request 註意事項 mod style nbsp method option nat agen
因為跨域請求會先發送一個OPTIONS請求,所以需要判斷下OPTIONS請求的就直接返回
if(strtoupper($_SERVER[‘REQUEST_METHOD‘])== ‘OPTIONS‘){ header("Access-Control-Allow-Origin:*"); header("Access-Control-Allow-Headers:content-type"); header("Access-Control-Request-Method:GET,POST"); exit; }
在返回json數據的時候需要在頭部加上
header(‘Access-Control-Allow-Origin: *‘); header(‘Access-Control-Allow-Methods: GET,POST‘); header(‘Access-Control-Allow-Headers: Destination, Content-Type, User-Agent, X-Requested-With, If-Modified-Since‘); header(‘Access-Control-Allow-Credentials: true‘);
