go言语yaml转map、map遍历的完成-新流派 - 专业行业资讯与产品服务平台

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：完成了base64 编解码、言语yaml转map 、完成和map遍历

func main() { f,言语 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[inte***ce{ }]inte***ce{ }) resultMap := make(map[inte***ce{ }]inte***ce{ }) if err := yaml.Unmarshal(decodeBytes, &resultMap); err != nil {   // error handling  log.Fatalln(err) }// 遍历map 
，此处取metadata.name值 for key,完成 value := range resultMap {   switch key := key.(type) {   case string:   if key == "metadata" {     switch value := value.(type) {     case string:    case map[inte***ce{ }]inte***ce{ }:     for k, v := range value {       switch k.(type) {       case string:        if k == "name" {          fmt.Println("value=", v)        }      }     }    }   }  } }}
