在Laravel中上传某些文件类型时出现问题
在我的应用程序中，我有一个TemplateController，其中包含批量上传方法。它运作良好，但是只要我尝试上传.eps文件，Laravel就会返回验证错误。
files.0必须是以下类型的文件：jpg，jpeg，png，gif，ai，eps，mp3， ogg，mpga，mp4，mpeg，doc，docx，dotx，pdf，odt，xls，xlsm，xlsx，ppt， pptx，vsd。
我的问题是，我可以在验证程序期望的文件扩展名列表中看到eps。
这里是TemplateController

}
我还对单个eps文件执行了$extension变量的转储和处理，并且确实返回了eps。
为了进入此示例，我必须删除验证：
$this->validate($request, [
'files.*' => 'required|file|mimes:' . $all_ext . '|max:50000'
]);
精简代码段
foreach ($request->file('files') as $file) {
// Get the meta data for each file
$name = $file->getClientOriginalName();
$extension = strtolower($file->getClientOriginalExtension());
$type = $this->getType($extension);
$size = $file->getSize();
dd($extension);
}
当我尝试上传相同的文件时，浏览器输出如下：
“ eps”
无论如何，脚本在获取扩展名时就死了，这显然是eps
eps文件有什么不同吗？还是我很密集？
在允许的扩展名列表中，我确实测试了所有其他扩展名，这些扩展名如下：
/**
* Set allowed extensions for each file category
* This can be appended to as necessary as it's somewhat restrictive
*/
private $image_ext = [
'jpg', 'jpeg', 'png', 'gif',
'ai', 'eps'
];
private $audio_ext = [
'mp3', 'ogg', 'mpga'
];
private $video_ext = [
'mp4', 'mpeg'
];
private $document_ext = [
'doc', 'docx', 'dotx', 'pdf', 'odt',
'xls', 'xlsm', 'xlsx',
'ppt', 'pptx',
'vsd'
];
请澄清一下，files是一个已上传文件的数组，其HTML是：
<input type='file' name='files[]' multiple required />
