Rancher UI 目前的 API 只支持一些常用资源处理，通过访问https://rancher_url/v3/可以查看到具体支持的类型。

    但是对于像ServiceAccount之类的资源，可通过 Rancher UI 代理去访问 K8S 直连 API，接口地址为：rancher_url/k8s/clusters/<集群ID>/api/<API版本>/<资源类型>。

    ServiceAccount可以通过 rancher_url/k8s/clusters/<集群ID>/api/v1/serviceaccounts去查看所有的ServiceAccountList，例如访问：https://rancher_url/k8s/clusters/c-nlbtk/api/v1/serviceaccounts，会返回如下结果：

    1. {
    2.   "kind": "ServiceAccountList",
    3.   "apiVersion": "v1",
    4.   "metadata": {
    5.     "selfLink": "/api/v1/serviceaccounts",
    6.     "resourceVersion": "9972577"
    7.   },
    8.   "items": [
    9.     {
    10.       "metadata": {
    11.         "name": "default",
    12.         "namespace": "cattle-logging",
    13.         "selfLink": "/api/v1/namespaces/cattle-logging/serviceaccounts/default",
    14.         "uid": "f570131c-f3eb-4018-8119-85c1544f5750",
    15.         "resourceVersion": "3531475",
    16.         "creationTimestamp": "2019-10-30T03:24:36Z"
    17.       },
    18.       "secrets": [
    19.         {
    20.           "name": "default-token-w6pjb"
    21.         }
    22.       ]
    23.     },

    您可以通过命名空间筛选 Service Account，例如：https://rancher_url/k8s/clusters/<cluster——id>/api/v1/namespaces/cattle-logging/serviceaccounts，/namespaces/cattle-logging/serviceaccounts是一种过滤方式，表示只返回该命名空间下的 Service Account 列表。

    2.   "kind": "ServiceAccountList",
    3.   "apiVersion": "v1",
    4.   "metadata": {
