在創建用戶池時，我希望用戶能夠使用他們的 email 或電話作為他們的用戶名。

這樣就完成了，我總是需要同時發送 email 和電話號碼。

有誰知道我如何解決這個問題？

我希望用戶能夠通過輸入以下信息之一進行登錄：

• email + 姓名
• 電話號碼+姓名

有人幫幫我嗎？

Answer 1

用戶可以使用此 SAM 模板使用他們的 email 或電話號碼登錄，並在注冊時使用隨機 uuid 作為用戶名。

UserPool:
    Type: "AWS::Cognito::UserPool"
    Properties:
      UserPoolName: !Ref UserPoolName
      Schema:
        - Name: phone_number
          AttributeDataType: String
          Mutable: true
        - Name: email
          AttributeDataType: String
          Mutable: true
      Policies:
        PasswordPolicy:
          MinimumLength: 6
          RequireLowercase: false
          RequireNumbers: false
          RequireSymbols: false
          RequireUppercase: false
      AliasAttributes:
        - email
        - phone_number
      MfaConfiguration: "OFF"

但是現在我需要知道別名用戶在登錄時使用，有人知道怎么做嗎？

我正在使用 cognito 進行無密碼流程，create-auth-lambda 觸發器上的事件始終相同。
