Hi, how can i return the result of this http get?


getChatId(emailTo) {

    var email = emailTo
    this.storage.get('token').then((val) => {
      const httpOptions = {
        headers: new HttpHeaders({
          'Accept': 'application/json',
          'Content-Type': 'application/json',
          'Token': val
        })
      };

      this.httpClient.get("https://sxxxxxx=" + email, httpOptions)
        .subscribe(data => {
          console.log(data['_body']);
        }, error => {
          console.log(error);
        });
    });

  }

Your question looks confusing.
If possible please format it correctly and explain what you want to achieve and what are you getting?
Thanks

I think it should like this

token:string=’’;
result=any;

getChatId(emailTo) {
this.storage.get('token’).pipe(
switchMap(output=> {
 this.token = output.property;
 const httpOptions = {
        headers: new HttpHeaders({
          'Accept': 'application/json',
          'Content-Type': 'application/json',
          'Token': this.token
        })
      };
  this.httpClient.get("https://sxxxxxx=" + email, httpOptions)
        .subscribe(data => {
          console.log(data['_body']);
         this.result=JSON.stringify(data)

        //use this result 
        }, error => {
          console.log(error);
        });
    });
   });
    });
  }

Just check braces properly closing and opening.
hope it helps

You may get error while getting token from nativestorage.
It returns Promise.

create one func which return observable from promise

getToken (): Observable<any> {
    return from(this.storage.get('token'));
}

Then use this getToken() in above code .

getToken().pipe(

rest of the code )
