Laravel上传文件Mime类型错误

问题描述 投票:2回答:4

我在以下代码中出现一些错误,我进行了很多搜索,但没有得到解决方案。我想上传file.xls,对吗?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>

我的控制器功能

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.

您应该将此attr添加到表单元素:

enctype="multipart/form-data"

我也通过laravel的验证器进行mime类型验证时遇到了问题,所以我最终使用类似的方法手动完成了该任务

$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

Laravel 6:

我尝试上传扩展名为webm的视频。

[dd($request)返回mimetype:video/webm,分别,我尝试在规则中使用它。但是我得到了mimetype错误错误。

我检查了另一个$request->file('video')->getMimeType()并得到了video/x-matroska。而且我使用了规则mimetypes:video/x-matroska。它对我有用。

我尝试过,找到了解决方案。

// validating each file.
          $rules = array('file' => 'required'); 
          $validator = Validator::make(
                [
                    'file' => $file,
                    'extension'  => \Str::lower($file->getClientOriginalExtension()),
                ],
                [
                    'file' => 'required|max:100000',
                    'extension'  => 'required|in:jpg,jpeg,bmp,png,doc,docx,zip,rar,pdf,rtf,xlsx,xls,txt'
                ]
            );

          if($validator->passes())
          {

            // path is root/uploads
            $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);

            if( $upload_success) 
            {
               return Response::json('success', 200);
            } 
            else 
            {
               $errors .= json('error', 400);
            }

          } 
          else 
          {
            // redirect back with errors.
            return Redirect::back()->withErrors($validator);
          }
