amazon-web-services - how to invoke a request to a network load balancer(nlb) vpc endpoint from a lambda function in aws

Question

I created a service in ECS running a task on many instances for high availability. I created an internal network load balancer and a vpc endpoint, and I registered the service's instances to the nlb's target group. I have an API gateway to receive external requests from the client, and I want to pass these requests to the service and get a response.

I know I can integrate my API Gateway with VPC and attach to the nlb, and it worked. But its not sufficient, and I need to integrate the gateway's endpoint with a lambda to perform more actions on the service responses.

I want to perform a request from the lambda to the vpc/nlb endpoint and get a response from one of the instances, but I cant find anywhere how to do this. Is there a boto3 or any other way to properly invoke a request to the endpoint? like with sagemaker.

Thanks! my aws vpc endpoint description

您可以将 lambda 函数与 vpc 集成。这样，lambda 函数将能够访问 vpc 中的私有资源，包括您的 NLB。

因此，您的 API 网关将与该功能集成，而该功能又将与您的 VPC 集成。该函数将通过 NLB 调用您的服务并将任何响应返回给 API 网关。

没有特殊boto3的功能可以调用您的 NLB。您只需使用常规 python 工具来调用您的 NLB 的 url，例如requests.
