需求:
1、自动控测电脑有没有注册账号
2、注册账号功能
3、登陆账户三次失败，锁定账户，并禁止登陆（每次登陆失败提示还有几次机会）
4、修改密码功能（第一次先输入旧密码，后两次输入相同的新密码，否则报错提示）
5、可以取款，提现、转账，一次性取款存款转账限额一万五 （开发一半）
6、存款手续费3%,提现手续费5% （未开发）
7、可以预透支金额，限额三万 （还剩一半功能）
8、每月10号为还款日，过期未还，按欠款额5%利息（未开发）
9、还款功能（包括查看欠款金额、还款、还剩计息日） （开发一半）
10、查看个人账户信息(如：用户名、性别、职业、余额) （未开发）
11、查看近三十天账号操作记录（包括登陆次数、取款、存款、转账和操作的时间） （未开发）
12、登陆需要输入验证码 （未开发）
