python发送邮件（flask / smtplib）

基于smtplib

def start():
    # 邮箱服务地址
    mail_host = 'smtp.qq.com'
    # 邮箱用户名
    mail_user = ''
    # 邮箱密码
    mail_pass = ''
    # 邮件发送方邮箱地址
    sender = ''  
    # 邮件接受方邮箱地址，注意这里是一个列表<list>，这意味着你可以写多个邮件地址群发
    receivers = [''] 

    # 设置email信息
    # 设置邮件内容
    message = MIMEText('使用rpa为您发送邮件', 'plain', 'utf-8')
    # 邮件主题       
    message['Subject'] = '邮件测试' 
    # 发送方信息
    message['From'] = sender 
    # 接受方信息     
    message['To'] = receivers[0] 

    # 登录并发送邮件
    try:
        smtpObj = smtplib.SMTP_SSL()
        # 连接到服务器  
        smtpObj.connect(mail_host, 465)
        # 登录
        smtpObj.login(mail_user, mail_pass)
        # 发送信息
        smtpObj.sendmail(sender, receivers, message.as_string())
        # 退出
        smtpObj.quit()
        print('邮件发送成功~')
    except smtplib.SMTPException as e:
        print('error: ' + e)

基于flask

# 使用上下文管理器封装接口
def send_async_email(app, msg):
    with app.app_context():
        try:
            mail.send(msg)
        except Exception as e:
            pass


# 定义邮件体
def send_email(to, subject, template, **kwargs):
    app = current_app._get_current_object()
    msg = Message('标题' + ' ' + '内容',
                  sender=app.config['MAIL_SENDER'], recipients=[to])
    # msg.body = render_template(template + '.txt', **kwargs)
    msg.html = render_template(template + '.html', **kwargs)
    # 多线程发布
    thr = Thread(target=send_async_email, args=[app, msg])
    thr.start()
    return thr
