Laravel CSRF令牌到期

Question

I am new to Laravel 5.4 and have just created a login form. The thing which I have noticed is, if I left the login for some 2 hrs and returned back, my csrf token would get expire. Is it possible to show a javascript alert box that the session has expired and after clicking the OK button it will take me to the login page again?

Answer 1

You can do something like In your view. using the auth helper function.

@if (! auth()->check())
      <script type="text/javascript">
                alert('session expired!!')
      </script>
@endif

Edit:

Okay the above function runs only once when the page is loaded and does not meet OPs requirements so to solve this we can try and directly catch the token-mismatch exception in the back-end side.

So In method render() of /app/Exceptions/Handler.php you could try something like:

if ( $e instanceof \Illuminate\Session\TokenMismatchException ) {
    return redirect()->route('login');
}
