angular - Angular Universal - 多个 NetworkError

Question

当我使用 ng add @nguniversal/express-engine 实现角度通用时，我看到了大约 20 个错误...

ERROR NetworkError

我有相当大的应用程序，因此很难调试。在网络应用程序上，几乎一切都很好，只是我在刷新时遇到问题，如果它不是基本 url，它只是继续挂起......我测试了 GUI，每个功能都有效，每个 api 请求都有效，但为什么我会收到这些错误？

我有 socket.io-client 我在其中添加了平台检查...

    if (this.isBrowser) {
      this.socket = io('https://localhost:4200', {
        transports: ['websocket'],
      });
    }

对于身份验证，我使用的是 httponly 安全 cookie，并且我有拦截器，它在每个请求上添加 withCredentials，我认为这可能是一个问题，但是当我删除时，一切都保持不变..

   intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        const authReq = request.clone({
          withCredentials: true
        });
        return next.handle(authReq);
      ;
  }

我正在使用 api 的绝对路径，这是我的服务示例..

  url = environment.url;

   getMyReviews(): Observable<any> {
    return this.http.get<any>(this.url + '/users/getMyReviews');
  }

而且我正在使用ngrx，我真的不知道是什么导致了这些问题。
