Attention:

Get data type bytes in 1.redis, type conversion is required for comparisons such as CAPTCHA comparisons

if str (self.session['code'].lower (), encoding="UTF8" )! = self.get_argument ('code'). Lower ():                status['  Status'] = False                status['error'" Verification Code Error "

Or convert the accepted data to the bytes type

2. Store the data if other types

Needs to be performed using eval when used, which is the original string to the data type
