Question

我正在尝试在symfony中创建一个新页面，但我无法访问它

这是我的档案

<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;

class About extends Controller

{
    /**
     * @Route("/about")
     */
    public function aboutAction()
    {
        return new Response(
            '<html><body>This page is about ME</body></html>'
        );
    }
}

当我使用php bin/console debug:router它显示名称：app_about_about（我不明白为什么它有这个名字）和路径：/ about。但是当我尝试加载页面时，我收到404错误

Answer 1

导入后尝试：

use Symfony\Component\HttpFoundation\Response;

只需将您的文件重命名为./MyBundle/Controller/AboutController.php并重命名该类：

SELECT 
    runtable.operation,
    pareto.failure,
    COUNT(CASE WHEN MONTH(runtable.time) = 1 THEN 1 else NULL end) as 'Jan',
    COUNT(CASE WHEN MONTH(runtable.time) = 2 THEN 1 else NULL end) as 'Feb',
    COUNT(CASE WHEN MONTH(runtable.time) = 3 THEN 1 else NULL end) as 'Mar',
    COUNT(CASE WHEN MONTH(runtable.time) = 4 THEN 1 else NULL end) as 'Apr',
    COUNT(CASE WHEN MONTH(runtable.time) = 5 THEN 1 else NULL end) as 'May',
    COUNT(CASE WHEN MONTH(runtable.time) = 6 THEN 1 else NULL end) as 'Jun',
    COUNT(CASE WHEN MONTH(runtable.time) = 7 THEN 1 else NULL end) as 'Jul',
    COUNT(CASE WHEN MONTH(runtable.time) = 8 THEN 1 else NULL end) as 'Aug',
    COUNT(CASE WHEN MONTH(runtable.time) = 9 THEN 1 else NULL end) as 'Sep',
    COUNT(CASE WHEN MONTH(runtable.time) = 10 THEN 1 else NULL end) as 'Oct',
    COUNT(CASE WHEN MONTH(runtable.time) = 11 THEN 1 else NULL end) as 'Nov',
    COUNT(CASE WHEN MONTH(runtable.time) = 12 THEN 1 else NULL end) as 'Dec',
    COUNT(pareto.failure) as 'Total year'
FROM 
    runtable
    JOIN pareto 
        ON pareto.run_id = runtable.id
WHERE
    runtable.time BETWEEN '2016-01-01 00:00:00' AND '2016-12-13 23:59:59'     
    AND runtable.operation IN ('d','hr')
GROUP BY 
    runtable.operation, pareto.failure
;

我认为你应该试试路线名称。您还应该按AboutController重命名控制器。

 /**
 * @Route("/about", name="about_page")
 */

无法在symfony
