Cognito 从预注册 Lambda 触发器发送什么类型的事件

Question

PreSignup我使用以下代码创建了一个与 Cognito Pre-SignUp 触发器一起使用的 Lambda 函数：

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;
}

我宁愿指定事件的类型，而不是设置eventto 。anyfunction PreSignup(event: any)

我尝试像APIGatewayProxyEvent这样指定它：

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

但它不起作用，因为eventCognito 预注册触发器发送的不是一种APIGatewayProxyEvent类型。这是一个什么样的活动？

稍后编辑：

以下是 Cognito PreSignUp 触发器推送的复制/粘贴事件：

{
  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
  }
}

下面是这次推送的另一个 AWS 事件的示例AWS EventBridge（与 Cognito Trigger 推送的事件类似）：

{
  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：您的标准 Cognito 池（用户名/密码）注册

PreSignUp_AdminCreateUser：当使用 admin 方法创建用户时（需要明确的是，不是当您创建管理员时，而是当您作为管理员创建不同的用户时）。

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