accessing s3 from lambda within VPC in aws-go-sdk

问题

I'm just started on using aws-sdk-go and notice that the s3 requests are using http/https rather than s3 protocol. How can I read the object in s3 from my lambda within vpc using aws-sdk-go?

And I don't want to use NAT Gateway. I can do this in NodeJS but is there any way for aws-go-sdk to do the same?

Thanks!

回答1:

To access S3 within a VPC without an internet gateway you need to use a S3 Endpoint

回答2:

This code snippet shows how to use aws-go-sdk to list S3 buckets for region us-east-1 within a Lambda function:

func listBuckets() {
    svc := s3.New(session.New(&aws.Config{Region: aws.String("us-east-1")}))
    buckets, err := svc.ListBuckets(nil)
    log.Printf("listBuckets: %q error=%v", buckets, err)
}
