Angular 7/8 - How to get url parameters in app component

I have Single sign on in place but for testing I want to read the values from the url localhost:4200/?id=test&name=testing&email=testing@test.com and pass them to an API in app component.

there will be a flag on which basis I will reading from url instead of using single sign on function

if (url_enabled == true) {
    getParamsFromUrl()
 } else {
   singleSignOn()
 }

I tried ActivatedRoute but it doesn't seem to be working.

I have tried queryParams, params, url, queryParamsMap but none of these seems to be working. all I get is empty value.

inside app component

app.component.ts

 getParamsFromUrl() {
    this._router.events.subscribe((e) => {
      if (e instanceof NavigationEnd) {
        console.log(e.url)
      }
    })
  }

 this.route.queryParams.subscribe(params => {
      console.log(params);
    })

app.component.html

<router-outlet></router-outlet>

app-routing.module.ts

const routes: Routes = [
  {path:'*/:id', component: AppComponent},
];

I have tried whatever I could found on stackoverflow or other blogs. Can somebody point out what am I missing here?

For this route: You can try this way:

const routes: Routes = [
   {path:'*/:id', component: AppComponent},
];   

In AppComponent .ts file:

    constructor(
      private activatedRoute: ActivatedRoute,
    ) { }




    ngOnInit() {
      this.activatedRoute.params.subscribe(params => {
          const id = params['id'];
          console.log('Url Id: ',id);
    }

    OR

    ngOnInit() {
      this.activatedRoute.queryParams.subscribe(params => {
          const id = +params.id;
          if (id && id > 0) {
           console.log(id);
          }
      });
    }

first of all there is an url with queryParams like yours :

localhost:4200/?id=test&name=testing&email=testing@test.com

in this way tou get to the queryparams with ActivatedRoute object lik :

 this.name = this.activatedRoute.snapshot.queryParamMap.get('name'); // this.name = 'testing'

Or :

 this.activatedRoute.queryParams.subscribe(params => {
       this.name= params['name'];
     });

and the other way is

localhost:4200/test/testing/testing@test.com

you use for sync retrieval (one time) :

this.name = this.activatedRoute.snapshot.ParamMap.get('name');

Angular comes us with the ActivatedRoute object. We can access the URL parameter value in same way its done above with little difference. Data in this type can be accessed with two different ways. One is through route.snapshot.paramMap and the other is through route.paramMap.subscribe. The main difference between the two is that the subscription will continue to update as the parameter changes for that specific route.

ngOnInit() {
    this.route.paramMap.subscribe(params => {
        this.userType = params.get("userType")
    })
}
