Flask定时任务

安装

pip install flask_apscheduler

初始化

scheduler.py

from flask_apscheduler import APScheduler
import os

scheduler = APScheduler()

def init_app(app):
  # 防止重复启动
  if os.environ.get("SCHEDULER_LOCK") == "True":
    return
  os.environ["SCHEDULER_LOCK"] = "True"
  scheduler.init_app(app)
  scheduler.start()

app.py

from flask import Flask
import scheduler

app = Falsk(__name__)
scheduler.init_app(app)

if __name__ == "__main__":
  app.run()

实际运行中遇到的问题

RuntimeError: Working outside of application context.

解决方案：

from scheduler import scheduler

def task():
  with scheduler.app.context():
    # do some thing
    pass
