郵件擴充套件

在開發過程中，很多應用程式都需要通過郵件提醒使用者，Flask的擴充套件包Flask-Mail通過包裝了Python內建的smtplib包，可以用在Flask程式中傳送郵件。

Flask-Mail連線到簡單郵件協議（Simple Mail Transfer Protocol,SMTP）伺服器，並把郵件交給伺服器傳送。

設定郵箱授權碼

如下示例，通過開啟 QQ 郵箱驗證 SMTP 服務設定，傳送郵件：

#coding:utf-8
from flask import Flask,render_template
from flask_mail import Mail, Message
from threading import Thread


app = Flask(__name__)
# 配置郵件：伺服器／埠／安全套接字層／郵箱名／授權碼
app.config['MAIL_SERVER'] = "smtp.126.com"
app.config['MAIL_PORT'] = 465
app.config['MAIL_USE_SSL'] = True
app.config['MAIL_USERNAME'] = "
 
[email protected]"
app.config['MAIL_PASSWORD'] = "19940414"
app.config['MAIL_DEFAULT_SENDER'] = 'FlaskAdmin<[email protected]>'

mail = Mail(app)

def async_send_email(app, msg):
    with app.app_context():
        try:
            mail.send(msg)
        except Exception as e:
            print e


def send_email_thread(subject, to, content):
    msg = Message(subject=subject, recipients=[to], body=content)
    thread = Thread(target=async_send_email,args=(app, msg))
    thread.start()
    return thread


@app.route('/')
def index():
    return '<a href="%s">傳送郵件</a>' % url_for('send_email')


@app.route('/send_email')
def send_email():
    send_email_thread('我是郵件主題', to='
 
[email protected]', content='我是郵件內容哈哈')
    return '傳送中...'

if __name__ == '__main__':
    app.run()
