How to set up Cross-Origin Resource Sharing (CORS) using middleware in the Slim framework Cross-Origin Resource Sharing (CORS) is a mechanism that allows the server to set some additional information in the HTTP response header to tell the browser whether Allow cross-domain requests. In some projects with front-end and back-end separation, the CORS mechanism can be used to realize the front-end's cross-domain request for the back-end interface. When using the Slim framework to develop REST API, we can use middleware (Middleware)

PHP Framework Security Guide: How to Prevent CSRF Attacks? A Cross-Site Request Forgery (CSRF) attack is a type of network attack in which an attacker tricks a user into performing unintended actions within the victim's web application. How does CSRF work? CSRF attacks exploit the fact that most web applications allow requests to be sent between different pages within the same domain name. The attacker creates a malicious page that sends requests to the victim's application, triggering unauthorized actions. How to prevent CSRF attacks? 1. Use anti-CSRF tokens: Assign each user a unique token, store it in the session or cookie. Include a hidden field in your application for submitting that token
