Angular Auth0 - 如果经过身份验证，则获取 email 声明

Question

I want to get email claim, if user is already logged in.

this.auth.idTokenClaims$.forEach(e => console.log(">>>>>>>>>>>>>"+e.email));

is printing email

I want to write something like this ( because e can be null)

if((this.auth.isAuthenticated$ | async) === false){
      this.auth.idTokenClaims$.forEach(e => {
      this.cService.dash(e.email).subscribe(
        data => { this.yeah = data},
        err => console.error(err),
        () => console.log('Main Content ')

      )}
      );
   } else {

    this.cService.dash(null).subscribe(
      data => { this.yeah = data},
      err => console.error(err),
      () => console.log('Main Content from else '));
   }

Problem: if((this.auth.isAuthenticated$ | async) === false){

It says always evaluates to false, because

This condition will always return 'false' since the types 'number' and 'boolean' have no overlap.ts(2367)

or

The left-hand side of an arithmetic operation must be of type 'any', 'number', 'bigint' or an enum type.ts(2362)

something on these lines

Please can anyone help me resolve this

Answer 1

if isAuthenticated$ is an Observable or any kind of Subject I would try to structure the 2 streams into a pipe and do something like

this.auth.isAuthenticated$.pipe(
  skipWhile( isAuthenticated => isAuthenticated),
  switchMap( () => this.auth.idTokenClaims$ ),
  ...
).subscribe()

this.auth.isAuthenticated$.pipe(
  skipWhile( isAuthenticated => !isAuthenticated),
  switchMap( () => this.cService.dash(null) ),
  ...
).subscribe()

my main point here is that if you could give the types of each of the problematic variables, also $ sign at the end mostly stands for a Subject or Observable so I don't really understand what forEach has to do without subscription
