php 配置跨域（laravel 版）

在中间件中配置如下：

public function handle( $req , Closure $next) {

$res = $next($req) ;

$origin = $req->server('HTTP_ORIGIN');
$res->header('Access-Control-Allow-Origin', $origin);
$res->header('Access-Control-Allow-Headers', 'Origin, Content-Type, Cookie, X-CSRF-TOKEN, Accept, Authorization, X-XSRF-TOKEN, X-Request-With');
$res->header('Access-Control-Expose-Headers', 'Authorization, authenticated');
$res->header('Access-Control-Allow-Methods', 'GET, POST, PATCH, PUT, OPTIONS');
$res->header('Access-Control-Allow-Credentials', 'true');


return $res ;


}
