How do I invoke serverless functions on GCP using Go?

Invoking serverless functions on Google Cloud Platform (GCP) using Go is a straightforward process. Google Cloud Functions allows you to run your code in response to events and is ideal for building serverless applications. Below is a simple example of how to invoke a Cloud Function using Go.


    package main

    import (
        "context"
        "fmt"
        "net/http"
        "log"
        
        "cloud.google.com/go/functions/metadata"
    )

    func invokeFunction(ctx context.Context, functionName string) {
        url := fmt.Sprintf("https://REGION-PROJECT_ID.cloudfunctions.net/%s", functionName)
        req, err := http.NewRequest("GET", url, nil)
        if err != nil {
            log.Fatalf("Failed to create request: %v", err)
        }

        client := &http.Client{}
        resp, err := client.Do(req)
        if err != nil {
            log.Fatalf("Failed to invoke function: %v", err)
        }
        defer resp.Body.Close()

        if resp.StatusCode == http.StatusOK {
            log.Println("Function invoked successfully")
        } else {
            log.Printf("Function invocation failed: %s", resp.Status)
        }
    }

    func main() {
        ctx := context.Background()
        invokeFunction(ctx, "myFunction")
    }
