废话不多说，直接上代码：
from flask import Flaskfrom
flask_mail import Mail, Message
app = Flask(__name__)
app.config.update(
#EMAIL SETTINGS
MAIL_SERVER='smtp.qq.com',
MAIL_PORT=465,
MAIL_USE_SSL=True,
MAIL_USERNAME = 'qq号(如：123456)',
MAIL_PASSWORD = 'qq邮箱授权码' )
mail = Mail(app)
@app.route("/")
def index():
msg = Message(subject="helloworld", sender='发送邮箱地址(如：123456@qq.com)', recipients=['接受邮箱地址(如：654321@qq.com)'])
msg.html = "testinghtml"
mail.send(msg)
if__name__ =='__main__':
app.run(debug=True)
