How do I handle errors in the Service, and Subscribe to responses in the
Component?
Previously I have setup my Services like so:
post(user: User): Observable<User> {
const options = new RequestOptions({headers: this.headers});
return this.http.post('/api/auth', JSON.stringify(user), options)
.map(response => {
this.accessToken = response.headers.get('x-access-token');
return response.json()
})
.catch(handleError);
}
Which is useful because the calling Component can then easily:
this.authService.post(user).subscribe(user => {
if (!this.authService.isLoggedIn()) {
this.alertsService.alerts.push({msg: JSON.stringify(user), type:
'warning'});
return;
}
this.alertsService.alerts.push({msg: `Logged in with
${this.authService.accessToken}`, type: 'success'});
this.router.navigate(['/contacts']);
}, error => this.alertsService.alerts.push({msg: error, type: 'danger'}));
I want to move to the new HttpClient ASAP, because of your retry features
and especially the reintroduction of interceptors from AngularJS. Then my
auth pipeline will work with less hacks!
Thanks for all suggestions
