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
