 Laravel5.2目录结构及composer.json文件解析

使用artisan命令创建控制器

1.控制台环境，切换到项目根目录下并输入命令：php artisan make:controller IndexController，这样就创建好一个控制器

2.但是，通常情况下，我们需要对项目进行分组（比方说前后端分组）。如下图所示，在Controllers目录下新建了一个Admin分组，用于存放后台控制器

php artisan make:controller Admin/IndexController

控制器中的index方法

public function index(){

   return view('admin/index');

}

Route::get('/', function () {
    return view('test');   // 其模板放在resources/views/test.blade.php
});

Route::get('view','AdminViewController@index');   //访问 /view  直接找到Admin下的ViewController下的index方法 
Route::get('/admin/{id}','AdminIndexController@index');  // 携带id

  // 命名路由

  第一种：

   Route::get('/test',['as'=>'profile',function(){
     return route('profile'); // http://blog.com/test
   }]);

   第二种：

   Route::get('/test', [
        'as' => 'profile', 'uses' => 'AdminTestController@index'
   ]);

   第三种：

   Route::get('/test','AdminTestController@index')->name('profile');

   

   // 路由分组  

   Route::group(['prefix'=>'admin','namespace'=>'Admin'],function(){
       Route::get('index','IndexController@index');
       Route::get('test','TestController@index');

       Route::resource('article','ArticleController');

   });

//后台专用路由 根据前缀和命名空间
Route::group(['prefix'=>'admin','namespace'=>'Admin','middleware' => ['web','admin.login']],function(){
    Route::get('index','IndexController@index');
    //资源控制器  先添加这一行   在用 php artisan make:controller ArticleController
    //  将ArticleController放到Admin目录下 并用php artisan route:list 查看
    Route::resource('article','ArticleController');
});

//中间件的用法  创建admin.login中间件  首先在kernel.php中添加admin.login=>'AppHttpMiddlewareAdminLogin.class'
//然后用php artisan make:middleware AdminLogin
Route::group(['middleware' => ['web']], function () {
    Route::get('admin/login','AdminIndexController@login');
    Route::get('/', function ()    {
        session(['key'=>123]);
        return view('welcome');
    });

    Route::get('user', function () {
        echo session('key');
        return 'user';
    });
});

    protected $routeMiddleware = [
        'auth' => AppHttpMiddlewareAuthenticate::class,
        'auth.basic' => IlluminateAuthMiddlewareAuthenticateWithBasicAuth::class,
        'guest' => AppHttpMiddlewareRedirectIfAuthenticated::class,
        'throttle' => IlluminateRoutingMiddlewareThrottleRequests::class,
        //自定义中间件Adminlogin  目录在Middleware/AdminLogin.php
        //route.php 调用  'middleware' => ['web','admin.login']]
        'admin.login'=> AppHttpMiddlewareAdminLogin::class,
    ];

视图传参

        //第一种方式传参
        $name="ceshi";
        $age = '2';
        return view('mylarvel')->with(array('name'=>$name,'age'=>$age));
        //第二种方式传参
        $data = [
            'name'=> 'ceshi',
            'age' => '4'
        ];
        return view('mylarvel',$data);
        //第三种方式传参
        $data = [
            'name' => 'ceshi',
            'age' => 3
        ];
        $title = "正在学习larvel";
        return view('mylarvel',compact('data','title'));

 laravel中引用css文件

{{asset('/static/css/admin.css')}}
