Laravel学习第一天（创建laravel项目、路由、视图、blade模板）

创建laravel项目

composer create-project laravel/laravel learnlv 4.1.*

查看帮助：composer create-project 

 

使用artisan工具

生成key:php artisan key:genrate，更多命令见：http://blog.luoyunshu.com/laravel-cheatsheet

 

路由

route.php：

<span class="pun"><span class="pln">php</span></span>

 

<span class="com">/*</span>

<span class="com">|--------------------------------------------------------------------------</span>

<span class="com">| Application Routes</span>

<span class="com">|--------------------------------------------------------------------------</span>

<span class="com">|</span>

<span class="com">| Here is where you can register all of the routes for an application.</span>

<span class="com">| It's a breeze. Simply tell Laravel the URIs it should respond to</span>

<span class="com">| and give it the Closure to execute when that URI is requested.</span>

<span class="com">|</span>

<span class="com">*/</span>

 

<span class="com">//向控制器传递参数，Route::get('/{id}')</span>
