Impor Pengguna

Tetap teratur dengan koleksi Simpan dan kategorikan konten berdasarkan preferensi Anda.

Firebase Admin SDK menyediakan Auth.importUsers() API untuk mengimpor pengguna secara massal ke Firebase Authentication dengan hak istimewa yang lebih tinggi. Meskipun fitur ini juga tersedia di Firebase CLI , Admin SDK memungkinkan Anda mengunggah pengguna yang ada dari sistem autentikasi eksternal atau proyek Firebase lainnya secara terprogram tanpa harus membuat file CSV atau JSON perantara.

API impor pengguna menawarkan keuntungan berikut:

  • Kemampuan untuk memigrasikan pengguna dari sistem otentikasi eksternal menggunakan algoritma hashing kata sandi yang berbeda.
  • Kemampuan untuk memigrasikan pengguna dari proyek Firebase lain.
  • Optimalisasi untuk operasi impor massal yang cepat dan efisien. Operasi ini memproses pengguna tanpa memeriksa uid , email , phoneNumber atau duplikasi pengenal lainnya.
  • Kemampuan untuk memigrasikan pengguna OAuth yang ada atau membuat baru (Google, Facebook, dll).
  • Kemampuan untuk mengimpor pengguna dengan klaim khusus secara langsung dalam jumlah besar.

Penggunaan

Hingga 1000 pengguna dapat diimpor dalam satu panggilan API. Perhatikan bahwa operasi ini dioptimalkan untuk kecepatan dan tidak memeriksa uid , email , phoneNumber dan duplikasi pengenal unik lainnya. Mengimpor pengguna yang bertabrakan dengan uid yang ada akan menggantikan pengguna yang ada. Mengimpor pengguna dengan bidang lain yang diduplikasi (misalnya email ) akan menghasilkan pengguna tambahan dengan nilai yang sama. Akibatnya, saat Anda menggunakan API ini, Anda harus memastikan bahwa Anda tidak menduplikasi bidang unik apa pun.

Node.js

// Up to 1000 users can be imported at once.
const userImportRecords = [
  {
    uid: 'uid1',
    email: 'user1@example.com',
    passwordHash: Buffer.from('passwordHash1'),
    passwordSalt: Buffer.from('salt1'),
  },
  {
    uid: 'uid2',
    email: 'user2@example.com',
    passwordHash: Buffer.from('passwordHash2'),
    passwordSalt: Buffer.from('salt2'),
  },
  //...
];

// Up to 1000 users can be imported at once.
List<ImportUserRecord> users = new ArrayList<>();
users.add(ImportUserRecord.builder()

        Uid = "uid1",
        Email = "user1@example.com",

        PasswordHash = Encoding.ASCII.GetBytes("passwordHash2"),
        PasswordSalt = Encoding.ASCII.GetBytes("salt2"),

};

Dalam contoh ini, opsi hashing ditentukan untuk membantu Firebase mengautentikasi pengguna ini dengan aman saat mereka mencoba masuk lagi dengan Firebase Authentication. Saat berhasil masuk, Firebase akan meng-hash ulang kata sandi pengguna dengan algoritme internal Firebase hashing. Pelajari lebih lanjut tentang bidang wajib per algoritme di bawah ini.

Firebase Authentication mencoba mengupload seluruh daftar pengguna yang disediakan bahkan saat terjadi kesalahan khusus pengguna. Operasi mengembalikan hasil dengan ringkasan impor yang berhasil dan gagal. Detail kesalahan dikembalikan per impor pengguna yang gagal.

Impor pengguna dengan sandi hash scrypt Firebase

Secara default, Firebase menggunakan versi Firebase yang dimodifikasi dari algoritma hashing scrypt untuk menyimpan kata sandi. Mengimpor sandi yang di-hash dengan scrypt yang dimodifikasi berguna untuk memigrasikan pengguna dari proyek Firebase lain yang sudah ada. Untuk melakukannya, parameter internal perlu ditentukan untuk proyek asli.

Firebase menghasilkan parameter hash sandi unik untuk setiap proyek Firebase. Untuk mengakses parameter ini, navigasikan ke tab Pengguna di konsol Firebase dan pilih Parameter Hash Kata Sandi dari tarik-turun di sudut kanan atas daftar tabel pengguna.

Parameter yang diperlukan untuk membangun opsi hash untuk algoritma ini meliputi:

  • key : kunci penandatangan biasanya disediakan dalam pengkodean base64.
  • saltSeparator : pemisah garam biasanya disediakan dalam pengkodean base64 (opsional).
  • rounds : jumlah putaran yang digunakan untuk hash kata sandi.
  • memoryCost : biaya memori yang diperlukan untuk algoritma ini.

Impor pengguna dengan kata sandi hash scrypt standar

Firebase Authentication mendukung algoritme scrypt standar serta versi yang dimodifikasi (di atas). Untuk algoritma scrypt standar, parameter hashing berikut diperlukan:

  • memoryCost : biaya CPU/memori dari algoritma hashing.
  • parallelization : paralelisasi algoritma hashing.
  • blockSize : ukuran blok (biasanya 8) dari algoritma hashing.
  • derivedKeyLength : Panjang kunci turunan dari algoritma hashing

Impor pengguna dengan kata sandi hash Argon2

Anda dapat mengimpor catatan pengguna yang memiliki kata sandi hash Argon2 dengan membuat objek hash Argon2 . Perhatikan bahwa saat ini hanya didukung di Admin Java SDK.

Parameter yang diperlukan untuk membangun opsi hash untuk algoritma ini meliputi:

  • hashLengthBytes : panjang hash yang diinginkan dalam byte, disediakan sebagai bilangan bulat
  • hashType : varian Argon2 yang akan digunakan ( ARGON2_D , ARGON2_ID , ARGON2_I )
  • parallelism : derajat paralelisme, diberikan sebagai bilangan bulat. Harus antara 1 dan 16 (termasuk)
  • iterations : jumlah iterasi yang harus dilakukan, disediakan sebagai bilangan bulat. Harus antara 1 dan 16 (termasuk)
  • memoryCostKib : biaya memori yang diperlukan untuk algoritma ini dalam kibibyte, harus kurang dari 32768.
  • version : versi algoritma Argon2 ( VERSION_10 atau VERSION_13 ). Opsional, default ke VERSION_13 jika tidak ditentukan.
  • associatedData : data terkait tambahan, disediakan sebagai array byte, yang ditambahkan ke nilai hash untuk memberikan lapisan keamanan tambahan. Opsional, data ini dienkode base64 sebelum dikirim ke API.

  List<ImportUserRecord> users = Collections.singletonList(ImportUserRecord.builder()

Impor pengguna tanpa kata sandi

Anda dapat mengimpor pengguna tanpa kata sandi. Pengguna tanpa kata sandi dapat diimpor dalam kombinasi dengan pengguna yang memiliki penyedia OAuth, klaim khusus dan nomor telepon, dan sebagainya.
