##python程序 命名为hello.py
 
import os 
from flask import Flask
from flask_mail import Mail
from flask_script import Manager
 
app = Flask(__name__)
 
app.config['MAIL_SERVER'] = 'smtp.126.com'
app.config['MAIL_PORT'] = 25
app.config['MAIL_USE_TLS'] = True
app.config['MAIL_USERNAME'] = os.environ.get('MAIL_USERNAME')

msg.body = 'test body'
msg.html = '<b>test html</b>'
with app.app_context():
  mail.send(msg)
