测试 IAM 权限

测试 IAM 权限。

代码示例

Go

在试用此示例之前，请按照 Data Catalog 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 Data Catalog Go API 参考文档。

如需向 Data Catalog 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"
	"strings"

	datacatalog "cloud.google.com/go/datacatalog/apiv1beta1"
	iampb "google.golang.org/genproto/googleapis/iam/v1"
)

// testIAMPermissions demonstrates a caller probing what permissions they hold on a given taxonomy
// or policy tag resource.
func testIAMPermissions(w io.Writer, resourceID string, permissions []string) error {
	// permissions := []string{"datacatalog.categories.fineGrainedGet"}
	ctx := context.Background()
	policyClient, err := datacatalog.NewPolicyTagManagerClient(ctx)
	if err != nil {
		return fmt.Errorf("datacatalog.NewPolicyTagManagerClient: %w", err)
	}
	defer policyClient.Close()

	req := &iampb.TestIamPermissionsRequest{
		Resource:    resourceID,
		Permissions: permissions,
	}
	resp, err := policyClient.TestIamPermissions(ctx, req)
	if err != nil {
		return fmt.Errorf("TestIamPermissions: %w", err)
	}
	fmt.Fprintf(w, "Testing the permissions on %s, of the %d permissions probed, caller has %d permissions", resourceID, len(permissions), len(resp.Permissions))
	if len(resp.Permissions) > 0 {
		fmt.Fprintf(w, ": %s", strings.Join(resp.Permissions, ", "))
	}
	fmt.Fprintln(w)
	return nil
