導入用戶

透過集合功能整理內容 你可以依據偏好儲存及分類內容。

Firebase Admin SDK 提供了Auth.importUsers() API,用於將用戶批量導入到具有提升權限的 Firebase 身份驗證中。雖然Firebase CLI也提供此功能,但 Admin SDK 允許您以編程方式從外部身份驗證系統或其他 Firebase 項目上傳現有用戶,而無需創建中間 CSV 或 JSON 文件。

用戶導入 API 具有以下優點:

  • 能夠使用不同的密碼散列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。
  • 優化快速高效的批量導入操作。此操作在不檢查uidemailphoneNumber或其他標識符重複的情況下處理用戶。
  • 能夠遷移現有的或創建新的 OAuth 用戶(Google、Facebook 等)。
  • 能夠直接批量導入具有自定義聲明的用戶。

用法

在單個 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,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。導入具有重複的任何其他字段(例如email )的用戶將導致具有相同值的附加用戶。因此,當您使用此 API 時,您必須確保不重複任何唯一字段。

節點.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'),
  },
  //...
];

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,指定了散列選項以幫助 Firebase 在這些用戶下次嘗試使用 Firebase 身份驗證登錄時安全地對其進行身份驗證。成功登錄後,Firebase 會使用內部 Firebase 散列算法重新散列用戶密碼。在下面了解有關每個算法所需字段的更多信息。

即使發生特定於用戶的錯誤,Firebase 身份驗證也會嘗試上傳提供的用戶的整個列表。該操作返回帶有成功和失敗導入摘要的結果。每個失敗的用戶導入都會返回錯誤詳細信息。

如果不需要密碼散列(電話號碼、自定義令牌用戶、OAuth 用戶等),請不要提供散列選項。

使用 Firebase scrypt 哈希密碼導入用戶

默認情況下,Firebase 使用經過修改的 Firebase 版本的 scrypt 哈希算法來存儲密碼。導入使用修改後的 scrypt 散列的密碼對於從另一個現有 Firebase 項目遷移用戶很有用。為此,需要確定原始項目的內部參數。

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,請導航到 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菜單中選擇“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 編碼提供的鹽分隔符(可選)。
  • rounds :用於散列密碼的輪數。
  • memoryCost :此算法所需的內存成本。

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

使用 BCRYPT 散列密碼導入用戶

對於 BCRYPT 散列密碼,既不需要額外的散列參數,也不需要每個用戶的密碼鹽。

節點.js

getAuth()
  .importUsers(
    [
      {
        uid: 'some-uid',
        email: 'user@example.com',
        // Must be provided in a byte buffer.
        passwordHash: Buffer.from('password-hash'),
      },
    ],
    {
      hash: {
        algorithm: 'BCRYPT',
      },
    }
  )
  .then((results) => {
    results.errors.forEach((indexedError) => {
      console.log(`Error importing user ${indexedError.index}`);
    });
  })
  .catch((error) => {
    console.log('Error importing users :', error);
  });

        new ImportUserRecordArgs()
        {
            Uid = "some-uid",

    }

catch (FirebaseAuthException e)
{
    Console.WriteLine($"Error importing users: {e.Message}");

使用 Argon2 散列密碼導入用戶

您可以通過構造Argon2哈希對象來導入具有 Argon2 哈希密碼的用戶記錄。請注意,目前僅在 Admin Java SDK 中支持此功能。

構造此算法的哈希選項所需的參數包括:

  • hashLengthBytes :所需的哈希長度(以字節為單位),以整數形式提供
  • hashType :要使用的 Argon2 變體( ARGON2_DARGON2_IDARGON2_I
  • parallelism :並行度,以整數形式提供。必須介於 1 到 16(含)之間
  • iterations :要執行的迭代次數,以整數形式提供。必須介於 1 到 16(含)之間
  • memoryCostKib :此算法所需的內存成本(以千字節為單位),必須小於 32768。
  • version :Argon2 算法的版本( VERSION_10VERSION_13 )。可選,如果未指定,則默認為 VERSION_13。
  • associatedData :附加的關聯數據,以字節數組的形式提供,附加到哈希值以提供額外的安全層。可選,此數據在發送到 API 之前經過 base64 編碼。

    System.out.println("Failed to import user: " + indexedError.getReason());
  }
} catch (FirebaseAuthException e) {
  System.out.println("Error importing users: " + e.getMessage());
}

導入無密碼用戶

您可以導入沒有密碼的用戶。沒有密碼的用戶可以與具有 OAuth 提供者、自定義聲明和電話號碼等的用戶一起導入。

節點.js

getAuth()
  .importUsers([
    {
      uid: 'some-uid',
      displayName: 'John Doe',
      email: 'johndoe@gmail.com',

      emailVerified: true,
      phoneNumber: '+11234567890',
      // Set this user as admin.
      customClaims: { admin: true },
      // User with Google provider.
      providerData: [
        {
          uid: 'google-uid',
          email: 'johndoe@gmail.com',
