Python 如何在没有ctrlc的情况下在10秒后立即停止Flask 的使用

我想使用Flask 作为巨 Python 脚本的一部分.我想执行一些命令，然后运行FlaskTM服务器发送文件，并在10秒或更长时间后关闭服务器并继续运行脚本.

在执行Shut_Down函数后，出现一个错误，直到我在终端按下ctrl-c，REST脚本才会执行.以下是我的代码

from flask import send_from_directory, abort 
from flask import Flask
import socket
from flask import request
from flask_apscheduler import APScheduler


hostName= socket.gethostname()
ipAddr= socket.gethostbyname(hostName)
app= Flask(__name__)
app.config["CLIENT_IMAGES"]="photo"

socketio = SocketIO(app)
sched=APScheduler()
counter=0

def shutdown_server():
    func = request.environ.get('werkzeug.server.shutdown')
    if func is None:
        raise RuntimeError('Not running with the Werkzeug Server')    
    func()

@app.route("/")
def index():
    return "Hello World"


@app.route("/get-image/<string:image_name>") 
def get_image(image_name):    
    try:
        return send_from_directory(app.config["CLIENT_IMAGES"], "photo.jpg", as_attachment=True)
        
    except FileNotFoundError:
        abort(404)

if __name__=="__main__":
    sched.add_job(id='Job1',func=shutdown_server, trigger='interval', seconds=5)
    sched.start()
    #app.run()
    #socketio.run(app,host="0.0.0.0", port=4998,allow_unsafe_werkzeug=True)
    app.run(host=ipAddr, port='5000',debug= False) #,use_reloader=False 
    #os.system("start /b python app.py")
    #os.system("python "+ "app.py &" )
counter+=1
print("ALohaaa")

以下是错误:

This typically means that you attempted to use functionality that needed
an active HTTP request. Consult the documentation on testing for
information about how to avoid this problem.
