Catching Rejections

To catch rejections we use the subscriber's error and complete callbacks.
1
import { HttpClient } from '@angular/http/common';
2
import { Injectable } from '@angular/core';
3
​
4
@Injectable()
5
export class AuthService {
6
​
7
  constructor(private http: HttpClient) {}
8
​
9
  login(username, password) {
10
    const payload = {
11
      username: username,
12
      password: password
13
    };
14
​
15
    this.http.post(`${ BASE_URL }/auth/login`, payload)
16
      .pipe(map(response => response.json()))
17
      .subscribe(
18
        authData => this.storeToken(authData.id_token),
19
        (err) => console.error(err),
20
        () => console.log('Authentication Complete')
21
      );
22
  }
23
}
