Flask学习之Flask-mail群发邮件

Flask-mail包装了python标准库中smtplib的扩展能更好的和Flask集成。

#安装flask_mail
pip install flask_mail
export MAIL_USERNAME='mail username'
export MAIL_PASSWORD='mail password'

#!/usr/bin/env python
#-*- coding:utf-8 -*-
from flask_mail import Mail, Message
from flask import Flask
import os
#
app = Flask(__name__)
#定义邮箱地址文件
mail_file = file('/root/mail.txt')
#读取文件中所有的邮箱地址
mail_add = mail_file.read()
#将邮箱地址去掉换行符添加的列表当中
mail_list = mail_add.split('\n')
#添加Flask-mail smtp的配置
#这里使用126的smtp服务器
app.config['MAIL_SERVER'] = 'smtp.126.com'
app.config['MAIL_PORT'] = 25
app.config['MAIL_USER_TLS'] = True
#通过export把环境变量MAIL_USERNAME添加到env中，这里os.environ.get获取环境变量中的变量。
app.config['MAIL_USERNAME'] = os.environ.get('MAIL_USERNAME')
app.config['MAIL_PASSWORD'] = os.environ.get('MAIL_PASSWORD')
app.config['MAIL_DEBUG'] = True

mail = Mail(app)

msg = Message("hello,perfect world!",sender=''MAIL_USERNAME'',recipients=mail_list)
msg.body = 'hello perfect world'
msg.html = 'HTML body'

with app.app_context():
    mail.send(msg)
