如何通过Controller上传图片？

Question

我正在尝试使我的Laravel Voyager应用程序通过Controller而不是根据filesystems.php的设置将帖子的新闻图像上传到另一个文件夹中

之所以这样做，是因为我希望张贴的文件结构井井有条，因此图像将放入名为“ 2019”的文件夹中。

反正有实现这一目标的方法吗？

NewsController.php

public function store(Request $request)
{
    $slug = $this->getSlug($request);

    $dataType = Voyager::model('DataType')->where('slug', '=', $slug)->first();

    // Check permission
    $this->authorize('add', app($dataType->model_name));

    // Validate fields with ajax
    $val = $this->validateBread($request->all(), $dataType->addRows);

    if ($val->fails()) {
        return response()->json(['errors' => $val->messages()]);
    }

    if (!$request->has('_validate')) {
        $data = $this->insertUpdateData($request, $slug, $dataType->addRows, new $dataType->model_name());

        event(new BreadDataAdded($dataType, $data));

        if ($request->ajax()) {
            return response()->json(['success' => true, 'data' => $data]);
        }

        return redirect()
            ->route("voyager.{$dataType->slug}.index")
            ->with([
                    'message'    => __('voyager::generic.successfully_added_new')." {$dataType->display_name_singular}",
                    'alert-type' => 'success',
                ]);
    }
}
