go语言yaml转map、map遍历的实现

map
本文主要介绍了go语言yaml转map、map遍历的实现,文中通过示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

yaml文件内容

apiVersion: policy/v1beta1
kind: PodSecurityPolicy
metadata:
  name: mysql-snapshot
spec: 
  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=="
