            if user.check_password(password):
                session['user'] = username
                # session['id'] = id
                session.permanent=True
                return redirect(url_for('index'))  # 返回到首页
            else:
                return u'password error'
        else:
            return u'error username or password' #输出错误

　　1.更新User对象，设置对内的_password

       2.编写对外的password

       3.密码验证：

       4.登录验证：
