Question

我尝试将Sonata媒体与Sonata Formatter集成在一起，并且效果很好，但是我有两个问题。

我可以限制文件大小吗？
为什么它不运行MIME类型验证？

我跟踪了奏鸣曲格式程序代码，并在CkeditorAdminController :: uploadAction（https://github.com/sonata-project/SonataFormatterBundle/blob/4.x/src/Controller/CkeditorAdminController.php#L93）中看到控制器未检查表单是否有效，也未检查媒体是否有效。

另一方面，如果在上传时发生错误，则ckeditor仅显示服务器返回的错误页面，但不会再次显示输入文件小部件。

我终于设法使它成为扩展默认和自定义CkeditorAdminExtension的控制器

namespace MediaBundle\Admin;

use Sonata\AdminBundle\Admin\AdminInterface;
use Sonata\AdminBundle\Route\RouteCollection;
use Sonata\FormatterBundle\Admin\CkeditorAdminExtension;

/**
 * Adds browser and upload routes to the Admin.
 *
 * @author Kévin Dunglas <kevin@les-tilleuls.coop>
 */
// we override routing definitions
class CustomCkeditorAdminExtension extends CkeditorAdminExtension
{
    public function configureRoutes(AdminInterface $admin, RouteCollection $collection)
    {
        $collection->add('ckeditor_browser', 'ckeditor_browser', [
            '_controller' => 'MediaBundle:CustomCkeditorAdmin:browser',
        ]);

        $collection->add('ckeditor_upload', 'ckeditor_upload', [
            '_controller' => 'MediaBundle:CustomCkeditorAdmin:upload',
        ]);
    }
}

控制器：

namespace MediaBundle\Controller;


use Sonata\FormatterBundle\Controller\CkeditorAdminController;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\HttpFoundation\Response;

class CustomCkeditorAdminController extends CkeditorAdminController
{
    CONST MAX_IMAGE_FILE_SIZE = 200 * 1024; // 200 K
    CONST VALID_IMAGE_MIME_TYPES = ['image/pjpeg', 'image/jpeg', 'image/png', 'image/x-png'];

    public function uploadAction()
    {
        $request = $this->get('request_stack')->getCurrentRequest();

        if($request->isMethod('POST')){
            $file = $file = $request->files->get('upload');

            if($file instanceof UploadedFile){
                if($file->getSize() > self::MAX_IMAGE_FILE_SIZE){
                    return new Response('Too big file');
                }

                if(!in_array($file->getMimeType(), self::VALID_IMAGE_MIME_TYPES)){
                    return new Response('File is not a valid image');
                }
            }
        }

        return parent::uploadAction();
    }
}

最后在参数.yml中覆盖扩展参数

parameters:
    sonata.formatter.ckeditor.extension.class: "MediaBundle\\Admin\\CustomCkeditorAdminExtension"

限制将Sonata媒体与Sonata格式化程序ckeditor集成的图像的文件大小
