Das Firebase Admin SDK bietet die Auth.importUsers()
API, mit der Nutzer mit erhöhten Berechtigungen in Firebase Authentication importiert werden können. Diese Funktion ist zwar auch
in der Firebase CLI
können Sie über das Admin SDK vorhandene Nutzer
Authentifizierungssystem oder eines anderen Firebase-Projekts programmatisch
CSV- oder JSON-Zwischendateien erstellen.
Die Nutzerimport-API bietet folgende Vorteile:
- Möglichkeit, Nutzer mit einem anderen Passwort-Hash-Algorithmus von einem externen Authentifizierungssystem zu migrieren.
- Möglichkeit, Nutzer aus einem anderen Firebase-Projekt zu migrieren.
- Optimierung für einen schnellen und effizienten Bulk-Import. Bei diesem Vorgang werden Nutzer ohne Prüfung auf
uid
,email
,phoneNumber
oder andere Duplikate von IDs verarbeitet. - Möglichkeit, vorhandene OAuth-Nutzer (Google, Facebook usw.) zu migrieren oder neue zu erstellen
- Nutzer mit benutzerdefinierten Ansprüchen können direkt im Bulk-Verfahren importiert werden.
Nutzung
In einem einzelnen API-Aufruf können bis zu 1.000 Nutzer importiert werden. Dieser Vorgang
ist für Geschwindigkeit optimiert und sucht nicht nach uid
, email
, phoneNumber
und
und andere eindeutige Kennungen. Importieren eines Nutzers, der mit einem kollidierenden
Durch das vorhandene uid
wird der vorhandene Nutzer ersetzt. Nutzer mit einem anderen
duplizierten Felds (z.B. email
) einen zusätzlichen Nutzer mit demselben
Wert. Wenn Sie diese API verwenden, müssen Sie daher sicherstellen,
eindeutige Felder dupliziert werden.

In diesem Beispiel werden die Hash-Optionen angegeben, damit Firebase sicher diese Nutzer bei der nächsten Anmeldung mit Firebase Authentication zu authentifizieren. Nach erfolgreicher Anmeldung wird das Passwort des Nutzers von Firebase erneut mit dem internen Firebase-Hash-Algorithmus. Weitere Informationen zu den erforderlichen Feldern pro Algorithmus finden Sie unten.
Firebase Authentication versucht, die gesamte Liste der bereitgestellten Nutzer hochzuladen, auch wenn ein nutzerspezifischer Fehler auftritt. Der Vorgang gibt ein Ergebnis zurück, das die Zusammenfassung erfolgreicher und fehlgeschlagener Importe enthält. Fehlerdetails werden nach einem fehlgeschlagenen Nutzerimport zurückgegeben.

Nutzer mit von Firebase verschlüsselten Passwörtern importieren
Standardmäßig verwendet Firebase einen Modifizierung der Firebase-Version des Verschlüsselungs-Hash-Algorithmus um Passwörter zu speichern. Der Import von mit modifiziertem Scrypt gehashten Passwörtern ist nützlich, um Nutzer aus einem anderen Firebase-Projekt zu migrieren. Dazu müssen die internen Parameter für das ursprüngliche Projekt ermittelt werden.
Firebase generiert für jedes Firebase-Projekt eindeutige Passwort-Hash-Parameter. Sie finden diese Parameter auf dem Tab Nutzer. in der Firebase-Konsole und wählen Sie Password Hash Parameters (Passwort-Hash-Parameter) aus der Drop-down-Menü oben rechts in der Tabellenliste der Nutzer.
Zum Erstellen der Hash-Optionen für diesen Algorithmus sind unter anderem folgende Parameter erforderlich:
key
: der Unterzeichnerschlüssel, der normalerweise in base64-Codierung bereitgestellt wirdsaltSeparator
: Das normalerweise in der Base64-Codierung bereitgestellte Salt-Trennzeichen (optional).rounds
: die Anzahl der Runden, die zum Hashen der Passwörter verwendet werden.memoryCost
: die für diesen Algorithmus erforderlichen Arbeitsspeicherkosten.

Nutzer mit Argon2-Hash-Passwörtern importieren
Sie können Nutzerdatensätze mit mit Argon2 gehashten Passwörtern importieren, indem Sie ein Argon2
-Hashobjekt erstellen. Hinweis: Dies wird derzeit nur unterstützt,
im Admin Java SDK.
Zum Erstellen der Hash-Optionen für diesen Algorithmus sind unter anderem folgende Parameter erforderlich:
hashLengthBytes
: die gewünschte Hash-Länge in Byte, angegeben als GanzzahlhashType
: die zu verwendende Argon2-Variante (ARGON2_D
,ARGON2_ID
,ARGON2_I
)parallelism
: der Grad der Parallelität, angegeben als Ganzzahl. Muss zwischen 1 und 16 (einschließlich) liegeniterations
: die Anzahl der auszuführenden Iterationen, angegeben als Ganzzahl. Muss zwischen 1 und 16 (einschließlich) liegenmemoryCostKib
: Die für diesen Algorithmus erforderlichen Arbeitsspeicherkosten in Kibibyte müssen unter 32.768 liegen.version
: Die Version des Argon2-Algorithmus (VERSION_10
oderVERSION_13
). Optional, Standardwert ist VERSION_13, wenn nicht angegeben.associatedData
: zusätzliche zugehörige Daten, die als Byte-Array bereitgestellt werden und an den Hashwert angehängt werden, um eine zusätzliche Sicherheitsebene zu schaffen. Optional werden diese Daten vor dem Senden an die API base64-codiert.

Nutzer ohne Passwörter importieren
Sie können Nutzer ohne Passwörter importieren. Nutzer ohne Passwort können zusammen mit Nutzern importiert werden, die OAuth-Anbieter, Telefonnummern usw.
