Mengimpor Pengguna

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

API untuk operasi impor pengguna menawarkan keuntungan berikut:

• Kemampuan untuk memigrasi pengguna dari sistem autentikasi eksternal menggunakan algoritme hashing sandi yang berbeda.
• Kemampuan untuk memigrasi pengguna dari project Firebase lain.
• Pengoptimalan untuk operasi impor secara massal yang cepat dan efisien. Operasi ini memproses pengguna tanpa memeriksa uid, email, phoneNumber, atau duplikasi ID lainnya.
• Kemampuan untuk memigrasi pengguna OAuth yang sudah ada atau membuat pengguna baru (Google, Facebook, dll.).
• Kemampuan untuk langsung mengimpor pengguna dengan klaim kustom secara massal.

Penggunaan

Hingga 1.000 pengguna dapat diimpor dalam satu panggilan API. Perlu diperhatikan bahwa operasi ini dioptimalkan untuk tujuan kecepatan, dan tidak memeriksa uid, email, phoneNumber, dan duplikasi ID unik lainnya. Mengimpor pengguna yang bentrok dengan uid yang ada akan menggantikan pengguna yang ada. Mengimpor pengguna yang memiliki kolom duplikat lain (misalnya email) akan menghasilkan pengguna tambahan dengan nilai yang sama. Akibatnya, Anda harus memastikan bahwa Anda tidak menduplikat kolom unik mana pun saat menggunakan API ini.

Node.js

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

Java

// Up to 1000 users can be imported at once.
List<ImportUserRecord> users = new ArrayList<>();
users.add(ImportUserRecord.builder()
    .setUid("uid1")
    .setEmail("[e-mail]")
    .setPasswordHash("passwordHash1".getBytes())
    .setPasswordSalt("salt1".getBytes())
    .build());
users.add(ImportUserRecord.builder()
    .setUid("uid2")
    .setEmail("[e-mail]")
    .setPasswordHash("passwordHash2".getBytes())
    .setPasswordSalt("salt2".getBytes())
    .build());

Python

# Up to 1000 users can be imported at once.
users = [
    auth.ImportUserRecord(
        uid='uid1',
        email='[e-mail]',
        password_hash=b'password_hash_1',
        password_salt=b'salt1'
    ),
    auth.ImportUserRecord(
        uid='uid2',
        email='[e-mail]',
        password_hash=b'password_hash_2',
        password_salt=b'salt2'
    ),
]

Go

// Up to 1000 users can be imported at once.
var users []*auth.UserToImport
users = append(users, (&auth.UserToImport{}).
	UID("uid1").
	Email("[e-mail]").
	PasswordHash([]byte("passwordHash1")).
	PasswordSalt([]byte("salt1")))
users = append(users, (&auth.UserToImport{}).
	UID("uid2").
	Email("[e-mail]").
	PasswordHash([]byte("passwordHash2")).
	PasswordSalt([]byte("salt2")))

C#

//  Up to 1000 users can be imported at once.
var users = new List<ImportUserRecordArgs>()
{
    new ImportUserRecordArgs()
    {
        Uid = "uid1",
        Email = "[e-mail]",
        PasswordHash = Encoding.ASCII.GetBytes("passwordHash1"),
        PasswordSalt = Encoding.ASCII.GetBytes("salt1"),
    },
    new ImportUserRecordArgs()
    {
        Uid = "uid2",
        Email = "[e-mail]",
        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 dia mencoba login kembali dengan Firebase Authentication. Saat berhasil login, Firebase akan kembali melakukan hash sandi pengguna dengan algoritme hashing Firebase internal. Pelajari lebih lanjut kolom wajib diisi per algoritme di bawah ini.

Firebase Authentication mencoba mengupload seluruh daftar pengguna yang disediakan, meskipun terjadi error khusus pengguna. Operasi tersebut menampilkan hasil berisi ringkasan impor yang berhasil dan gagal. Detail error ditampilkan per impor pengguna yang gagal.

Jika hashing sandi tidak diperlukan (nomor telepon, pengguna token kustom, pengguna OAuth, dll.), jangan berikan opsi hashing.

Mengimpor pengguna dengan sandi yang di-hash scrypt Firebase

Secara default, Firebase menggunakan versi Firebase yang dimodifikasi dari algoritme hashing scrypt untuk menyimpan sandi. Mengimpor sandi yang di-hash dengan scrypt yang dimodifikasi berguna untuk memigrasikan pengguna dari project Firebase lain yang ada. Untuk melakukannya, parameter internal harus ditentukan untuk project asalnya.

