服務(wù)端用法
php代碼如下
// Make sure file is not cached (as it happens for example on iOS devices)
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
// Support CORS
// header("Access-Control-Allow-Origin: *");
// other CORS headers if any...
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
exit; // finish preflight CORS requests here
}
