go语言如何实现yaml转map、map遍历

这篇文章主要为大家展示了"go语言如何实现yaml转map、map遍历"，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下"go语言如何实现yaml转map、map遍历"这篇文章吧。

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=="
