Angular universal express server shows function url instead of entry url

Question

Help i need to get my custom domain to fetch store config but when I try to use the url on the server side is showing me the cloud function url, not the url that the user typed in. example: my user types in the browser https://test-url.mybuss.co/ Hosting redirects to functions (i.e. https://us-east1-blablabla.com/) functions renders my html this includes making some http calls to my API BUT I have two ways to recognize which company is trying to check my store

First one query params https://test-url.mybuss.co/myStore I sent myStore as a query parameter and success second case https://test-url.mybuss.co/ I sent the host url as a parameter and success BUT whenever I'm on server side instead of sending this URL(https://test-url.mybuss.co/) the express server catches the cloud function url. Any ideas?

I've tried every host parameter

console.log(req.headers.host);

console.log(req.hostname);

console.log(req.host); // even this deprecated one

console.log(req.subdomains)

and they all give me the same result https://us-east1-blablabla.com/

Tried using platformLocation and also tried this solution right here

req.get('host')

get server url

Answer 1

So the solution to my answer was using the parameter x-fowarded-Host Which I obtained by req.get('x-forwarded-Host') And transfered through providers

 res.render(indexHtml, {
      req, providers: [
        { provide: APP_BASE_HREF, useValue: req.baseUrl },
        { provide: 'ORIGIN_URL', useValue: req.get('x-forwarded-Host') },
      ]
    });

I also had to include these lines app.server.module.ts

@NgModule({
  imports: [
    AppModule,
    ServerModule,
    ServerTransferStateModule,
  ],

app.module.ts

  imports: [
    BrowserTransferStateModule
],

to retrieve the data in my resolver I had to include this variable in my constructor

@Optional() @Inject('ORIGIN_URL') public urlOrigin: string
