Flask-Mail用outlook邮箱发送邮件

安装所需库

pip install flask-mail

写mail配置参数

MAIL_SERVER = 'smtp.office365.com'  # 邮箱服务商提供的smtp服务器
MAIL_USERNAME = 'flask_restful_test@outlook.com'  # 邮箱地址
MAIL_PASSWORD = 'flask_restful_mail'  # 邮箱密码，某些邮箱需使用客户端授权码
MAIL_PORT = 587  # smtp端口，默认为25
MAIL_USE_TLS = True  # 是否用TLS加密，outlook需要，其他邮箱不一定
MAIL_DEFAULT_SENDER = ('FlaskRestful', MAIL_USERNAME)  # 可迭代二元对象:(发送者姓名，发送者邮箱)，也可只有一外发送邮箱
# MAIL_DEFAULT_SENDER = MAIL_USERNAME

app注册好邮箱参数后，用多线程发送邮件

from concurrent.futures.thread import ThreadPoolExecutor

executor = ThreadPoolExecutor(1)  # 线程池

# 发送异步邮件函数需要放到app上下文中才能正确发送
def send_async_mail(app, msg):
    with app.app_context():
        mail.send(msg)

def send_mail(email: str = None, token: str = None):
    print('发送邮件中...')
    app = PUBLIC_VARIABLES['app']
    if email and token:
        msg = Message(subject='验证您的邮箱', recipients=[email, ])
        msg.html = f'''
        <span>点击下面的链接验证您的邮箱：</span>
        <br>
        <a href=#>点我验证</a>
        <p>如果上面的链接无法点击，请复制下面的链接到浏览器中打开：</p>

        <br><span>(链接有效期为5分钟，只能访问一次)</span>
        '''
        executor.submit(send_async_mail, app, msg)
    else:
        abort(400, error='验证邮件发送失败')
