在Symfony Commandline上使用ContainerAwareCommand我想模拟文件上传，以便调用以下方法：
getch现在我想了解方法getche的行为方式，以便创建以下namespace AppUserBundle\Services;
use PcMagas\AppImageBundle\Filters\Crop\CropFilter;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Imagine\Image\ImageInterface;
use PcMagas\AppImageBundle\Filters\Resize\ResizeToLimitsKeepintAspectRatio;
use PcMagas\AppImageBundle\Filters\Resize\ResizeParams;
use PcMagas\AppImageBundle\Loader\ImageLoaderInterface;
use PcMagas\AppImageBundle\Saver\SaverInterface;
use Imagine\Image\Box;
class ProfileImageGenerator implements UploadedFileProcessor
{
const CROP_PARAMS='crop';
/**
* @var CropFilter
*/
private $crop=null;
/**
* @var ThumbnailFilterLoader
*/
private $thumbnail=null;
/**
* @var ResizeParams
*/
private $resizeParams=null;
/**
* @var ImageLoaderInterface
*/
private $imageLoader=null;
/**
* @var SaverInterface
*/
private $imageSaver=null;
public function __construct(CropFilter $crop,
ResizeToLimitsKeepintAspectRatio $thumbnail,
ImageLoaderInterface $imageLoader,
SaverInterface $imageSaver,
$thumbnailWidth,
$thumbnailHeight
){
$this->crop=$crop;
$this->thumbnail=$thumbnail;
$this->imageLoader=$imageLoader;
$this->imageSaver=$imageSaver;
if($thumbnailWidth>0 && $this->thumbnailHeight>0){
$this->resizeParams= new Box($thumbnailWidth,$thumbnailHeight);
}
}
/**
* {@inheritDoc}
* @see \AppUserBundle\Services\UploadedFileProcessor::process()
*/
public function process(UploadedFile $f, array $params)
{
$image=$this->openUploadedFileAsImageInterface($f);
//I implement in such a manner to provide extra prossessings over thumbnail image
if(isset($params[self::CROP_PARAMS])){
$image=$this->crop->apply($image, $params[self::CROP_PARAMS]);
}
if($this->resizeParams){
$image=$this->thumbnail->apply($image,$this->resizeParams);
}
return $this->generateFileFromImageInterface($image);
}
/**
* @param UploadedFile $f
* @return ImageInterface
*/
private function openUploadedFileAsImageInterface(UploadedFile $f)
{
return $this->imageLoader($f->getContents());
}
/**
* @param ImageInterface $image
* @return Symfony\Component\HttpFoundation\File
* @throws RuntimeException
*/
private function generateFileFromImageInterface(ImageInterface $image)
{
$tmpName=tempnam(sys_get_temp_dir()).'.png';
return $this->imageSaver->save($image);
}
}
以模拟文件上传：
process但我仍然坚持如何从文件系统映像创建一个Uploadedfile，以便查看图像是否有效？你是否知道如何做到这一点？
答案 0 :(得分：3)
你看过Symfony Api Documentation吗？
__construct(string $path, string $originalName, string|null $mimeType = null, int|null $size = null, int|null $error = null, bool $test = false)
=＆GT;
new UploadedFile($path, $originalName, $mimeType, $size, $error, $test);
现在，您可以插入从命令参数获取的路径并通过
