我正在尝试通过按照https://cloud.google.com/resource-manager/docs/performance#partial-responseinstances.aggregatedList设置请求参数来从 Compute API 方法获得特定响应fields

但我越来越400 BAD REQUEST。

有没有我可以参考的样本来获取聚合方法的部分响应？

如果您使用以下 CURL 命令：

curl -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) "https://compute.googleapis.com/compute/v1/projects/[CHANGE-FOR-YOUR-PROJECT-ID]/aggregated/instances?maxResults=1"

您会注意到结果的形式类似于：

{
  "id": "projects/[PROJECT-ID]/aggregated/instances",
  "items": {
    "zones/us-central1-a": {
      "instances": [
        {
          "id": "[INSTANCE-ID]",
          "creationTimestamp": "2020-09-21T06:22:21.604-07:00",
          "name": "instance-1",
          "description": "",
          "tags": {
            "items": [
              "http-server",
              "https-server"
            ],
            "fingerprint": "XXXXXX"
          },
          "machineType": "https://www.googleapis.com/compute/v1/projects/[PROJECT-ID]/zones/us-central1-a/machineTypes/e2-medium",
          "status": "RUNNING",
          "zone": "https://www.googleapis.com/compute/v1/projects/[PROJECT-ID]/zones/us-central1-a",
          "canIpForward": false,
          "networkInterfaces": [
            {
              "network": "https://www.googleapis.com/compute/v1/projects/[PROJECT-ID]/global/networks/default",
              "subnetwork": "https://www.googleapis.com/compute/v1/projects/[PROJECT-ID]/regions/us-central1/subnetworks/[SUBNETWORK_NAME]",
              "networkIP": "10.8.0.13",
              "name": "nic0",
              ... with a lot more fields

如您所见，结果与文档中解释的响应正文略有不同：

{
  "id": string,
  "items": [
    {
      "scopeName": string,
      "instances": [
        {
          "id": string,
          "creationTimestamp": string,
          "name": string,
          "description": string,
          "tags": {
            "items": [
              string
            ],
            "fingerprint": string
          },
          "machineType": string,
          "status": enum,
          "statusMessage": string,
          "zone": string,
          "canIpForward": boolean,
          "networkInterfaces": [
            {
              "network": string,
              "subnetwork": string,
              "networkIP": string,
              "ipv6Address": string,
              "name": string,
              .... with a lot more fields

请注意，如果您比较两个结果，您收到的实际响应在我认为导致您遇到的行为"zones/us-central1-a":的字段之前有一个附加字段。instances:

如果您有兴趣使用部分资源并且只获得响应中的某些特定字段，您只需遵守您共享的文档中解释的语法规则，并在查询参数上相应地使用转义字符。

例如，如果您只对获取id项目的 ' 以及instances'感兴趣name，machineType并且status我使用我的 GCP 项目从 Cloud Shell 测试了以下 curl 命令，并且它可以正常工作：

curl -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) "https://compute.googleapis.com/compute/v1/projects/[PROJECT-ID]/aggregated/instances?fields=id,items/zones%2Finstances(name,machineType,status)"

我看到返回类似于以下内容的地方：

{
  "id": "projects/[PROJECT-ID]/aggregated/instances",
  "items": {
    "zones/us-central1-a": {
      "instances": [
        {
          "name": "instance-1",
          "machineType": "https://www.googleapis.com/compute/v1/projects/[PROJECT-ID]/zones/us-central1-a/machineTypes/e2-medium",
          "status": "RUNNING"
        },
        {
          "name": "instance-2",
          "machineType": "https://www.googleapis.com/compute/v1/projects/[PROJECT-ID]/zones/us-central1-a/machineTypes/e2-medium",
          "status": "TERMINATED"
        }
      ]
    }
  }
}
