Code sample

Go

Before trying this sample, follow the Go setup instructions in the Pub/Sub quickstart using client libraries. For more information, see the Pub/Sub Go API reference documentation.

To authenticate to Pub/Sub, set up Application Default Credentials. For more information, see Set up authentication for a local development environment.

import (
	"context"
	"fmt"
	"io"
	"time"

	"cloud.google.com/go/pubsub"
)

// createPushNoWrapperSubscription creates a push subscription where messages are delivered in the HTTP body.
func createPushNoWrapperSubscription(w io.Writer, projectID, subID string, topic *pubsub.Topic, endpoint string) error {
	// projectID := "my-project-id"
	// subID := "my-sub"
	// topic of type https://godoc.org/cloud.google.com/go/pubsub#Topic
	// endpoint := "https://my-test-project.appspot.com/push"
	ctx := context.Background()
	client, err := pubsub.NewClient(ctx, projectID)
	if err != nil {
		return fmt.Errorf("pubsub.NewClient: %w", err)
	}
	defer client.Close()

	sub, err := client.CreateSubscription(ctx, subID, pubsub.SubscriptionConfig{
		Topic:       topic,
		AckDeadline: 10 * time.Second,
		PushConfig: pubsub.PushConfig{
			Endpoint: endpoint,
			Wrapper: &pubsub.NoWrapper{
				// Determines if message metadata is added to the HTTP headers of
				// the delivered message.
				WriteMetadata: true,
			},
		},
	})
	if err != nil {
		return fmt.Errorf("CreateSubscription: %w", err)
	}
	fmt.Fprintf(w, "Created push no wrapper subscription: %v\n", sub)
	return nil
