如何在Python flask中按特定时间间隔发送自动提醒邮件

pip install flask
pip install flask-mail

from flask import Flask
from flask_mail import Mail

app = Flask(__name__)
app.config['MAIL_SERVER'] = 'smtp.example.com'
app.config['MAIL_PORT'] = 587
app.config['MAIL_USE_TLS'] = True
app.config['MAIL_USERNAME'] = 'your-email@example.com'
app.config['MAIL_PASSWORD'] = 'your-email-password'

mail = Mail(app)

pip install apscheduler

from apscheduler.schedulers.background import BackgroundScheduler

scheduler = BackgroundScheduler()

@scheduler.scheduled_job('cron', hour=9)
def send_reminder_email():
    # 在这里编写发送邮件的代码
    # 可以使用Flask-Mail库发送邮件

scheduler.start()

from flask_mail import Message

@app.route('/send_email')
def send_email():
    msg = Message('Reminder', sender='your-email@example.com', recipients=['recipient@example.com'])
    msg.body = 'This is a reminder email.'
    mail.send(msg)
    return 'Email sent successfully.'
