Tutorial: Mengekstrak data pengguna dengan Angular SPA

Berlaku untuk: Penyewa tenaga kerja Penyewa eksternal (pelajari selengkapnya)

Tutorial ini adalah bagian akhir dari seri yang menunjukkan pembuatan aplikasi satu halaman (SPA) Angular dan menambahkan autentikasi menggunakan platform identitas Microsoft. Di Bagian 2 dari seri ini, Anda membuat Angular SPA dan menyiapkannya untuk autentikasi dengan tenant kerja Anda.

Dalam tutorial ini, Anda

• Tambahkan pemrosesan data ke aplikasi Angular Anda.
• Uji aplikasi dan ekstrak data pengguna.

Untuk mengonfigurasi aplikasi Angular Anda untuk berinteraksi dengan Microsoft Graph API, selesaikan langkah-langkah berikut:

1. Buka file src/app/profile/profile.component.ts dan ganti konten dengan cuplikan kode berikut:

   // Required for Angular
   import { Component, OnInit } from '@angular/core';
   
   // Required for the HTTP GET request to Graph
   import { HttpClient } from '@angular/common/http';
   
   type ProfileType = {
     businessPhones?: string,
     displayName?: string,
     givenName?: string,
     jobTitle?: string,
     mail?: string,
     mobilePhone?: string,
     officeLocation?: string,
     preferredLanguage?: string,
     surname?: string,
     userPrincipalName?: string,
     id?: string
   }
   
   @Component({
     selector: 'app-profile',
     templateUrl: './profile.component.html'
   })
   export class ProfileComponent implements OnInit {
     profile!: ProfileType;
     tokenExpiration!: string;
   
     constructor(
       private http: HttpClient
     ) { }
   
     // When the page loads, perform an HTTP GET request from the Graph /me endpoint
     ngOnInit() {
       this.http.get('https://graph.microsoft.com/v1.0/me')
         .subscribe(profile => {
           this.profile = profile;
         });
   
       this.tokenExpiration = localStorage.getItem('tokenExpiration')!;
     }
   }
   

   ProfileComponent di Angular mengambil data profil pengguna dari endpoint /me Microsoft Graph. Ini mendefinisikan ProfileType untuk menyusun properti seperti displayName dan mail. Dalam ngOnInit, ia menggunakan HttpClient untuk mengirim permintaan GET, menetapkan respons ke profile. Ini juga mengambil dan menyimpan waktu kedaluwarsa token dari localStorage di tokenExpiration.

2. Buka file src/app/profile/profile.component.html dan ganti konten dengan cuplikan kode berikut:

   <div class="profile">
       <p><strong>Business Phones:</strong> {{profile?.businessPhones}}</p>
       <p><strong>Display Name:</strong> {{profile?.displayName}}</p>
       <p><strong>Given Name:</strong> {{profile?.givenName}}</p>
       <p><strong>Job Title:</strong> {{profile?.jobTitle}}</p>
       <p><strong>Mail:</strong> {{profile?.mail}}</p>
       <p><strong>Mobile Phone:</strong> {{profile?.mobilePhone}}</p>
       <p><strong>Office Location:</strong> {{profile?.officeLocation}}</p>
       <p><strong>Preferred Language:</strong> {{profile?.preferredLanguage}}</p>
       <p><strong>Surname:</strong> {{profile?.surname}}</p>
       <p><strong>User Principal Name:</strong> {{profile?.userPrincipalName}}</p>
       <p><strong>Profile Id:</strong> {{profile?.id}}</p>
       <br><br>
       <p><strong>Token Expiration:</strong> {{tokenExpiration}}</p>
       <br><br>
       <p>Refreshing this page will continue to use the cached access token until it nears expiration, at which point a new access token will be requested.</p>
   </div>
   

   Kode ini menentukan templat HTML yang menampilkan informasi profil pengguna, menggunakan sintaks interpolasi Angular untuk mengikat properti dari objek profile (Misalnya,, businessPhones, displayName, jobTitle). Ini juga menunjukkan nilai tokenExpiration dan menyertakan catatan yang menyatakan bahwa me-refresh halaman akan menggunakan token akses yang di-cache sampai mendekati kedaluwarsa, setelah itu token baru akan diminta.

Anda akan mengonfigurasi aplikasi Angular untuk menampilkan klaim dalam token ID Anda saat masuk.

1. Buat file yang disebut claim-utils.ts di folder src/app/ dan tempelkan cuplikan kode berikut ke dalamnya.

Untuk menguji aplikasi, selesaikan langkah-langkah berikut:

1. Jalankan aplikasi Angular dengan menjalankan perintah berikut di terminal:

   ng serve --open
   

2. Pilih tombol Masuk untuk mengautentikasi dengan tenant Microsoft Entra Anda.

3. Setelah masuk, pilih tautan Tampilkan Profil untuk menavigasi ke halaman Profil. Verifikasi bahwa informasi profil pengguna ditampilkan, termasuk nama pengguna, email, jabatan, dan detail lainnya.

   

4. Pilih tombol Keluar untuk keluar dari aplikasi.

penyewa eksternal

1. Mulai server web dengan menjalankan perintah berikut pada prompt baris perintah dari folder aplikasi:

   npm install
   npm start
   

2. Di browser Anda, masukkan http://localhost:4200 untuk membuka aplikasi.

   

3. Pilih tombol Login di sudut kanan atas layar.
