Cognito 從 Pre Sign-up Lambda 觸發器發送什么樣的事件

Question

我創建了一個PreSignup Lambda function 與 Cognito Pre-SignUp 觸發器一起使用，代碼如下：

import { APIGatewayEventDefaultAuthorizerContext, APIGatewayProxyEvent, APIGatewayProxyResult } from 'aws-lambda';

export async function PreSignup(event: any, context: APIGatewayEventDefaultAuthorizerContext,) {
  console.log("...event:", event);
  console.log("...context:", context);

  let userName = event.userName;
  let email = event.request.userAttributes.email;

  console.log("...userName:", userName);
  console.log("...email:", email);

  // Confirming the event so Cogntio doesnt resend it again:
  event.response.autoConfirmUser = true;
  event.response.autoVerifyPhone = true;
  event.response.autoVerifyEmail = true;
  return event;
}

與其使用function PreSignup(event: any)將event設置為any ，我寧願指定事件的類型。

我試圖將其指定為APIGatewayProxyEvent ，如下所示：

function PreSignup(event: APIGatewayProxyEvent, context: APIGatewayEventDefaultAuthorizerContext,) {...}

但它不起作用，因為 Cognito 預注冊觸發器發送的event不是APIGatewayProxyEvent類型。 這是什么活動？

后來編輯：

以下是 Cognito PreSignUp Trigger 推送的復制/粘貼事件：

{
  version: '1',
  region: 'us-east-1',
  userPoolId: 'us-east-1_abcdef',
  userName: 'emailf@address.com',
  callerContext: {
    awsSdkVersion: 'aws-sdk-nodejs-2.799.0',
    clientId: 'CLIENT_ID_NOT_APPLICABLE'
  },
  triggerSource: 'PreSignUp_AdminCreateUser',
  request: {
    userAttributes: { email: 'emailf@address.com' },
    validationData: null
  },
  response: {
    autoConfirmUser: false,
    autoVerifyEmail: false,
    autoVerifyPhone: false
  }
}

下面是AWS EventBridge這次推送的另一個 AWS 事件的示例（類似於 Cognito Trigger 推送的事件）：

{
  version: '0',
  id: '0ee136cb-ea53-f9e0-a6a9-232dfb78b7d0',
  'detail-type': 'UserCreated',
  source: 'my.company.endpointname',
  account: '123456789012',
  time: '2021-01-29T03:05:54Z',
  region: 'us-east-1',
  resources: [],
  detail: { foo: 'bar', createdAt: 1611889553709 }
}

Answer 1

PreSignUp_SignUp ：您的標准 Cognito 池（用戶名/密碼）注冊

PreSignUp_AdminCreateUser ：當使用管理員方法創建用戶時（要清楚，不是在您創建管理員時，而是當您是管理員時創建不同的用戶）。

PreSignUp_ExternalProvider ：如果您有第三方注冊，例如 Google 或 facebook
