Laravel 文件未上传

      $.ajax({

        url: 'file.remove',
        data: { "_token": "{{ csrf_token() }}", name: name},
        success: function (data){
            console.log("File has been successfully removed!!");
        },
        error: function(e) {
            console.log(e);
        }});
        var fileRef;
        return (fileRef = file.previewElement) != null ?
        fileRef.parentNode.removeChild(file.previewElement) : void 0;
    },
    success: function (file, response) {
      console.log(response);
    },
  }
</script>

// **my web.php**


Route::get('upload',function(){
    return view('upload');
});
Route::post('upload/classification', [imageClassificationController::class, 'uploadDataset']);

<?php

// my imageClassificationController.php

namespace App\Http\Controllers;
use App\Models\imageClassificationModel;
use Illuminate\Http\Request;
use App\Models\fileTransferModel;
use Auth;
config('projectConfigs.pathConfigs');
class imageClassificationController extends Controller
{
    
    public function uploadDataset()
    {
        try{
        
        $file = request()->file();
        //echo 'File Name: '.$file->getClientOriginalName();
        //return __DIR__;
        //$fileName= $file->getClientOriginalName();
        //return $file;
        

$file->move(__USERFOLDERS__.DIRECTORY_SEPARATOR.Auth::user('foldername').DIRECTORY_SEPARATOR.'image-classification'.DIRECTORY_SEPARATOR.'datasets',$file);
        return $file->getClientOriginalName();
    }
        catch(Exception $e){
            return 'test'.$e;
            
        }
        
    }
    
    

}

这些代码return 500 内部服务器错误。但是如果我 return $file，它 returns javascript 文件对象。我不知道为什么我不能保存上传的文件。还有 getClientOriginalName returns 500 内部服务器错误。最后，try-catch 也 returns 500 内部服务器错误。

感谢您的帮助...

您必须将输入名称添加到请求文件功能，并使用 Laravel 文件移动功能：

public function uploadDataset()
{
    try{
    
    $file = request()->file('file'); // the input name attribute
    

    $file->move(__USERFOLDERS__.DIRECTORY_SEPARATOR.Auth::user('foldername').DIRECTORY_SEPARATOR.'image-classification'.DIRECTORY_SEPARATOR.'datasets'.DIRECTORY_SEPARATOR, $file->getClientOriginalName());
    return $file->getClientOriginalName();
    }
    catch(Exception $e){
        return 'test'.$e;
        
    }
    
}
