一：概述

介紹Vue axios token 跨域讀取 K8S 1.9版本API 實現。

二：步驟如下

1：創建一個 RBAC賬號[alinux.yaml]

kind: ClusterRoleBinding

apiVersion: rbac.authorization.k8s.io/v1beta1

metadata:

name: alinux

annotations:

rbac.authorization.kubernetes.io/autoupdate: "true"

roleRef:

kind: ClusterRole

name: cluster-admin

apiGroup: rbac.authorization.k8s.io

subjects:

- kind: ServiceAccount

name: alinux

namespace: kube-system

---

apiVersion: v1

kind: ServiceAccount

metadata:

name: alinux

namespace: kube-system

labels:

kubernetes.io/cluster-service: "true"

addonmanager.kubernetes.io/mode: Reconcile

2:查看賬號信息

3：Vue axios 代碼[安裝參見相關文章]

1：安裝axios cnpm install axios --save 阿里源 2：VScode 微軟前端工具 3：postman 模擬請求軟件 1：因訪問第三方API axios 屬于夸域訪問，跨域訪問存在兩種解決方案【服務器器代理，另外一種方式 vue 代理，本文采用vue代理】。 1：代碼<App.vue> import axios from 'axios' export default { name: 'App', mounted() { var url=this.HOST+'api/v1/namespaces' axios.get(url,{ headers: { Authorization: 'Bearer '+'eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJrdWJlcm5ldGVzL3NlcnZpY2VhY2NvdW50Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9uYW1lc3BhY2UiOiJrdWJlLXN5c3RlbSIsImt1YmVybmV0ZXMuaW8vc2VydmljZWFjY291bnQvc2VjcmV0Lm5hbWUiOiJhbGludXgtdG9rZW4tdDY1dDYiLCJrdWJlcm5ldGVzLmlvL3NlcnZpY2VhY2NvdW50L3NlcnZpY2UtYWNjb3VudC5uYW1lIjoiYWxpbnV4Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9zZXJ2aWNlLWFjY291bnQudWlkIjoiMDBjODVkNjEtZDU0Mi0xMWU4LTg5ODgtNTI1NDAwNjY3MGZkIiwic3ViIjoic3lzdGVtOnNlcnZpY2VhY2NvdW50Omt1YmUtc3lzdGVtOmFsaW51eCJ9.FYbkoKd_8SeuAUVDFb6p1RMraNpMfdrowsfeReWdeKm_-YphG32UztVlZvnQSvxlhSVbpGxP7Cjr0azgPbd2C6tIKzCbCulqWwME1h8T33IV02518ZZOaN3jyqqXzWJ6yEFNx9biqffgWWAwOhhVIOer_3DT8lyoDKJRC7JrLxaubliE1jCDYlcag5dmldhkS1U4EH96Px97Z7itzbKtx4M2DfOUXygQkyCG8_VCEhw5eQwQPO1Y9es3EtvMxONj1OO2h9YXuT62Heflz5MsQ4mHKNbuz0Gmz1e1xFV1HAWlQTN3Pz9qzVJ8305IjwVqVrV_-32aLM1GXnrrzKYBssr_nP1FMub0uEjvzOeGJEz6pQ1NLA1Bi0keHINr0yDUXFXE_LUNwS3ZNe4iqVOuwIsKp6pQz-cpnjjTKq5RpvmWlOyHmQ4jKKsAve2ywLZpNoda0S6GgDoSoUP-AvFygEoTbCWqqmTxUS4sgtiLroLEpFxadndjM2leD99wsd9bNDrq65eT2i_0rqa8uE15HORLB6tfKBag5nYp9MrbtKMJqXLqnkosAIy8STqslKuccHPvKKfgsgb4r6O0aPZCK4EdkB3zbG5lAJ3iFj9fTKRl-iFD9_iSEWtavAAbsgGc-it9xyJ0lJ2nwSUM6WXz1rnKcC_TV3pEqXKsE54F6-s' } }) .then(function (response) { console.log(response) }) } }
