CORS is a security mechanism enforced by web browsers to restrict cross-origin HTTP requests.

CORS is a mechanism implemented by browsers that block websites to request data from some other URL. When a browser makes a request, it adds an origin header to the request message. If it goes to the server of the exact origin, it is allowed by the browser; if it does not, the browser blocks it. gets error like Cross-Origin Request Blocked
