如果您要添加输入转换器以使用aws_cdk.aws_events.RuleTargetInputProperties类，则需要通过以下示例代码执行此操作：

import * as cdk from 'aws-cdk-lib';
import * as events from 'aws-cdk-lib/aws-events';
import * as targets from 'aws-cdk-lib/aws-events-targets';
import * as iam from 'aws-cdk-lib/aws-iam';

export class MyStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const rule = new events.Rule(this, 'MyRule', {
      schedule: events.Schedule.rate(cdk.Duration.minutes(5)),
    });

    const inputTransformer = {
      inputPathsMap: {
        "state.$": "$.detail.state",
        "account": "$.account",
        "region": "$.region"
      },
      inputTemplate: '{"state": ,"account": "","region": ""}'
    };

    const lambda = new lambda.Function(this, 'MyLambda', {
      runtime: lambda.Runtime.NODEJS_12_X,
      code: lambda.Code.fromAsset('lambda'),
      handler: 'index.handler',
      initialPolicy: [
        new iam.PolicyStatement({
          effect: iam.Effect.ALLOW,
          actions: ['logs:CreateLogGroup', 'logs:CreateLogStream', 'logs:PutLogEvents'],
          resources: ['arn:aws:logs:*:*:*']
        })
      ]
    });

    rule.addTarget(new targets.LambdaFunction(lambda, {
      event: events.RuleTargetInput.fromObject(inputTransformer)
    }));
  }
}
