Many times we faced a Tokenmismatch error in laravel. This error occurs If you stay too long time on one form or if your system stays idle or if you are not active on your computer, and then again try to fill this form.

    At that time you may get a TokenMismatchException error because the CSRF token won’t be the same. recently many times we found this problem in logout time. So, In this example, we will see you how to avoid it.

    Normally, if you are not active for a long time in your system then you will get errors like the below screen print.

    To avoid the TokenMismatchException error, we may add exceptions for the URLs that we don’t want to have CSRF protection. There are special array for that in app/Http/Middleware/VerifyCsrfToken.php

class VerifyCsrfToken extends Middleware
{
    /**
     * The URIs that should be excluded from CSRF verification.
     *
     * @var array
     */
    protected $except = [
        //
    ];
}

    So what we need to do, is just add logout into this array.

protected $except = [
    '/logout'
];

    If you want to add more URLs then you can add them here.
