如何在Go中创建AWS Lambda以处理多个事件

Question

I need to implement the AWS Lambda handler to handle AWS S3Events & SNSEvent, any solution?

Already I checked this answer, How to support more than one trigger in AWS Lambda in Golang?

But that's doesn't work for me.

Answer 1

According to this document you could hanlde your custom event. So you can create custom event which includes S3Entity and SNSEntity

type Record struct {
   EventVersion         string           `json:"EventVersion"`
   EventSubscriptionArn string           `json:"EventSubscriptionArn"`
   EventSource          string           `json:"EventSource"`
   SNS                  events.SNSEntity `json:"Sns"`
   S3                   events.S3Entity  `json:"s3"`
}

type Event struct {
    Records []Record `json:"Records"`
}

Then check the EventSource

func handler(event Event) error {
   if len(event.Records) > 0 {
    if event.Records[0].EventSource == "aws:sns" {
       //Do Something
    } else {
       //Do Something
    }
  }

  return nil
}
