Flask 日志邮件发送 客户端授权密码验证错误

最近在使用flask的日志邮件发送功能，就是程序出现问题的时候，可以通过邮件发送到指定的邮箱，当时使用的是QQ邮箱的

基本上会有如下的错误

smtplib.SMTPAuthenticationError: (535, b'Error: authentication failed')

 

smtplib.SMTPServerDisconnected: Connection unexpectedly closed

 

Connection unexpectedly closed: timed out

 

开始的配置如下

ADMINS = ['xxx@126.com']
MAIL_SUBJECT_PREFIX = '[Walkerfree]'
MAIL_SENDER = 'xxx@qq.com'
MAIL_SERVER = 'smtp.qq.com'
MAIL_PORT = 465
MAIL_USE_SSL = True
MAIL_USE_TLS = False
MAIL_USERNAME = 'xxx@qq.com'
MAIL_PASSWORD = '123456'

在测试的时候会遇到超时，但是是这里的问题

mail_handler = SMTPHandler(
        application.config['MAIL_SERVER']
        application.config['MAIL_SENDER'],
        application.config['ADMINS'],
        'application error',
        (
            application.config['MAIL_USERNAME'],
            application.config['MAIL_PASSWORD'],
        )
    )

第一个参数没有传递端口号，可以看源码

self.mailhost, self.mailport = mailhost

有mailhost和mailport，没有端口号怎么能行呢

修改后如下

mail_handler = SMTPHandler(
        (
            application.config['MAIL_SERVER'],
            application.config['MAIL_PORT']
        ),
        application.config['MAIL_SENDER'],
        application.config['ADMINS'],
        'application error',
        (
            application.config['MAIL_USERNAME'],
            application.config['MAIL_PASSWORD'],
        )
    )

报错如下

SMTPServerDisconnected: Connection unexpectedly closed: timed out

最后修改了配置，如下

ADMINS = ['xxx@126.com']
MAIL_SUBJECT_PREFIX = '[Walkerfree]'
MAIL_SENDER = 'xxx@qq.com'
MAIL_SERVER = 'smtp.qq.com'
MAIL_PORT = 25
MAIL_USE_SSL = True
MAIL_USE_TLS = False
MAIL_USERNAME = 'xxx@qq.com'
MAIL_PASSWORD = '123456'

最后发送成功。客户端授权码的这个需要自己去搞，QQ帮助中心有指引的。
