I cant get the values of a subscribe in angular 9

Question

I want to get the status code and body of a subscription.

WOWEE I cant. Well I can but utterly useless since I cant return.

@Injectable()
export class ApiService {

constructor(private _http: HttpClient, 
              private _authHttp: HttpClient,
              public jwtHelper: JwtHelperService,
              private loggedinService: LoggedinService){

  }

  status_code:number

 def test(){
    var result_ = this._http.get(this.getEndpointUrl(endpoint), {headers: new HttpHeaders({ 'Content-Type':  'application/json','Authorization': localStorage.getItem('id_token') }),observe: 'response'});

    result_.subscribe(resp=>{
      this.status_code = resp.status
      console.log(resp.status). //works
    })

    let wtf = result_.toPromise().then(resp => console.log('toPromise', this.status_code = resp.status));

   return this.status_code.  //null

 }

How do I wait to return? Clearly returning before the subscribe finishes

You should really read the docs on this more thoroughly https://angular.io/guide/http — Liam, Mar 26 '20 at 08:56

Subscription is done asynchronously that's why when you return value of this.status_code synchronously it's not set.

What you can do is returning

this._http.get(this.getEndpointUrl(endpoint), {headers: new HttpHeaders({ 'Content-Type':  'application/json','Authorization': localStorage.getItem('id_token') }),observe: 'response'})

in your method and subscribe to that it in a place where the method is invoked.
