Catching Rejections

To catch rejections we use the subscriber's error and complete callbacks.

import { HttpClient } from '@angular/http/common';
import { Injectable } from '@angular/core';
@Injectable()
export class AuthService {
constructor(private http: HttpClient) {}
login(username, password) {
const payload = {
username: username,
password: password
};
this.http.post(`${ BASE_URL }/auth/login`, payload)
.map(response => response.json())
.subscribe(
authData => this.storeToken(authData.id_token),
(err) => console.error(err),
() => console.log('Authentication Complete')
);
}
}
