代码示例

Go

在尝试此示例之前，请按照 Pub/Sub 快速入门：使用客户端库中的 Go 设置说明进行操作。 如需了解详情，请参阅 Pub/Sub Go API 参考文档。

如需向 Pub/Sub 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/pubsub"
)

func detachSubscription(w io.Writer, projectID, subName string) error {
	// projectID is the project which contains the topic you manage.
	// This might differ from the project which contains the subscription
	// you wish to detach, which can exist in any GCP project.
	// projectID := "my-project-id"
	// subName := "projects/some-project/subscriptions/my-sub"
	ctx := context.Background()
	client, err := pubsub.NewClient(ctx, projectID)
	if err != nil {
		return fmt.Errorf("pubsub.NewClient: %w", err)
	}
	defer client.Close()

	// Call DetachSubscription, which detaches a subscription from
	// a topic. This can only be done if you have the
	// `pubsub.topics.detachSubscription` role on the topic.
	_, err = client.DetachSubscription(ctx, subName)
	if err != nil {
		return fmt.Errorf("detach subscription failed: %w", err)
	}

	fmt.Fprintf(w, "Detached subscription %s", subName)
	return nil
}
