Django 配置明文密码登录和注册

"""
from django.contrib.auth.models import AbstractUser

自定义UserInfo表并且继承AbstractUser
1.验证密码的时候，check_password 会取出数据库中保存的密码
2.调用mycheck_password ==》 password == 用户输入的密码 ； encoded == 数据库中保存的密码
from django.contrib.auth.hashers import check_password
3.默认的 check_password 会将用输入的密码进行一些列的加密，然后在判断是否跟数据库中的密文密码是否一致，如果一致返回True否者False
  这里我们重写 让UserInfo去调用我们自己写的mycheck_password，删除加密的过程，直接判断密码是否一致
4.注册的时候设置明文需要重写 set_password 取消加密
