Angular 4, convert http response observable to object observable

Question

I\'m new to the concepts of observables and need some help with a conversion.
I have a service which returns an Observable from a Http request,

Answer 1

As of angular 4.3 this can be done automatically.

Example:

export class SomeService {
    constructor(private http: HttpClient) {}  // <--- NOTE: HttpClient instead of Http

    getSome(): Observable {
        return this.http.get('myUrl');
    }
}

So in your case that would be:

return this.http.post(Constants.WEBSERVICE_ADDRESS + "/priceTag", null, {headers: headers});

Again, use the HttpClient instead of Http
