Importa utenti

Il Firebase Admin SDK fornisce le Auth.importUsers() API per importare utenti in massa di autenticazione Firebase con privilegi elevati. Anche se questa funzione è disponibile anche nel Firebase CLI , l'SDK di amministrazione consente di caricare gli utenti esistenti da un sistema di autenticazione esterno o un altro progetto Firebase di programmazione senza dover creare CSV intermedio o file JSON.

L'API di importazione utenti offre i seguenti vantaggi:

  • Possibilità di migrare gli utenti da un sistema di autenticazione esterno utilizzando un diverso algoritmo di hashing delle password.
  • Possibilità di migrare gli utenti da un altro progetto Firebase.
  • Ottimizzazione per operazioni di importazione di massa rapide ed efficienti. Questa operazione elabora gli utenti senza controllare per uid , email , phoneNumber o altra duplicazione identificativo.
  • Possibilità di migrare esistenti o creare nuovi utenti OAuth (Google, Facebook, ecc.).
  • Possibilità di importare utenti con attestazioni personalizzate direttamente in blocco.

Utilizzo

È possibile importare fino a 1000 utenti in una singola chiamata API. Si noti che questa operazione è ottimizzato per la velocità e non controlla uid , email , phoneNumber e altre duplicazioni identificatore univoco. Importazione di un utente che si scontra con un esistente uid sostituirà l'utente esistente. Importazione di un utente con qualsiasi altro campo duplicati (ad esempio email ) si tradurrà in un altro utente con lo stesso valore. Di conseguenza, quando utilizzi questa API, devi assicurarti di non duplicare alcun campo univoco.

Nodo.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'),
  },
  //...
];

C#

//  Up to 1000 users can be imported at once.
var users = new List<ImportUserRecordArgs>()
{
    new ImportUserRecordArgs()
    {
        Uid = "uid1",
        Email = "user1@example.com",
        PasswordHash = Encoding.ASCII.GetBytes("passwordHash1"),
        PasswordSalt = Encoding.ASCII.GetBytes("salt1"),
    },
    new ImportUserRecordArgs()
    {
        Uid = "uid2",
        Email = "user2@example.com",
        PasswordHash = Encoding.ASCII.GetBytes("passwordHash2"),
        PasswordSalt = Encoding.ASCII.GetBytes("salt2"),
    },
};

In questo esempio, le opzioni di hashing sono specificate per aiutare Firebase ad autenticare in modo sicuro questi utenti la prossima volta che tenteranno di accedere con Firebase Authentication. Una volta eseguito l'accesso, Firebase esegue nuovamente l'hashing della password dell'utente con l'algoritmo di hashing interno di Firebase. Ulteriori informazioni sui campi obbligatori per algoritmo di seguito.

L'autenticazione Firebase tenta di caricare l'intero elenco di utenti forniti anche quando si verifica un errore specifico dell'utente. L'operazione restituisce un risultato con il riepilogo delle importazioni riuscite e non riuscite. I dettagli dell'errore vengono restituiti per ogni importazione utente non riuscita.

Se non è necessario l'hashing della password (numero di telefono, utente token personalizzato, utente OAuth e così via), non fornire opzioni di hashing.

Importa utenti con password con hash scrypt Firebase

Per impostazione predefinita, Firebase utilizza una versione modificata Firebase dell'algoritmo scrypt hashing per memorizzare le password. L'importazione delle password con hash modificato è utile per la migrazione degli utenti da un altro progetto Firebase esistente. Per fare ciò, è necessario determinare i parametri interni per il progetto originale.

Firebase genera parametri hash password univoci per ogni progetto Firebase. Per accedere a questi parametri, accedere alla scheda Utenti nella console Firebase e selezionare parametri hash della password dal menu a discesa nell'angolo in alto a destra la lista delle tabelle di utenti.

I parametri necessari per costruire le opzioni hash per questo algoritmo includono:

  • key : la chiave firmatario normalmente previsto nella codifica base64.
  • saltSeparator : il separatore sale normalmente disponibile in base64 codifica (opzionale).
  • rounds : il numero di giri utilizzati per hash delle password.
  • memoryCost : il costo di memoria richiesta per questo algoritmo.

Importa utenti con password con hash scrypt standard

L'autenticazione Firebase supporta l'algoritmo scrypt standard e la versione modificata (sopra). Per l'algoritmo scrypt standard, sono richiesti i seguenti parametri di hashing:

  • memoryCost : il costo di CPU / memoria del algoritmo di hashing.
  • parallelization : la parallelizzazione degli algoritmi di hashing.
  • blockSize : la dimensione del blocco (normalmente 8) dell'algoritmo di hashing.
  • derivedKeyLength : La lunghezza della chiave derivato dell'algoritmo di hashing
