  • Flask异步发送邮件的方法

    第一步,修改工厂函数,配置邮件参数

    from flask import Flask
    from config import Config
    from flask_sqlalchemy import SQLAlchemy
    from flask_mail import Mail
    
    db = SQLAlchemy()
    mail = Mail()
    
    def create_app():
        app = Flask(__name__)
        app.config.from_object(Config)
        db.init_app(app)
        mail.init_app(app) 

    from .controller import controller app.register_blueprint(controller) return app

    第二步,新建一个线程来发送邮件

    from flask import current_app, render_template
    from flask_mail import Message
    from threading import Thread
    from main import mail
    
    def send_async_email(app, msg):
        with app.app_context():
            mail.send(msg)
    
    def send_email(to, subject, template = 'index', **kwargs):
        app = current_app._get_current_object()
        msg = Message(subject, sender = app.config['MAIL_USERNAME'], recipients = [to])
        msg.html = render_template('{}.html'.format(template), **kwargs)
        thr = Thread(target = send_async_email, args = [app, msg])
        thr.start()
        return thr

    从current_app的_get_current_object()方法拿到应用程序上下文。特此记录一下
