php - how to show 500 internal Server error page in laravel 5.2?

Solution:

In yourresources/views/errors folder create a file named500.blade.php.

Laravel makes it easy to display custom error pages for various HTTP status codes. For example, if you wish to customize the error page for 500 HTTP status codes, create aresources/views/errors/500.blade.php. This file will be served on all 500 errors generated by your application.

The problem is that Laravel will only do this automatic rendering of error pages for exceptions that are instances ofHttpException. Unfortunately when your server throws an error (method does not exist, variable undefined, etc) it actually throws aFatalErrorException. As such, it is uncaught, and trickles down to theSymfonyDisplayer() which either gives you the trace (debug true) or ugly one-liner 'Whoops, looks like something went wrong' (debug false).

To solve this you have add this to yourrender method toapp/Exceptions/Handler

# /app/Exceptions/Handler.php

# use Symfony\Component\Debug\Exception\FlattenException;

# public function render($request, Exception $e)

$exception = FlattenException::create($e);
$statusCode = $exception->getStatusCode($exception);

if ($statusCode === 404 or $statusCode === 500) {
    return response()->view('errors.' . $statusCode, [], $statusCode);
}
Copy code

Solution:

My solution is simple, just replace your render() method in Exceptions\Handler.php file with:

/**
 * Render an exception into an HTTP response.
 *
 * @param \Illuminate\Http\Request $request
 * @param \Exception               $exception
 *
 * @return \Illuminate\Http\Response
 */
public function render($request, Exception $exception)
{
    if ($request->expectsJson()) {
        return $this->renderJson($request, $exception);
    }

    if ($this->shouldReport($exception) && app()->environment('production')) {
        $exception = new HttpException(500, $exception->getMessage(), $exception);
    }

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

It will show 500 page if app in production environment. You will need to have 500.blade.php view in your resources/views/errors folder.

Solution:

    // app/Exceptions/Handler.php

    protected function prepareResponse($request, Exception $e)
    {
        if($this->isHttpException($e) === false && config('app.debug') === false)     {
            $e = new HttpException(500);
        }

        return parent::prepareResponse($request, $e);
    }

Like @Amit said

The problem is that Laravel will only do this automatic rendering of error pages for exceptions that are instances of HttpException.

So my solution is to replace whatever exception that is not HttpException by a HttpException.

Solution:

in app\Exceptions\Handler create the following method:

protected function convertExceptionToResponse(Exception $e)
{
        $e = FlattenException::create($e);
        return response()->view('errors.500', ['exception' => $e], $e->getStatusCode(), $e->getHeaders());
}
Copy code

it will override the one in the parent class (Illuminate\Foundation\Exceptions\Handler) that displays the whoops page.

Solution:

In Laravel 5.4, you could overrideprepareException function in yourapp\Exception\Handler.php:

/**
 * @inheridoc
 */
protected function prepareException(Exception $e)
{
    $exception = parent::prepareException($e);

    if(!config('app.debug')) {
        if(!$exception instanceof HttpException && $this->shouldReport($exception)) {
            $exception = new HttpException(500);
        }
    }

    return $exception;
}
