Python Flask异步发送邮件实现方法解析

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
