Question

Laravel TokenMismatchExpection when publishing inside iframe

I have a page working on http://some.example.com/myiframes/default.aspx. There is an iframe on this page. The iframe / source contains the base Laravel 5.2 application.

My url of the Laravel page, which is the source of the iframe, is https://laravel.example.com .

https://laravel.example.com has a form with a submit button. When use clicks it, he / she performs another route in the same domain, i.e. https://laravel.example.com/disply/survey

But every time I submit the form, I get the following exception

TokenMismatchException in VerifyCsrfToken.php line 67:

To make sure I understand, on the page, http://some.example.com/myiframes/default.aspxmy code looks something like this:

in my laravel application which is on https://laravel.example.com, here is my form

    <form method="POST" action="https://laravel.example.com/disply/survey" accept-charset="UTF-8" class="form">
