Angular5 服务器端渲染（（未知 url）的 Http 失败响应：0 未知错误）。

我相信上述错误与 CORS 有关。但是没有 SSR 的 angular5 CORS 工作正常。

当我将 Api 更改为子域时，会特别发生这种情况

Laravel API：http://api.localhost:80

节点快递：http://localhost:3000

下面是我为 Laravel PHP api 添加的标题。

        header('Access-Control-Allow-Origin: http://localhost:3000');
        header('Access-Control-Allow-Credentials: true');
        header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE');
        header('Access-Control-Allow-Headers: Origin, Content-Type,Accept, X-Auth-Token ,App-Auth,X-XSRF-TOKEN,Authorization');
        header('Access-Control-Max-Age: 86400');

使用 Node 与 Laravel PHP 通信时，出现以下错误
