Angular 可观察和订阅

Question

i have one observable function in my service which i have subscribe but i am getting [object Object] instead of token value

service code:

get bearerToken(): Observable<string | null> {
  return this.store.select(AuthStatusState.getToken).pipe(
       map((token) => {
         if (token) {
           return token;
         } else {
           return null;
         }
       }),
       take(1)
     );
   }

code to which i have subscribed.

const authToken = this.authService.bearerToken.subscribe();
console.log(authToken);

i want token to be saved in const instead of object

Answer 1

Like this authToken is a subscription.

const authToken = this.authService.bearerToken.subscribe();

Like this authToken will be the value emitted by bearerToken .

let authToken;
this.authService.bearerToken.subscribe( data => authToken = data);
console.log(authToken);
