Handling expired token in Laravel

Question

What is the best way to handle expired tokens in laravel 5.

I mean I have a page and it has some links which perform ajax requests. They work fine when the page is

Answer 1

I combine 2 things for this case:

1. Increase session lifetime

//In config/session.php replace this:

'lifetime' => 120

//with:

'lifetime' => 360

^{Laravel 5 default lifetime is 120 (minutes), you can change it to whatever value you like, for example 360 (6 hours)}

2. Catch the exception and display an error message

//In app/Exceptions/Handler.php replace this:

public function render($request, Exception $e)
{
    if ($e instanceof ModelNotFoundException) {
        $e = new NotFoundHttpException($e->getMessage(), $e);
    }

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

//with:

public function render($request, Exception $e)
{
    if ($e instanceof ModelNotFoundException) {
        $e = new NotFoundHttpException($e->getMessage(), $e);
    }

    if ($e instanceof \Illuminate\Session\TokenMismatchException) {            
        return redirect('/')->withErrors(['token_error' => 'Sorry, your session seems to have expired. Please try again.']);
    }

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

^{So basicaly you redirect the user to the root "/" (you can change this to any path you want) with an error message and on that page you have to do this to display the error message:}

@if ($errors->has('token_error'))
    {{ $errors->first('token_error') }}
@endif
