Node.js

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 Node.js 设置说明进行操作。如需了解详情，请参阅 Data Catalog Node.js 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 the Google Cloud client library.
const {DataCatalogClient, PolicyTagManagerClient} =
  require('@google-cloud/datacatalog').v1;
const dataCatalog = new DataCatalogClient();
const policyTagManager = new PolicyTagManagerClient();

async function listTaxonomies() {
  /**
   * TODO(developer): Uncomment the following lines before running the sample.
   */
  // const projectId = 'my_project'; // Google Cloud Platform project
  // const location = 'us';

  // Parent project location format is `projects/${projectId}/locations/${location}`
  const parent = dataCatalog.locationPath(projectId, location);

  const request = {
    parent: parent,
  };

  try {
    const [taxonomies] = await policyTagManager.listTaxonomies(request);
    console.log('Taxonomies:');
    taxonomies.forEach(taxonomy => {
      console.log(taxonomy.name);
    });
  } catch (e) {
    console.error(e);
    process.exitCode = 1;
  }
