租户基础知识

租户是拥有向其分配的职位和公司对象的实体。他们在 Google Cloud Platform 项目和您上传的数据之间构成了一个组织中间层。借助租户,您可以阻止任何数据跨租户共享,从而隔离不同的数据分组,无需设置多个项目。当您为多个客户提供服务,并且不希望在他们之间共享数据,但仍希望使用单个 GCP 项目在内部进行结算和报告时,设置多个租户非常有用。例如:

  • 招聘求职网站提供商为具有多个子公司的组织构建招聘求职网站。
  • 招聘代理机构为多个企业搭建求职者跟踪系统。

每个 Google Cloud Platform 项目都为一个默认租户分配了一个 tenant_id。您也可以在给定项目中创建多个租户而不使用默认值。

各个租户彼此完全隔离。所有 API 只接受单个租户,以避免在单次 API 调用中针对多个租户查询数据。机器学习 (ML) 同样将租户视为离散单元,不会跨租户处理数据。一个项目可以根据需要支持任意数量的租户。

默认租户

Job search v4 和更新的版本都需要一个租户实体。所有项目都被分配有一个默认租户的 tenant_id。如果您不想使用多个租户,可以采用以下选项:

  1. 使用项目的默认租户(推荐)。使用默认租户时,您无需专门引用该租户。您可以使用 projects/{project_id}/jobs/{job_id} 格式,Cloud Talent Solution 后端将假定您正在使用默认租户。

  2. 创建单个租户并使其代替默认租户。如果您自行创建租户,则需要对其进行引用:projects/{project_id}/tenants/{tenant_id}/jobs/{job_id}

默认 tenant_id 对于每个项目都是唯一的,且永远不会被您创建的其他租户所覆盖或替换。您不能对默认租户调用 CRUD 方法。

创建的租户(可选)

您可以选择自行创建租户。CTS 后端为每个职位搜索项目分配了一个默认租户。如果您不想使用多租户来分隔数据,我们建议您使用默认租户。

创建租户

您需要创建一个唯一的 externalId 值并将其分配给新的租户。然后,调用会返回由我们的后端系统分配的唯一 name,此值也会分配给该租户。请务必记录并保存 nameexternalId 值,因为在更新/删除/引用时会用到它们。

以下代码示例将创建一个新租户:

    String projectId = "your-project-id";
    String externalId = "your-external-id";
    createTenant(projectId, externalId);
  }

  // Create Tenant for scoping resources, e.g. companies and jobs.
  public static void createTenant(String projectId, String externalId) throws IOException {
    // Initialize client that will be used to send requests. This client only needs to be created
    // once, and can be reused for multiple requests. After completing all of your requests, call
    // the "close" method on the client to safely clean up any remaining background resources.
    try (TenantServiceClient tenantServiceClient = TenantServiceClient.create()) {
      ProjectName parent = ProjectName.of(projectId);
      Tenant tenant = Tenant.newBuilder().setExternalId(externalId).build();

      CreateTenantRequest request =
          CreateTenantRequest.newBuilder().setParent(parent.toString()).setTenant(tenant).build();

      Tenant response = tenantServiceClient.createTenant(request);
      System.out.println("Created Tenant");
      System.out.format("Name: %s%n", response.getName());
      System.out.format("External ID: %s%n", response.getExternalId());

}
