Start Symfony

创建一个路由匹配

# app/config/routing.yml
lucky_number:
    path:     /lucky/number/{count}
    defaults: { _controller: AppBundle:Lucky:number }

然后在对应的路由编写对应的代码

// src/AppBundle/Controller/LuckyController.php
// ...
 
class LuckyController
{

    public function numberAction($count)
    {
        $numbers = array();
        for ($i = 0; $i < $count; $i++) {
            $numbers[] = rand(0, 100);
        }
        $numbersList = implode(', ', $numbers);
 
        return new Response(
            'Lucky numbers: '.$numbersList.''
        );
    }
 
    // ...
}

去/lucky/number/xx测试一下，把xx换为任意数字：
http://localhost:8000/api/lucky/number/7

渲染模板（利用容器）

// src/AppBundle/Controller/LuckyController.php
 
// ...
// --> add this new use statement
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
 
class LuckyController extends Controller
{
    public function numberAction($count)
{
    // ...
 
    /*
    $html = $this->container->get('templating')->render(
        'lucky/number.html.twig',
        array('luckyNumberList' => $numbersList)
    );
 
    return new Response($html);
    */
 
    // render: a shortcut that does the same as above 快捷方法
    return $this->render(
        'lucky/number.html.twig',
        array('luckyNumberList' => $numbersList)
    );
}
}
