuntimeError: There is no current event loop in thread 'Thread-4'.

我有以下(最少的)代码

I have the following (minimal) code

import discord
from flask import Flask, jsonify

async def my_background_task():

  for message in ['a', 'b']:
    await client.wait_until_ready()
    channel = client.get_channel(CHANNEL_ID)
    await channel.send(message)

  await client.close() 

def sendMessages():
  client = discord.Client()
  client.loop.create_task(my_background_task())
  client.run('SECRET')

app = Flask(__name__)


@app.route('/send')
def send():
  sendMessages()

推荐答案

也许您应该考虑使用 webhook 而不是机器人.这是一个简单的示例，您应该对其实现烧瓶.

Maybe you should consider using webhooks instead of a bot. Here is a simple example you should implement flask to it.

import requests #dependency

url = "<your url>" #webhook url, from here: https://i.imgur.com/aT3AThK.png

data = {}
#for all params, see https://discordapp.com/developers/docs/resources/webhook#execute-webhook
data["content"] = "message content"
data["username"] = "custom username"

#leave this out if you dont want an embed
data["embeds"] = []
embed = {}
#for all params, see https://discordapp.com/developers/docs/resources/channel#embed-object
embed["description"] = "text in embed"
embed["title"] = "embed title"
data["embeds"].append(embed)

result = requests.post(url, json=data, headers={"Content-Type": "application/json"})

try:
    result.raise_for_status()
except requests.exceptions.HTTPError as err:
    print(err)
else:
    print("Payload delivered successfully, code {}.".format(result.status_code))
