普通响应跨域，在中间件里是这么设置，设置的是header()方法：

$response->header('Access-Control-Allow-Origin', '*');
$response->header('Access-Control-Allow-Credentials', 'true');
$response->header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Control-Type, Content-Type, token, Accept, x-access-sign, x-access-time, Content-Disposition");
$response->header("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");

而遇到导出表格文件流，这种文件响应，需要这么设置，设置的是headers属性：

$response->headers->set('Access-Control-Allow-Origin', '*');
$response->headers->set('Access-Control-Allow-Credentials', 'true');
$response->headers->set("Access-Control-Allow-Headers", "Origin, X-Requested-With, Control-Type, Content-Type, token, Accept, x-access-sign, x-access-time, Content-Disposition");
$response->headers->set("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");

完整示例如下：

if (!$response instanceof BinaryFileResponse) {
    //普通响应 使使用header()方法来设置CORS头
    $response->header('Access-Control-Allow-Origin', '*');
    $response->header('Access-Control-Allow-Credentials', 'true');
    $response->header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Control-Type, Content-Type, token, Accept, x-access-sign, x-access-time, Content-Disposition");
    $response->header("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");
}else{
    //文件响应 使用headers属性来设置CORS头
    $response->headers->set('Access-Control-Allow-Origin', '*');
    $response->headers->set('Access-Control-Allow-Credentials', 'true');
    $response->headers->set("Access-Control-Allow-Headers", "Origin, X-Requested-With, Control-Type, Content-Type, token, Accept, x-access-sign, x-access-time, Content-Disposition");
    $response->headers->set("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");
}
if ($request->isMethod('OPTIONS')) return $response; //OPTIONS不记录日志
