laravel框架任何请求都要经过路由。
public目录下有文件，其访问优先级高于路由。
Route::get('/', function () {return view('welcome');});welcome：视图文件名称。view('welcome', 数组);: 数组参数，带一些数据到视图视图文件加载演示代码：
// test.php<!doctype html><html lang="en"><head><meta charset="UTF-8"><title>加载视图文件测试</title></head><body><div>好好学习，天天向上！</div></body></html>// controller<?phpnamespace App\Http\Controllers;use Illuminate\Http\Request;class Home extends Controller{public function test(){return view('test');}}// 路由Route::get('/', function () {return view('test');});
演示效果图：
图1：
图2成功访问：
Route::get('路由地址', '控制器类@类方法名称');控制器类：默认是Controllers目录下，如果还有下级目录要带上。如Route::get('/admins/article/list', 'admins\Article@lists');artisian文件目录php artisan make:controller Homephp artisan make:controller 目录名/文件名使用命令创建成功图：
视图文件加载演示代码：

演示效果图：
1、本节课学会了如何在MVC模型框架中把视图view展示出来。
2、了解如何把控制器映射到路由。
3、加强了一下原生的数据库增删改查操作
总之收获很多。
