如何在laravel中使用特殊消息管理特殊错误

Question

I'm using laravel 5.4. and I need handle some error. imagine user logged in and opened two windows (his profile). When user click on logout in a window, we have still logout button in another window, and by clicking on that, laravel will show csrf_token error page.

My logout in not ajax and its with submitting a form to /logout how can I handle this error with special message or redirect to home without error from logout controller? (not all of csrf_token errors, just from that controller).

logout form :

i will submit this form by clicking on logout button using jquery:

<form id="logout-form" action="/logout" method="POST" style="display: none;">
    <input type="hidden" name="_token" :value="token">
</form>

And the logout method in controller :

public function logout(Request $request)
{
    $this->guard()->logout();
    $request->session()->flush();
    $request->session()->regenerate();
    return redirect('/');
}

Answer 1

in App\Exceptions\Handler.php Return the user to the form with a new valid CSRF token, so the page will refreshed and logout button will not exist.

public function render($request, Exception $exception)
{ 
   if($exception instanceof TokenMismatchException)
   { 
      return redirect()
               ->back()
               ->with('your msg');
   }
   return parent::render($request, $exception); 
}

this looking like, page was refreshed.

Don't Replace POST with Get. It will not Safe And Standard.
