(DEPRECATED) Get schema

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"

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

func getSchema(w io.Writer, projectID, schemaID string) error {
	// projectID := "my-project-id"
	// schemaID := "my-schema"
	ctx := context.Background()
	client, err := pubsub.NewSchemaClient(ctx, projectID)
	if err != nil {
		return fmt.Errorf("pubsub.NewSchemaClient: %w", err)
	}
	defer client.Close()

	// Retrieve the full schema view. If you don't want to retrieve the
	// definition, pass in pubsub.SchemaViewBasic which retrieves
	// just the name and type of the schema.
	s, err := client.Schema(ctx, schemaID, pubsub.SchemaViewFull)
	if err != nil {
		return fmt.Errorf("client.Schema: %w", err)
	}
	fmt.Fprintf(w, "Got schema: %#v\n", s)
	return nil
}
