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=="
