Fatal error: Cannot access protected property Symfony\Component\HttpFoundation\FileBag::$parameters in /var/www/File/src/Webmuch/FileBundle/Entity/File.php on line 66

请求对象:

Symfony\Component\HttpFoundation\FileBag Object
(
    [parameters:protected] => Array
        (
            [file] => Array
                (
                    [0] => Symfony\Component\HttpFoundation\File\UploadedFile Object
                        (
                            [test:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 
                            [originalName:Symfony\Component\HttpFoundation\File\UploadedFile:private] => FLB1.jpg
                            [mimeType:Symfony\Component\HttpFoundation\File\UploadedFile:private] => image/jpeg
                            [size:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 13584
                            [error:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0
                            [pathName:SplFileInfo:private] => /tmp/phpzdaQgW
                            [fileName:SplFileInfo:private] => phpzdaQgW
                        )

                    [1] => Symfony\Component\HttpFoundation\File\UploadedFile Object
                        (
                            [test:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 
                            [originalName:Symfony\Component\HttpFoundation\File\UploadedFile:private] => FLB2.gif
                            [mimeType:Symfony\Component\HttpFoundation\File\UploadedFile:private] => image/gif
                            [size:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 5193
                            [error:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0
                            [pathName:SplFileInfo:private] => /tmp/phpNUXho7
                            [fileName:SplFileInfo:private] => phpNUXho7
                        )

                )

        )

)

请帮我弄清楚这个对象访问.另外，如果有人有更好的方法在 Symfony2 中上传文件.

Please help me figure out this object access. Also if someone has a better way to upload files in Symfony2.

推荐答案

要访问文件，您可以执行类似操作

To access the files, you do something like

// retrieves an instance of UploadedFile
$request->files->get('file');
