1.先打开文件，
2.创建杂货，
3.对文件进行操作
4.进行循环
5.输入用户名进行判断，
    （1）.用户名是否存在
        (1).存在的话就退出本次循环
    （2）不在的话，
        （1）进行验证，
            （1）验证成功的。
            （2）不成功
                （1）不成功的在进行验证，
                    （1）在定义的字典中，是否存在了，存在的次数不超过3次就进行自加
                    （2）不在定义的字典中，将用户名添加进去，
        (2)用户不存在的
            （1）提示用户不存在，返回
