我在上传图片时出现 HTTP ERROR(500) 错误，
但在CONSOLE时也查看不到有什麽错误提示。
网上查案时说可能权限错误 我也改了 还是一样...
求求帮忙，谢谢><

Controller

public function upload()
{
    $file = Input::file('Filedata');
    if($file -> isValid()){
        $entension = $file -> getClientOriginalExtension(); //上传文件的后缀.
        $newName = date('YmdHis').mt_rand(100,999).'.'.$entension;
        $path = $file -> move(base_path().'/uploads',$newName);
        $filepath = 'uploads/'.$newName;
        return $filepath;
    }
