python flask发送邮件
python flask发送邮件
* SMTPAuthenticationError: (535, ‘Error: authentication failed’)
解决办法：调用163邮箱服务器来发送邮件,我们需要开启POP3/SMTP服务,这时163邮件会让我们设置客户端授权码，这个授权码替代上面代码部分的passwd即可成功发送邮件
安装flask-mail
pip3 install flask-mail总体结构图

异步发送电子邮件
from threading import Thread
def send_async_email(app,msg):
with app.app_context():
mail.send(msg)
def send_email(to,subject,template, **kwargs):
msg = Message(app.config['FLASK_MAIL_SUBJECT_PREFIX']+subject,
sender=app.config['FLASK_MAIL_SENDER'],recipients=[to])
msg.body=render_template(template+'.txt',**kwargs)
msg.html=render_template(template+'.html',**kwargs)
thr = Thread(target=send_async_email,args=[app,msg])
thr.start()
return thr注意：很多Flask扩展都假设已经存在激活的程序上下文和请求上下文。Flask-Mail中的send()函数使用current_app,因此必须激活程序上下文。不过，在不同线程中执行mail.send()函数时，程序上下文要使用app.app_context()人工创建。
