这是一篇记录向，记录我后台的学习过程。
如有不正确的地方，请多多指教。
基础知识：
MVC即 Model View Controller
- Model（模型）表示应用程序核心（比如数据库记录列表）。
- View（视图）显示数据（数据库记录）。
- Controller（控制器）处理输入（写入数据库记录）。
（图源https://www.runoob.com/design-pattern/mvc-pattern.html）
当我们浏览一个网页的时候首先会访问到View（视图层）
在我们输入用户名密码之后，会将输入的数据传到Controller（控制器）中，再通过Model（模型）将数据写/读数据库记录列表。
Model（模型）层操作完毕之后，数据更新返回Controller（控制器）。
再次返回View（视图层）。
数据库结构：
id：主键
username：用户名
password：密码
nickname：昵称
email：注册邮箱
status：用户状态（0表示禁用，1表示可用）
super：是否为超级管理员（0表示否，1表示是）//可无
create_time：创建时间
update_time：更新时间
delete_time：软删除时间
Controller层：
//注册 ???public function register() ???{ ???????if (request()->isAjax()) {//判断是否存在ajax请求 ???????????$data = [ ???????????????//传入View视图层中用户输入的数据 ???????????????‘username‘ => input(‘post.username‘), ???????????????‘password‘ => input(‘post.password‘), ???????????????‘conpass‘ => input(‘post.conpass‘),//确认密码 ???????????????‘nickname‘ => input(‘post.nickname‘), ???????????????‘email‘ => input(‘post.email‘) ???????????]; ???????????$result = model(‘Admin‘)->register($data);//将数据传到Model中处理 ???????????if ($result == 1) { ???????????????//注册成功，跳转至登录界面 ???????????????$this->success(‘注册成功‘, ‘http://quantabei.cn/index.php/index/index/login‘);//如果注册成功，自动跳转至登录界面 ???????????} else { ???????????????$this->error($result); ???????????} ???????} ???????return view();//返回View视图层 ???}//登录 ???public function login() ???{ ???????if (request()->isAjax()) { ???????????$date = [ ???????????????"username" => input(‘post.username‘), ???????????????"password" => input(‘post.password‘) ???????????];//传入数据，需要什么就接收什么，达到过滤 ???????????//将数据传入名为Admin的Model下login方法中 ???????????$result = model("Admin")->login($date); ???????????if ($result == 1) { ???????????????$this->success(‘登录成功!‘, ‘http://quantabei.cn/index.php/index/home/index.html‘);//跳转到首页 ???????????} else { ???????????????$this->error($result); ???????????} ???????} ???????return view(); ???}Model层：
