php cors
/** * An example CORS-compliant method. It will allow any GET, POST, or OPTIONS requests from any * origin. * * In a production environment, you probably want to be more restrictive, but this gives you * the general idea of what is involved. For the nitty-gritty low-down, read: * * - https://developer.mozilla.org/en/HTTP_access_control * - https://fetch.spec.whatwg.org/#http-cors-protocol * */ function cors() { // Allow from any origin if (isset($_SERVER['HTTP_ORIGIN'])) { // Decide if the origin in $_SERVER['HTTP_ORIGIN'] is one // you want to allow, and if so: header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}"); header('Access-Control-Allow-Credentials: true'); header('Access-Control-Max-Age: 86400'); // cache for 1 day } // Access-Control headers are received during OPTIONS requests if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') { if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD'])) // may also be using PUT, PATCH, HEAD etc header("Access-Control-Allow-Methods: GET, POST, OPTIONS"); if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS'])) header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}"); exit(0); } echo "You have CORS!"; }
