AWS Lambda CDK不会生成SNS主题和订阅

问题描述

我正在使用Typescript和CDK在AWS中生成新的SNS主题和订阅。除了运行编译（npm run build）之外，还需要在代码中采取其他步骤来在AWS中生成这些对象吗？

以下是一些代码段：

import * as sns from '@aws-cdk/aws-sns';
import * as subs from '@aws-cdk/aws-sns-subscriptions';

let lambda = new Function(this,'Function',{
  runtime: Runtime.NODEJS_10_X,handler: "src/handler.handler",code: Code.fromAsset("function"),role: lambdaRole,logRetention: RetentionDays.TWO_WEEKS,logRetentionRole: lambdaRole,timeout: Duration.seconds(10),environment,vpc,vpcsubnets: {
    subnets: subnets
  },securityGroups: [
    new SecurityGroup(this,"SG",{
      vpc,allowAllOutbound: true,description: StackConfiguration.name + "-sg",securityGroupName: StackConfiguration.name + "-sg",})
  ],functionName: StackConfiguration.name,description: `Handler for ${StackConfiguration.name} with version ${StackConfiguration.version}`
});    

const isProd = StackConfiguration.environmentKey === 'production';

const key = new Key(this,"CustomKey");
key.grantEncryptDecrypt(lambda);
const topic = new sns.Topic(this,"outbound-claim-events-lambda-topic",{
  masterKey: key
});

if(isProd) {
  topic.addSubscription(new subs.EmailSubscription('xxxxxxxxx'));
} else {
  topic.addSubscription(new subs.EmailSubscription('xxxxxxxxx'));
}
topic.grantPublish(lambda)

解决方法

在将AWS CLI配置为要部署组件的AWS帐户的同时，您需要运行CDK deploy。
