Flask不会记录日志-未创建日志文件

Question

当我运行Flask应用程序时 未创建用于正常日志记录的日志文件 日志也看不到。 Flask应用程序

from flask import Flask
from apscheduler.scheduler import Scheduler
import atexit
import threading
import time
import logging

app = Flask(__name__) #flask app

base_dir_app_log="/Users/test/Downloads/logs/"


 @app.route("/", methods=['GET'])
 def hello():
     return "Hello World!"


if __name__ == '__main__':
    log_dir = os.path.join(base_dir_app_log,"logs/webmonitoring")
    logfile = os.path.join(log_dir, "Webmonitoring_flask" + datetime.now().strftime('_monitoring_log_%Y_%m_%d_%I_%M_%S.log'))
    logging.basicConfig(format='%(asctime)s:%(levelname)s:%(message)s', datefmt='%m/%d/%Y %I:%M:%S %p', filename=logfile, level=logging.INFO)
sprint ('-------------------------------- START ---------------------------------')
    logging.info ('< --------- START ---------------------- >')




    app.run()
