How to use CSRF protection in Laravel
Laravel enables CSRF protection by default, 1. Prevent cross-site request forgery by generating a unique token for each user session; 2. Automatically insert hidden token fields in the form using the @csrf directive; 3. AJAX requests need to obtain the token in the meta tag and set the X-CSRF-TOKEN request header; 4. Unprotected routes such as webhooks or APIs can be excluded in the $except array of VerifyCsrfToken middleware; 5. Common token errors are caused by the misconfiguration of missing tokens, expired, cached or subdomain names. Make sure to include the token correctly, avoid cached tokens and configure SESSION_DOMAIN, as long as the token is included in each state change request.