Firebase menghasilkan parameter hash sandi yang unik untuk setiap project Firebase. Untuk mengakses parameter ini, buka tab Users di Firebase console lalu pilih Password Hash Parameters dari menu drop-down di pojok kanan atas daftar tabel pengguna.

Parameter yang diperlukan dalam membuat opsi hash untuk algoritme ini meliputi:

• key: kunci penanda yang biasanya disediakan dalam encoding base64.
• saltSeparator: pemisah salt yang biasanya disediakan dalam encoding base64 (opsional).
• rounds: jumlah putaran yang digunakan untuk hashing sandi.

• memoryCost: biaya memori yang diperlukan untuk algoritme ini.

Mengimpor pengguna dengan sandi yang di-hash scrypt standar

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

• memoryCost: biaya CPU/memori dari algoritme hashing.
• parallelization: paralelisasi dari algoritme hashing.
• blockSize: ukuran blok (biasanya 8) dari algoritme hashing.

• derivedKeyLength: Panjang kunci turunan dari algoritme hashing

Algoritme hashing MD5, SHA, dan PBKDF meliputi: MD5, SHA1, SHA256, SHA512, PBKDF_SHA1, dan PBKDF2_SHA256. Untuk algoritma hashing ini, Anda harus menyediakan jumlah putaran (antara 0 hingga 8.192 untuk MD5, antara 1 hingga 8.192 untuk SHA1, SHA256, dan SHA512, serta antara 0 hingga 120.000 untuk PBKDF_SHA1 dan PBKDF2_SHA256) yang digunakan untuk hashing sandi.

Mengimpor pengguna dengan sandi yang di-hash BCRYPT

Mengimpor pengguna dengan sandi yang di-hash Argon2

Anda dapat mengimpor data pengguna yang memiliki sandi yang di-hash Argon2 dengan membuat objek hash Argon2. Perhatikan bahwa perintah tersebut saat ini hanya didukung di Admin Java SDK.

Parameter yang diperlukan dalam membuat opsi hash untuk algoritme ini meliputi:

• hashLengthBytes: panjang hash yang diinginkan dalam byte, diberikan sebagai bilangan bulat
• hashType: varian Argon2 yang akan digunakan (ARGON2_D, ARGON2_ID, ARGON2_I)
• parallelism: tingkat paralelisme, yang diberikan sebagai bilangan bulat. Harus antara 1 dan 16 (inklusif).
• iterations: jumlah iterasi yang akan dijalankan, diberikan sebagai bilangan bulat. Harus antara 1 dan 16 (inklusif).
• memoryCostKib: biaya memori yang diperlukan untuk algoritme ini dalam kibibyte, harus kurang dari 32.768.
• version: versi algoritma Argon2 (VERSION_10 atau VERSION_13). Opsional, ditetapkan secara 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 dengan base64 sebelum dikirim ke API.

Java

try {
  List<ImportUserRecord> users = Collections.singletonList(ImportUserRecord.builder()
      .setUid("some-uid")
      .setEmail("[e-mail]")
      .setPasswordHash("password-hash".getBytes())
      .setPasswordSalt("salt".getBytes())
      .build());
  UserImportOptions options = UserImportOptions.withHash(
      Argon2.builder()
          .setHashLengthBytes(512)
          .setHashType(Argon2HashType.ARGON2_ID)
          .setParallelism(8)
          .setIterations(16)
          .setMemoryCostKib(2048)
          .setVersion(Argon2Version.VERSION_10)
          .setAssociatedData("associated-data".getBytes())
          .build());
  UserImportResult result = FirebaseAuth.getInstance().importUsers(users, options);
  for (ErrorInfo indexedError : result.getErrors()) {
    System.out.println("Failed to import user: " + indexedError.getReason());
  }
} catch (FirebaseAuthException e) {
  System.out.println("Error importing users: " + e.getMessage());
}

Mengimpor pengguna tanpa sandi

Anda dapat mengimpor pengguna tanpa sandi. Pengguna tanpa sandi dapat diimpor bersamaan dengan pengguna yang memiliki penyedia OAuth, nomor telepon dan klaim kustom, dan sebagainya.

Node.js
