I want to check one api call inside an observable which I will subscribe in a component. As written below, I want to run my observable in this manner but it is not working. What changes shall I do to this code to make it work. Whenever I try to subscribe through it especially through the scenario when someObservableWrittenInTheSameService returns with an error 404, I want to return url2.
getfunction(submissionId: string ){
if (some condition) {
this.someObservableWrittenInTheSameService(parameter).subscribe(
(httpValue: any) => {
let url = '';
if (httpValue.code === 200) {
return this.http.get(url1);
}
}, err => {
if (err.code === 404) {
return this.http.get(url2);
}
}
)
}
let url3
return this.http.get(url3);
}
This function is then is called in a component where it is subscribed. But whenever someObservableWrittenInTheSameService return 404, the subscription always fails and go to error block in the component.
