本文探讨了如何在Flask应用中利用Python的threading模块来实现多线程处理，以提高Web服务的并发性能。通过创建并启动线程，可以将耗时任务分离，保持主线程的响应速度，确保用户请求得到及时处理。

from threading import Thread

from flask import current_app, render_template
from flask_mail import Message

from app import mail


def asyn_send_mail(app, msg):
    with app.app_context():
        try:
            mail.send(msg)
        except Exception as e:
            pass


def send_mail(to, subject, template, **kwargs):
    # msg=Message('测试邮件',sender='guaosi@vip.qq.com',body='test',recipients=['624249423@qq.com'])
    msg = Message(current_app.config['MAIL_SUBJECT_PREFIX'] + ' ' + subject,
                  sender=current_app.config['MAIL_USERNAME'], recipients=[to])
    msg.html = render_template(template, **kwargs)
    app = current_app._get_current_object()
    thread = Thread(target=asyn_send_mail, args=[app, msg])
    thread.start()
