使用async await异步执行邮件发送的任务
keywords:email,sanic
- 异步发邮件
- 支持html,html内嵌图片,附件
app.config.update({
'MAIL_SENDER': < 你的发送邮箱 >,
'MAIL_SENDER_PASSWORD': < 你的密码 >,
'MAIL_SEND_HOST': < 邮箱服务器地址 >,
'MAIL_SEND_PORT': < 端口 >,
'MAIL_TLS': < 是否使用TLS >,
'MAIL_START_TLS': < 是否启动TLS,注意与MAIL_TLS冲突 >
})和其他sanic插件一致有两种初始化方法:
- 使用
Sanic_Mail(app)初始化. - 先实例化
sm=Sanic_Mail()再初始化sm.init_app(app)
发送邮件的方法有两个:
- 协程
send_email - 方法
send_email_nowait
其中send_email_nowait意为将任务交给协程发送而不等待发送完毕,同时会返回发送的task.
这个两个方法除了在Sanic_Mail实例上绑定外也会被绑定在app.ctx对象上
在蓝图中或者比较复杂的项目中,app对象可以通过回掉函数的参数request上的app字段上获取到
request.app.ctx.send_email(xxxx)-
html邮件中的图片
html邮件中可以插入图片,不过要求其中的cid为图片名去掉后缀的结果.
