Symfony .edi、.seq和.xls的格式

我正在使用Symfony的表单生成器，我为表单创建的类如下所示：

use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\Validator\Constraints as Assert;

class Upload

{

    /**
     * @Assert\File(
     *     maxSize = "4000k",
     *     mimeTypes = {"text/plain", "text/xml", "application/xml", "text/csv", 
     *                  "application/EDI-consent", "application/EDIFACT", "application/EDI-X12"
     *                  "application/vnd.mseq", "application/json-seq", 
     *                  "application/vnd.sealed-xls", 
     *                  "application/pdf", "application/x-pdf",
     *                  "application/zip"},
     *     mimeTypesMessage = "Please upload a valid format file"
     *     )
     * @var file
     */
     protected $file;

     ...

我需要接受以下扩展： 'txt、dat、xml、csv、edi、seq、xls、pdf、zip'

这样够了吗？还有什么要补充的吗？我有什么问题吗

Symfony Docs建议从这里获得结果：

我认为它应该正常工作。也许您应该添加application/octet流和zz application/zz winassoc dat来匹配。和用不同的文件测试你的代码，看看它是否有效
