如需向 Logging 进行身份验证，请设置应用默认凭据。 如需了解详情，请参阅为本地开发环境设置身份验证。

import (
	"context"
	"fmt"
	"io"

	"cloud.google.com/go/logging/logadmin"
)

// getSink retrieves the metadata for a Cloud Logging Sink.
func getSink(w io.Writer, projectID, sinkName string) error {
	ctx := context.Background()

	client, err := logadmin.NewClient(ctx, projectID)
	if err != nil {
		return err
	}
	defer client.Close()

	sink, err := client.Sink(ctx, sinkName)
	if err != nil {
		return err
	}
	fmt.Fprintf(w, "%v\n", sink)
	return nil
}
