func main() { 
    const input = `{ 
     "kind": "ServiceAccount",

     ] 
    }` 
    type NameStruct struct { 
     Name string `json:"name"` 
    } 
    type Secret struct { 
     Secrets []NameStruct `json:"secrets"` 
    } 

    secret := Secret{} 
    json.Unmarshal([]byte(input), &secret) 
    fmt.Println(secret.Secrets[0].Name) 
}
