如何使用ajax在LARAVEL中获取新的CSRF令牌

Question

I have created a form which is having a lot of fields and user can create an unlimited field in it. If a user spends more time on it CSRF token get expires and when he clicks on the submit LARAVEL return the error CSRF token mismatch. So how can I get new CSRF token by using ajax call so I can update the CSRF on a regular time of interval? I can not refresh or reload the form.

Just add this to your script

<script type="text/javascript">
            $.ajaxSetup({
                headers: {
                    'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
                }
            });
</script>

And make sure you have added token to your meta tag like below.

<meta name="_token" content="{!! csrf_token() !!}" />

I hope this will work for you.
