Question

我已经创建了文件上传方法，并且文件扩展名为jpg, png等的文件上传成功。但是，当我上传一个zip文件时，它说我“ Undefined variable: e”。为了找到答案，我在相应方法的开头做了dd()，但它仍然显示上述错误。我的路线如下：

Route::post('media/savedata/{id?}/{page?}', 'Administrator\MedialibraryController@savedata');

方法如下：

public function savedata($id, $page, Request $request) {
 ...
}

“网络”标签的内容如下：

Request URL: http://localhost/stmd/administrator/media/savedata/0/1
Request Method: POST
Status Code: 500 Internal Server Error
Remote Address: [::1]:80
Referrer Policy: no-referrer-when-downgrade

Content-Disposition: form-data; name="fileName"; filename="gradle-3.5-bin.zip"
Content-Type: application/zip

我的意图是：如果上传zip文件，它将重定向到另一个页面，但是我无法执行此操作，因为即使dd()也无法正常工作。

更新：

下面是Laravel日志：

我的Handler.php内容如下：

public function render($request, Exception $exception)
    {
        if($this->isHttpException($exception)){
            $logFile = 'laravel.log';

            Log::useDailyFiles(storage_path().'/logs/'.$logFile);
            //echo Route::getCurrentRoute()->getAction();



            //echo $exception->getStatusCode();exit;
            switch ($exception->getStatusCode()) {

                case 404:
                    Log::info('Unable to find page.');
                    return response()->view('errors.404',[],404);

                    break;

                case 500:

                    Log::error('In Server is really going wrong.');
                    return response()->view('errors.500',[],500);

                    break;
                 default:
                    return $this->renderHttpException($e);
                break;

            }

        }
        return parent::render($request, $exception);
    }
}

Answer 1

更改

return $this->renderHttpException($e);

到

return $this->renderHttpException($exception);

在

app/Exceptions/Handler.php

Answer 2

您可以在app/Exceptions/Handler.php.的异常处理程序中处理FileException异常，更新render方法以添加所需的代码。例如，如果您想返回验证异常，则需要在FileHandler异常的异常处理程序中处理验证。

public function render($request, Exception $exception)
{
    if ($exception instanceof \Symfony\Component\HttpFoundation\File\Exception\FileException) {
        // create a validator and validate to throw a new ValidationException
        return Validator::make($request->all(), [
            'your_file_input' => 'required|file|size:5000',
        ])->validate();
    }

    return parent::render($request, $exception);
}

这是未经测试的，但应该可以让您大致了解。

Answer 3

if ($exception instanceof \Illuminate\Http\Exceptions\PostTooLargeException)
            return \Redirect::to('administrator/media')->with('errorMessage', 'Please upload an image.');
