AWS CDK Typescript 问题：预期类型来自属性 'securityGroups'，它在此处声明为类型 'InstanceProps'

Question

我可以在这里做什么？

我收到这个错误：

Type '{ instanceType: ec2.InstanceType; securityGroup: ec2.SecurityGroup; vpc: ec2.IVpc; vpcSubnets: { subnetName: string; }; }' is not assignable to type 'InstanceProps'.
  Object literal may only specify known properties, but 'securityGroup' does not exist in type 'InstanceProps'. Did you mean to write 'securityGroups'?

我的代码：

const dbClusterSecurityGroup = new ec2.SecurityGroup(this, "dbClusterSg", {
      allowAllOutbound: true,
      description: `Project ${projectName} Service database cluster`,
      securityGroupName: `${projectName}Database`,
      vpc,
    });
    dbClusterSecurityGroup.node.applyAspect(new cdk.Tag("Name", "serviceDatabaseCluster"));
    dbClusterSecurityGroup.addIngressRule(
      vpnSG,
      ec2.Port.tcp(postgresDatabasePort),
    );
    dbClusterSecurityGroup.addIngressRule(
      codeBuildProjectSG,
      ec2.Port.tcp(postgresDatabasePort),
    );
if (activeRegion === this.region) {
      const postgresCluster = new rds.DatabaseCluster(this, "dbCluster", {
        backup: {
          preferredWindow: "05:00-06:00",
          retention: cdk.Duration.days(30),
        },
        defaultDatabaseName: postgresDatabaseName,
         engine: [ rds.DatabaseClusterEngine.auroraPostgres ],
         engineVersion: [ rds.AuroraPostgresEngineVersion.VER_13_3 ],
        engineVersion: postgresDatabaseEngineVersion,
        instanceProps: {
          instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.MEDIUM),
          *securityGroup: dbClusterSecurityGroup,*
          vpc,
          vpcSubnets: { subnetName: "data" },
        },

尝试安全组时：dbClusterSecurityGroup，出现错误：

Type 'SecurityGroup' is missing the following properties from type 'ISecurityGroup[]': length, pop, push, concat, and 26 more.
The expected type comes from property 'securityGroups' which is declared here on type 'InstanceProps'

更新我的问题：

securityGroups：[dbClusterSecurityGroup] 这有效但现在出现错误

 engine: [ rds.DatabaseClusterEngine.auroraPostgres ],
 engineVersion: [ rds.AuroraPostgresEngineVersion.VER_13_3 ],

错误是：

TSError: ⨯ Unable to compile TypeScript:
lib/database-stack.ts:120:9 - error TS2739: Type '((props: AuroraPostgresClusterEngineProps) => IClusterEngine)[]' is missing the following properties from type 'IClusterEngine': singleUserRotationApplication, multiUserRotationApplication, supportedLogTypes, bindToCluster, engineType

从检查文档开始：

https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-rds.InstanceProps.html

如您所见，InstanceProps 没有 securityGroup 参数，只有 securityGroups，它接受 array ISecurityGroup 个对象，而不仅仅是您传递的一个 ISecurityGroup。它应该是这样的：

securityGroups: [dbClusterSecurityGroup]
