如果发现任何无效Url,Angular 4+Universal重定向到404页面

export class NotFoundComponent implements OnInit {

  constructor(@Inject(PLATFORM_ID) private platformId: Object,
              @Optional() @Inject(RESPONSE) private response: Response) {
  }


  ngOnInit() {
    if (!isPlatformBrowser(this.platformId)) {
      this.response.status(404);
    }
  }

}

app.engine('html', (_, options, callback) => {
  renderModuleFactory(AppServerModuleNgFactory, {
    // Our index.html
    document: template,
    url: options.req.url,
    extraProviders: [
      // make req and response accessible when angular app runs on server
      <ValueProvider>{
        provide: REQUEST,
        useValue: options.req
      },
      <ValueProvider>{
        provide: RESPONSE,
        useValue: options.req.res,
      },
    ]
  }).then(html => {
    callback(null, html);
  });
})

由于我自己刚刚偶然发现这个问题,我在一篇博客文章中记录了我的过程。如果您需要更多指导,请查看:
