Symfony4: Image无法保存

Question

我已经从Symfony 3.4更新到4.0，并验证了操作。图片保存功能显示"完成"，但是没有保存图片。因为保存目的地被设置为web/uploads，在image .php中，我将图像目录路径从web更改为public，但它没有改变。还有什么需要更改的吗?

ImageController.php

    public function saveAction(Request $request)
    {
        $response = new Response();
        $imageService = $this->get("admin.imageService");
        if ($token === $imageService->getImageToken($staffId, $uniq)) {
            try {
                $imageService->saveImage($image);
                // Normal termination parameters #This is required for onComplete to fire on Mac OSX
                $msg = $this->container->getParameter('uploadify_success');
            } catch (Exception $e) {
                $msg = $e->getMessage();
                $response->setStatusCode(400);
            }
        } else {
            $msg = 'Access is illegal.';
            $response->setStatusCode(400);
        }
        $response->send();

ImageService.php

    public function saveImage(Image $image)
    {
        // Set the extension (already set when saving from an email attachment)
        $ext = $image->getImageExtension();
        if (!$ext && $image->getFileUpload()) {
            $ext = $image->getFileUpload()->guessExtension();
            $image->setImageExtension($ext);
        }
        // save
        $this->entityManager->persist($image);
        $this->entityManager->flush();
    }

Image.php

    private function getUploadRootDir()
    {
        // Absolute path to the location to save the uploaded file
        return __DIR__.'/../../../../../../public/'.$this->getUploadDir();
    }
    /**
     * Returns the image directory name
     *
     * @return string
     */
    private function getUploadDir()
    {
        return 'uploads';
    }

你应该用projectDir代替你的getUploadRootDir()和危险的../../

看一下这篇文章Symfony 4，从一个自定义类(不是控制器类)中获得项目的根路径的详细说明
