工作中需要及时解决线上的 bug，所以，及时获取 log 中的 warning，error 是非常有必要的。

14 log_format = "%(name)s\t%(asctime)s\t%(pathname)s\t[line:%(lineno)d]\t %(levelname)s\t %(message)s"
15 formater = logging.Formatter(log_format)

17 # 存入文件的日志
18 handler = logging.handlers.TimedRotatingFileHandler(logger_location, "midnight", 1, days, encoding="utf-8")
19 handler.suffix = "%Y%m%d"
20 handler.setFormatter(formater)
21 logger.addHandler(handler)

25 "log error", credentials=(send_email, authority_password),secure=())
26 sh.setLevel(logging.ERROR)
27 sh.setFormatter(EncodingFormatter('%(name)s\t%(asctime)s\t%(pathname)s\t[line:%(lineno)d]\t %(levelname)s\t %(message)s', encoding='utf-8'))

这里有两个坑，但是代码里应该都已经解决了。
- 邮件发送中文的坑，用 EncodingFormatter 解决；
-
邮箱的密码不是登录密码，而是授权码。首先需要打开邮箱的客户端授权，然后设置授权码。
