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 设置说明执行操作。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"

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

func addUsers(projectID, topicID string) error {
	// projectID := "my-project-id"
	// topicID := "my-topic"
	ctx := context.Background()
	client, err := pubsub.NewClient(ctx, projectID)
	if err != nil {
		return fmt.Errorf("pubsub.NewClient: %w", err)
	}
	defer client.Close()

	topic := client.Topic(topicID)
	policy, err := topic.IAM().Policy(ctx)
	if err != nil {
		return fmt.Errorf("Policy: %w", err)
	}
	// Other valid prefixes are "serviceAccount:", "user:"
	// See the documentation for more values.
	policy.Add(iam.AllUsers, iam.Viewer)
	policy.Add("group:[e-mail]", iam.Editor)
	if err := topic.IAM().SetPolicy(ctx, policy); err != nil {
		return fmt.Errorf("SetPolicy: %w", err)
	}
	// NOTE: It may be necessary to retry this operation if IAM policies are
	// being modified concurrently. SetPolicy will return an error if the policy
	// was modified since it was retrieved.
	return nil
}
