7.3.3. 列出扩展的资源子-Collections

当 Accept 标头包含 detail 参数时，API 会扩展集合表示法，使其包含子集合。

GET /ovirt-engine/api/collection HTTP/1.1
Accept: application/xml; detail=subcollection

GET /ovirt-engine/api/collection HTTP/1.1
Accept: application/xml; detail=subcollection

Copy to Clipboard

Toggle word wrap

这包括使用任一独立 详情 参数的多个子集合请求：

GET /ovirt-engine/api/collection HTTP/1.1
Accept: application/xml; detail=subcollection1; detail=subcollection2

GET /ovirt-engine/api/collection HTTP/1.1
Accept: application/xml; detail=subcollection1; detail=subcollection2

Copy to Clipboard

Toggle word wrap

或者一个将子集合与 + operator 分隔的 detail 参数：

GET /ovirt-engine/api/collection HTTP/1.1
Accept: application/xml; detail=subcollection1+subcollection2+subcollection3

GET /ovirt-engine/api/collection HTTP/1.1
Accept: application/xml; detail=subcollection1+subcollection2+subcollection3

Copy to Clipboard

Toggle word wrap

API 支持下列主要集合的扩展子集合：
