使用 flask 和 discord bot 循环导入

Question

我有这两个文件：

main.py

import os
import discord
from keep_alive import keep_alive
client = discord.Client()

my_secret = os.environ['Token']

async def SendMeMessage():
  user = await client.fetch_user('my id')
  await user.create_dm()
  await user.dm_channel.send("Someone needs help")
  
keep_alive()
client.run(my_secret)

keep_alive.py

from flask import Flask
from threading import Thread
#from main import SendMeMessage

app = Flask('')
@app.route('/')
def home():
  #SendMeMessage()
  return "Hello. I am alive!"

def run():
  app.run(host='0.0.0.0', port=8080)

def keep_alive():
  t = Thread(target=run)
  t.start()

我想导入 SendMessage。因此，当有人在 Flask 服务器上发送获取请求时，我想从我的 discord 机器人接收消息。当我实施注释代码时，我陷入错误“循环导入”。

Answer 1

我会将 discord 机器人代码移出 main.py，因此它不再依赖于 keep_alive.

的导入

bot.py:

import os
import discord

client = discord.Client()

async def SendMeMessage():
  user = await client.fetch_user('my id')
  await user.create_dm()
  await user.dm_channel.send("Someone needs help")

keep_alive.py:

from flask import Flask
from threading import Thread
from bot import SendMeMessage

app = Flask('')
@app.route('/')
def home():
  SendMeMessage()
  return "Hello. I am alive!"

def run():
  app.run(host='0.0.0.0', port=8080)

def keep_alive():
  t = Thread(target=run)
  t.start()

main.py:

import os

from keep_alive import keep_alive
from bot import client

my_secret = os.environ['Token']

keep_alive()
client.run(my_secret)

这样，bot.py在keep_alive.py运行的时候就已经完全导入了，所以不再循环导入。

使用 flask 和 discord bot 循环导入

Circular import using flask and discord bot

python

discord
