php - Laravel 上传文件 Mime 类型错误

Question

我在下面的代码中遇到了一些错误，我搜索了很多，但没有得到解决方案。我想上传file.xls，我错了吗？谢谢

我的 HTML 表单:

 <form class="form-horizontal" role="form" method="post" action="{{ URL::to('doc/test') }}" enctype="multipart/form-data">
  <input style='width:400px;' type='file' id='files'  name='files[]' class="form-control" multiple='multiple'>
  <button type="submit" class="btn btn-primary">Save</button>
</form>

我的 Controller 功能

public function uploadDocs()
        {
            $files = Input::file('files');
            $errors = "";
            foreach($files as $file) 
            {
              $rules = array('file' => 'mimes:png,gif,jpeg,pdf,doc,docx,xls,xlsx,max:1000000'); //'required|mimes:png,gif,jpeg,txt,pdf,doc'
              $validator = Validator::make(array('file'=> $file), $rules);
              if($validator->passes())
              {
                $destinationPath = 'documents';
                $filename = $file->getClientOriginalName();
                $temp = explode(".", $filename);
                $extension = end($temp);
                $filename = $temp[0].'_'.date('Y-m-d H:i:s').$extension;
                $upload_success = $file->move($destinationPath, $filename);
              } 
              else 
              {
                return Redirect::back()->withErrors($validator);
              }
            }

        }

错误:

The file must be a file of type: png, gif, jpeg, pdf, doc, docx, xls, xlsx, max:1000000.

我在通过 Laravel 验证器进行 mime 类型验证时也遇到了问题，所以我最终用这样的方法手动完成了

$supported_mime_types = array('application/vnd.ms-excel');
$file = Input::file('file');
$mime = $file->getMimeType();

if (!in_array($mime, $supported_mime_types)) {
  // mime type not validated
}

您仍然可以保留文件大小的规则
