導入用戶

Firebase Admin SDK提供了auth.importUsers() API,用於使用提升的權限將用戶批量導入Firebase身份驗證。儘管Firebase CLI中也提供了此功能,但Admin SDK允許您以編程方式從外部身份驗證系統或其他Firebase項目上載現有用戶,而無需創建中間CSV或JSON文件。

用戶導入API具有以下優點:

  • 能夠使用其他密碼哈希算法從外部身份驗證系統遷移用戶。
  • 能夠從另一個Firebase項目遷移用戶。
  • 優化快速高效的大宗進口業務。此操作處理用戶時無需檢查uidemailphoneNumber或其他標識符重複。
  • 能夠遷移現有或創建新的OAuth用戶(Google,Facebook等)。
  • 可以直接批量導入具有自定義聲明的用戶。

用法

一個API調用中最多可以導入1000個用戶。請注意,此操作針對速度進行了優化,並且不檢查uidemailphoneNumber和其他唯一標識符重複。導入與現有uid衝突的用戶將替換現有用戶。導入其他任何重複字段(例如email )的用戶,將導致其他用戶具有相同的值。因此,在使用此API時,必須確保不重複任何唯一字段。

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()
    .setUid("uid1")
    .setEmail("user1@example.com")
    .setPasswordHash("passwordHash1".getBytes())
    .setPasswordSalt("salt1".getBytes())
    .build());
users.add(ImportUserRecord.builder()
    .setUid("uid2")
    .setEmail("user2@example.com")
    .setPasswordHash("passwordHash2".getBytes())
    .setPasswordSalt("salt2".getBytes())
    .build());

# Up to 1000 users can be imported at once.

        password_hash=b'password_hash_1',

// Up to 1000 users can be imported at once.
var users []*auth.UserToImport
users = append(users, (&auth.UserToImport{}).
	UID("uid1").
	Email("user1@example.com").
	PasswordHash([]byte("passwordHash1")).
	PasswordSalt([]byte("salt1")))
users = append(users, (&auth.UserToImport{}).
	UID("uid2").
	Email("user2@example.com").
	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 = "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"),
    },
};

在此示例中,指定了哈希選項以幫助Firebase在下一次嘗試使用Firebase身份驗證登錄時對這些用戶進行安全身份驗證。成功登錄後,Firebase會使用內部Firebase哈希算法重新哈希用戶的密碼。在下面了解有關每種算法必填字段的更多信息。

即使發生特定於用戶的錯誤,Firebase身份驗證也會嘗試上載所提供用戶的整個列表。該操作返回結果,其中包含成功導入和失敗導入的摘要。每次失敗的用戶導入都會返回錯誤詳細信息。

如果不需要密碼哈希(電話號碼,自定義令牌用戶,OAuth用戶等),請不要提供哈希選項。

使用MD5,SHA和PBKDF哈希密碼導入用戶

MD5,SHA和PBKDF哈希算法包括: MD5SHA1SHA256SHA512PBKDF_SHA1PBKDF2_SHA256 。對於這些哈希算法,必須提供用於對密碼進行哈希處理的回合數(對於MD5為0到8192之間,對於SHA1SHA256SHA512為1到8192之間,對於PBKDF_SHA1PBKDF2_SHA256為0到120000之間)。

使用標準的SCRYPT哈希密碼導入用戶

Firebase身份驗證支持標準SCRYPT算法以及內部修改版本。對於標準SCRYPT算法,需要以下哈希參數:

  • memoryCost :哈希算法的CPU /內存成本。
  • parallelization :哈希算法的並行化。
  • blockSize :哈希算法的塊大小(通常為8)。
  • derivedKeyLength :哈希算法的派生密鑰長度

使用Firebase SCRYPT哈希密碼導入用戶

導入使用經過修改的Firebase版本的SCRYPT哈希算法進行哈希處理的密碼,對於從另一個現有Firebase項目遷移用戶非常有用。為此,需要為原始項目確定內部參數。

Firebase為每個Firebase項目生成唯一的密碼哈希參數。要訪問這些參數,請導航至Firebase控制台中的“用戶”選項卡,然後從用戶表列表右上角的下拉列表中選擇“密碼哈希參數”

構造此算法的哈希選項所需的參數包括:

  • key :通常以base64編碼提供的簽名者密鑰。
  • saltSeparator :通常以base64編碼提供的鹽分離器(可選)。
  • rounds :用於散列密碼的回合數。
  • memoryCost :此算法所需的內存成本。

導入沒有密碼的用戶

您可以導入沒有密碼的用戶。可以將沒有密碼的用戶與具有OAuth提供程序,自定義聲明和電話號碼等的用戶一起導入。
