aws-cloudformation - AWS Cognito Lambda 触发器不是使用 CDK 创建的

Question

我不明白为什么不创建 Cognito Lambda 触发器。 lambda 已创建，但 AWS 控制台中的触发器列表为空，我必须手动选择它们。

const postConfirmationLambda = new NodejsFunction(
  this,
  'PostConfirmLambda',
  userPoolLambdasProps
);

const postAuthenticationLambda = new NodejsFunction(
  this,
  'PostAuthLambda',
  userPoolLambdasProps
);

usersTable.grantReadWriteData(postConfirmationLambda);
usersTable.grantReadWriteData(postAuthenticationLambda);

const userPool = new UserPool(this, 'UserPool', {
  removalPolicy: RemovalPolicy.DESTROY,
  lambdaTriggers: {
    postConfirmationLambda,
    postAuthenticationLambda,
  },
});

lambdaTriggers 需要一个 UserPoolTriggers 接口(interface)类型:https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_cognito.UserPoolTriggers.html

它看起来像这样:

const userPool = new UserPool(this, 'UserPool', {
  removalPolicy: RemovalPolicy.DESTROY,
  lambdaTriggers: {
    postConfirmation: postConfirmationLambda,
    postAuthentication: postAuthenticationLambda,
  },
});
