请求参数
| 参数名称 | 类型 | 是否必需 | 参数位置 | 描述 |
|---|---|---|---|---|
| version | String | 是 | URL参数 | API版本号 |
| instanceId | String | 是 | RequestBody参数 | RapidFS 实例 ID |
| filters | List<Filter> | 否 | RequestBody参数 | 条件筛选，见数据类型Filter，多组 filter 之间为条件与关系，多个 value 之间为条件或关系。当前支持字段: • name=cacheNodeId，例如 value=["wn-LVWFONLJei7W-DFfmSUFht1zt", "wn-LVWFONLJei7W-CKVxoBV6soGW"]； • name=ip，例如 value=["192.168.0.1", "192.168.0.2"]； • name=zone，例如 value=["zoneA", "zoneB"]； • name=status，可选枚举值参考 CacheNodeStatus，例如 value=["RUNNING","ADDING"]； • name=cacheDeployGroupName，仅缓存接入类型为 K8S/CCE/AIHC 时支持，例如 value=["test-cache-deploy-group", "test-cdp"] |
| maxKeys | Int | 否 | RequestBody参数 | 返回列表长度，有效范围 [1, 1000]，默认 100 |
| marker | String | 否 | RequestBody参数 | 批量获取列表的查询的起始位置，返回列表按 cacheNodeId 字典序排序，取值为上一次返回的 nextMarker |
返回头域
除公共头域外，无其他特殊头域。
返回参数
| 参数名称 | 类型 | 描述 |
|---|---|---|
| cacheNodeInfos | List<CacheNodeInfo> | CacheNode 信息列表，见数据类型CacheNodeInfo |
| marker | String | 当前查询起始位置 |
| isTruncated | Boolean | true 表示后面还有数据，false 表示已经是最后一页 |
| nextMarker | String | 下一页起始位置，为 null 表示后面没有数据了 |
| maxKeys | Int | 返回的列表元素个数 |
