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.

	"context"
	"fmt"
	"io"
	"time"

	// matchGlob := "**.txt"
	// minimumObjectCreateTime := "2006-01-02T15:04:05Z"
