Solve the conflict between APScheduler and uvicorn in fastapi (qbit)

Problem Description

• surroundings

   Ubuntu 20.04
  Python 3.8.5
  APScheduler 3.8.x/3.9.x
  uvicorn 0.15.0 - 0.17.6

• In the above environment, the scheduled task of APScheduler cannot run
• uvicorn 0.14.0 and APScheduler not have this problem
• Under Windows uvicorn and APScheduler with any version, there is no problem

Solution

• Start the timer in the app startup event of ---aedd59f1fb65342fb5f8645fcf5f41a4---

   @app.on_event("startup")
  async def start_scheduler():
    AsyncSched = AsyncIOScheduler(timezone="Asia/Shanghai")
    scheduler.add_job(...)
    scheduler.start()

• See uvicorn can't reload when i use apscheduler and fastapi together
