Example Code
from fastapi import FastAPI
def register_init(app: FastAPI) -> None:
@app.on_event("startup")
async def init_connect():
print("init_connect...")
@app.on_event('shutdown')
async def shutdown_connect():
print("shutdown_connect...")
def create_app() -> FastAPI:
app = FastAPI()
register_init(app) # comment this line and uncomment code block blow
return app
app = create_app()
# @app.on_event("startup")
# async def init_connect():
# print("init_connect...")
# @app.on_event('shutdown')
# async def shutdown_connect():
# print("shutdown_connect...")
if __name__ == "__main__":
import uvicorn
uvicorn.run(app='main:app', host="127.0.0.1", port=8010, reload=True, debug=True)Description
Default code only print "init_connect"
uncomment can print "init_connect" and "shutdown_connect".
