yii2 ajax 跨域

header("Access-Control-Allow-Origin: *");
header('Access-Control-Allow-Headers:Authorization');
header("Access-Control-Allow-Methods: GET, POST, DELETE");
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Headers: Content-Type, X-Requested-With, Cache-Control,Authorization");

其他框架第一行就可以,放框架入口文件index.php文件即可,restful风格的接口加后面两个配置即可
