前几天小编写了一篇MVC框架简述,大概笼统的说了一下,这次小编结合着Laravel框架给大家具体演示。

开发坏境:Laravel版本: 5.0.22php版本:    5.5.11mysql版本: 5.6.16

通过之前的文章,我们清楚的知道,MVC框架。M是数据存储,V是视图展现,C负责数据处理,连接V和M。在配置好Laracel环境以后,首先我们来看一下。系统提供给我们一个页面

php artisan serve

启动服务器,访问http://localhost:8000看到laravel的欢迎页

然后我们来看一下路由文件/app/Http/routes.php

Route::get('/', 'WelcomeController@index');Route::get('home', 'HomeController@index');Route::controllers([	'auth' => 'Auth\AuthController',	'password' => 'Auth\PasswordController',]);

通过查看路由,我们可以看到我们访问localhost:8000的时候,默认访问到是WelcomeController的index。这里的WelcomeController就是所谓的Controller。然后我们找到该文件。/app/Http/Controller/WelcomeController.php。

public function index()	{		return view('welcome');	}

明显看到返回一个视图,名字是welcome。然后我们再在视图里面找welcome。视图的目录是/resourse/views/welcome.blade.php。这里blade是一个视图模板。然后我们访问的http://localhost:8000其实就是该视图。画个图表示一下思路吧,这里没有用到M(数据库操作)

看到这里大概应该明白了,下面让我们就动手写一个。

先在增添一个路由,/app/Http/routes.php

Route::get('goofyy','GoofyyController@index');

然后我们再在Controller添加GooyyController文件,这里创建有两种方式创建文件,一个就是手动创建,一个就是终端创建,终端创建方法是

php artisan make:controller GoofyyController

区别是,终端创建的包含一些默认方法。

创建完成后.创建index方法,如果是终端创建,已经包含,修改为,

public function index()    {     return view('GoofyyView')  ;    }

然后在视图里创建GoofyyView.blade.php文件,不写太多,就写一句话吧。

然后我们在网页访问,http://localhost:8000/goofyy  

然后获得如图所示的界面就说明,第一个小实验你就success了。在view的GoofyyView.blade.php模板当中,你可以使用html,js等等,blade模板是Laravel碉碉的功能。

下面就写一个带M(数据操作)的程序。

还是用刚刚新建的文件,

更改Controller里面的GoofyyController.php的index方法。

    public function index() {    $array1 = [      'name' => "Goofyy",        'age' => "22",    ];    return view('GoofyyController',$array1);   //return view('GoofyyController')->with('name'=>'Goofyy')->with('age'=>'22');   }

这里有两种传参的方法,array和with。array相对比较明确些,with在传多个数值的时候,显得很杂乱而且麻烦。
 
然后我们在View里面使用。GoofyyView.blade.php更改如下

在blade模板当中也使用了style样式,碉碉的吧。下一篇文章讲一下blader模板的强大之处
