How do I invoke serverless functions on AWS using Go?

Invoking serverless functions on AWS (AWS Lambda) using Go can be efficiently done using the AWS SDK for Go. Below, you will find a simple example of how to set this up and invoke a Lambda function.

This guide demonstrates how to use the AWS SDK for Go to invoke serverless functions with AWS Lambda, simplifying your cloud function workflows.

Here’s an example of invoking a Lambda function in Go:

package main import ( "context" "encoding/json" "github.com/aws/aws-sdk-go/aws" "github.com/aws/aws-sdk-go/aws/session" "github.com/aws/aws-sdk-go/service/lambda" "log" ) func main() { // Create a session to AWS sess := session.Must(session.NewSession(&aws.Config{ Region: aws.String("us-west-2"), })) // Create a Lambda service client svc := lambda.New(sess) // Prepare the payload to pass to the Lambda function payload := map[string]string{ "key": "value", } // Marshal the payload to JSON body, err := json.Marshal(payload) if err != nil { log.Fatalf("failed to marshal request: %v", err) } // Create the invocation input input := &lambda.InvokeInput{ FunctionName: aws.String("myLambdaFunction"), Payload: body, } // Invoke the function result, err := svc.InvokeWithContext(context.Background(), input) if err != nil { log.Fatalf("failed to invoke function: %v", err) } // Log the response log.Printf("Response: %s", string(result.Payload)) }
