Angular 5 POST requests for my page

I'm receiving POST request to my Angular page, which might look like:

https://www.myangularsite.com/login 
"POST /login HTTP/1.1
token: randomstring"

My app module looks like

export const routes: Routes = [
  { path: 'login', component: LoginComponent },
  { path: '', redirectTo: 'login', pathMatch: 'full' },
  { path: '**', redirectTo: 'login', pathMatch: 'full' }
];

@NgModule({
  declarations: [
    LoginComponent,
    AppComponent
  ],
  imports: [
    BrowserModule,
    HttpClientModule,
    RouterModule.forRoot(routes, {errorHandler: errorLogger } )
  ],
  bootstrap: [ AppComponent ]
})
export class AppModule { }

My problem is that Angular application doesn't accept POST method requests, only GET. Page displays

Cannot POST /login

I'm running web server through ng serve. Is it possible to set it up to listen to POST requests? I can't change received request to GET.

Even though it is POST request, it is not a backend call. It is called after authorization (similar from oauth), therefore it should display page after login.

You can use node.js Express as your CLI server. Please see the post at  http://tattoocoder.com/angular2-giving-your-cli-server/  on how to do that.

Then in your express server.js, you can listen the post request for login:

var express        =         require("express");
var bodyParser     =         require("body-parser");
var app            =         express();

app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

app.get('/',function(req,res){
  res.sendfile("index.html");
});
app.post('/login',function(req,res){
  var user_name=req.body.user;
  var password=req.body.password;
  console.log("User name = "+user_name+", password is "+password);
  res.end("yes");
});
app.listen(3000,function(){
  console.log("Started on PORT 3000");
})
