yaml文件内容

apiVersion: policy/v1beta1kind: PodSecurityPolicymetadata: name: mysql-snapshotspec: privileged: false allowPrivilegeEscalation: false volumes: – “*” hostNetwork: false hostIPC: false hostPID: false runAsUser: rule: RunAsAny seLinux: rule: RunAsAny supplementalGroups: rule: RunAsAny fsGroup: rule: RunAsAny

示例代码：实现了base64 编解码、yaml转map、以及map遍历

func main() {f, err := os.Open(“cmd/test.yaml”) if err != nil { log.Fatalln(err) return } input, _ := ioutil.ReadAll(f) // base64 编码 encodeString := base64.StdEncoding.EncodeToString(input)fmt.Println(encodeString)// base64 解码 decodeBytes, err := base64.StdEncoding.DecodeString(encodeString) if err != nil { log.Fatalln(err) }//yaml文件内容转换成map[interface{}]interface{}) resultMap := make(map[interface{}]interface{}) if err := yaml.Unmarshal(decodeBytes, &resultMap); err != nil { // error handling log.Fatalln(err) }// 遍历map ，此处取metadata.name值 for key, value := range resultMap { switch key := key.(type) { case string: if key == “metadata” { switch value := value.(type) { case string: case map[interface{}]interface{}: for k, v := range value { switch k.(type) { case string: if k == “name” { fmt.Println(“value=”, v) } } } } } } }}

结果

encodeString = “YXBpVmVyc2lvbjogcG9saWN5L3YxYmV0YTEKa2luZDogUG9kU2VjdXJpdHlQb2xpY3kKbWV0YWRhdGE6CiAgbmFtZTogbXlzcWwtc25hcHNob3QKc3BlYzogCiAgcHJpdmlsZWdlZDogZmFsc2UKICBhbGxvd1ByaXZpbGVnZUVzY2FsYXRpb246IGZhbHNlCiAgdm9sdW1lczoKICAtICIqIgogIGhvc3ROZXR3b3JrOiBmYWxzZQogIGhvc3RJUEM6IGZhbHNlCiAgaG9zdFBJRDogZmFsc2UKICBydW5Bc1VzZXI6CiAgICBydWxlOiBSdW5Bc0FueQogIHNlTGludXg6CiAgICBydWxlOiBSdW5Bc0FueQogIHN1cHBsZW1lbnRhbEdyb3VwczoKICAgIHJ1bGU6IFJ1bkFzQW55CiAgZnNHcm91cDoKICAgIHJ1bGU6IFJ1bkFzQW55Cg==”
