javascript - 放大联合登录不返回 Facebook 的电子邮件

Question

我正在使用 AWS Amplify 添加社交签名。通过谷歌，我收到了用户的电子邮件，但它在 facebook 中丢失了。
这是我的代码:

  federatedSignIn(provider: any): void {
    switch (provider) {
      case 'facebook':
          console.log("Authenticating using Facebook");
          Auth.federatedSignIn({ provider: CognitoHostedUIIdentityProvider.Facebook });
          break;
      case 'google':
        console.log("Authenticating using Google");
        Auth.federatedSignIn({ provider: CognitoHostedUIIdentityProvider.Google });
        break;
    }
     
  }

这就是“预注册” Lambda 所认为的事件。

{
    "version": "1",
    "region": "us-east-1",
    "userPoolId": "us-east-xxxxxx",
    "userName": "Facebook_123456",
    "callerContext": {
        "awsSdkVersion": "aws-sdk-unknown-unknown",
        "clientId": "123456abcd"
    },
    "triggerSource": "PreSignUp_ExternalProvider",
    "request": {
        "userAttributes": {
            "email_verified": "false",
            "cognito:email_alias": "",
            "phone_number_verified": "false",
            "cognito:phone_number_alias": ""
        },
        "validationData": {}
    },
    "response": {
        "autoConfirmUser": false,
        "autoVerifyEmail": false,
        "autoVerifyPhone": false
    }
}

用户池设置


属性映射

Answer 1

问题在于 <amplify-facebook-button>因为它使用身份池工作流而不是用户池工作流。使用 federatedSignIn() 创建自定义按钮工作。

  <button  slot="federated-buttons" (click)=customSignIn()>Facebook</button>

  customSignIn(): void{
    Auth.federatedSignIn({provider: CognitoHostedUIIdentityProvider.Facebook });
  }
