查看架构定义

您可以查看包含支持架构的数据（例如结构化数据、包含结构化数据的网站数据或包含结构化数据的非结构化数据）的任何数据存储区的架构。

您可以在 Google Cloud 控制台中查看架构，也可以使用 dataStores.schemas.get API 方法查看架构。仅通过 REST API 支持查看网站的架构。

控制台

如需在 Google Cloud 控制台中查看架构，请按以下步骤操作。

1. 如果您正在查看自动生成的架构，请确保已完成数据注入。否则，相应架构可能尚未推出。

2. 在 Google Cloud 控制台中，前往 AI Applications 页面。

   AI Applications

3. 在导航菜单中，点击数据存储区。

4. 在名称列中，点击要查看其架构的数据存储区。

5. 点击架构标签页，查看数据的架构。

REST

如需使用 API 获取架构的定义，请按以下步骤操作：

1. 如果您正在查看自动生成的架构，请确保已完成数据注入。否则，相应架构可能尚未推出。

   如需查看包含网站数据或包含元数据的非结构化数据的数据存储区的架构，请跳至第 3 步以调用 schema.get 方法。

2. 查找数据存储区 ID。如果您已拥有数据存储区 ID，请跳至下一步。

   1. 在 Google Cloud 控制台中，前往 AI Applications 页面，然后在导航菜单中点击数据存储区。

      前往“数据存储区”页面

   2. 点击您的数据存储区的名称。

   3. 在数据存储区的数据页面上，获取数据存储区 ID。

3. 使用 schemas.get API 方法获取架构定义。

   curl -X GET \
   -H "Authorization: Bearer $(gcloud auth print-access-token)" \
   -H "Content-Type: application/json" \
   "https://discoveryengine.googleapis.com/v1/projects/PROJECT_ID/locations/global/collections/default_collection/dataStores/DATA_STORE_ID/schemas/default_schema"
   

   替换以下内容：

   • PROJECT_ID：您的项目的 ID。
   • DATA_STORE_ID：数据存储区的 ID。
