AWS CDK：如何获取HTTP API Gateway的Integration ID并关联路由

在使用AWS CDK（C#）创建HTTP API Gateway集成后，无需手动查找集成ID，直接通过CfnIntegration的内置属性即可获取，修改代码如下：

创建集成并获取ID #

var cfnIntegration = new CfnIntegration(this, "Integration", new CfnIntegrationProps()
{
   ApiId = cfnAPI.AttrApiId,
   IntegrationType = "AWS_PROXY",
   IntegrationUri = "arn:aws:lambda:us-east-1:123456789:function:TestFunction",
   IntegrationMethod = "POST",
   PayloadFormatVersion = "2.0",
});

// 集成ID可通过 cfnIntegration.AttrIntegrationId 直接引用

关联集成到路由 #

CfnRoute cfnRoute = new CfnRoute(this, "Routes", new CfnRouteProps()
{
  ApiId = cfnAPI.AttrApiId,
  RouteKey = "POST /webhook/digitalChannel",
  Target = $"integrations/{cfnIntegration.AttrIntegrationId}"
});

AttrIntegrationId是AWS CDK为CfnIntegration资源提供的属性，部署阶段会自动解析为实际的集成ID，确保路由与集成正确关联。
