Ionic2 - http get is not working - ionic-framework

Question

I have written a authentication service to authenticate user name and password in a Login Page. The code below is the service.
public login(credentials) {
if (credentials.username === null || credentials.password === null) {
return Observable.throw("Please insert credentials");
} else {
let apiURL = 'http://localhost/timeclock/api/login?usercode=' + credentials.username +
'&password=' + credentials.password ;
return Observable.create(observer => {
this.http.get(apiURL).map(res => res.json()).subscribe(data => {
if (data.success === 'true')
{
this.currentUser.name = data.data.user_name;
this.currentUser.email = data.data.user_email;
observer.next(true);
observer.complete();
} else {
observer.next(false);
observer.complete();
}
});
});
}
}
When the user name and password is submitted, the URL is correctly called with the right parameters.
The http call takes very long time to complete. Also, no response is returned.
It takes only two or three seconds to get the response when I call the URL with the same parameters in the browser.
Any idea on how to fix this?

You don't need to create a new Observable you can refactor like this.
public login(credentials) : Observable<boolean> {
if (credentials.username === null || credentials.password === null) {
return Observable.throw("Please insert credentials");
} else {
let apiURL = 'http://localhost/timeclock/api/login?usercode=' + credentials.username +
'&password=' + credentials.password ;
return this.http.get(apiURL).map(res => res.json())
.map(data =>
{
if(data.success){
this.currentUser.name = data.data.user_name;
this.currentUser.email = data.data.user_email;
return true;
}else{
return false;
}
});
}
}
