这是我尝试过的：

  $form = $this->createFormBuilder(null, ['method' => 'POST', 'csrf_protection' => false])
            ->add('file', FileType::class, [
                'required' => true,
                'constraints' => [
                    new File([
                        'mimeTypes' => [
                            'application/pdf',
                            'application/msword',
                            'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
                            'application/vnd.ms-excel',
                            'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
                            'image/gif',
                            'image/png',
                            'image/jpeg',
                            'application/vnd.oasis.opendocument.text',
                            'application/vnd.oasis.opendocument.spreadsheet'
                        ]
                    ]),
                    new Count(['min' => 1, 'max' => 1])
                ]
            ])
            //->add('submit', SubmitType::class)
            ->getForm();





        $form->handleRequest($request);
//        $form->submit($request->request->all(), false);
        $form->submit($request->files->get($form->getName()));

//        $this->


//        if ($form->isValid()) {
        if (/*$form->isSubmitted() &&*/ $form->isValid()) {

句柄请求未提交表单。如果我在句柄请求后调用Submit，它仍然无法验证。

我什至尝试

 /** @var UploadedFile $f */
            $f = $request->files->get('file');



            $violations = $this->container->get('validator')->validate($f, [
                new File([
                    'mimeTypes' => [
                        'application/pdf',
                        'application/msword',
                        'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
                        'application/vnd.ms-excel',
                        'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
                        'image/gif',
                        'image/png',
                        'image/jpeg',
                        'application/vnd.oasis.opendocument.text',
                        'application/vnd.oasis.opendocument.spreadsheet'
                    ]
                ]),
                new Count(['min' => 1, 'max' => 1])
            ]);

但是验证给出了错误：

给出了“数组或\​​ Countable”类型的预期参数，“ Symfony \ Component \ HttpFoundation \ File \ UploadedFile”。

我看到这与文档示例中的内容不同，但是如果可能的话，我不希望重构太多。这应该是简单的解决方法，但我花了几个小时却找不到。

$violations = $this->container->get('validator')->validate($f, [
                new File([
                    'mimeTypes' => [
                        'application/pdf',
                        'application/msword',
                        'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
                        'application/vnd.ms-excel',
                        'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
                        'image/gif',
                        'image/png',
                        'image/jpeg',
                        'application/vnd.oasis.opendocument.text',
                        'application/vnd.oasis.opendocument.spreadsheet'
                    ]
                ]),
                //new Count(['min' => 1, 'max' => 1])
            ]);

问题是新的伯爵。不需要，因为对于validate方法，如果我们上传多个文件，则$ f将是数组，并且会有异常，因此用户将无法上传多个文件。
