go - Nested Json Array constructs un-marshalling in golang -


i looking @ un-marshalling below json array in golang.

{  "status":{"code":"success"},  "result": {               "total_records":1,               "records": [{                             "last_modified_timestamp":1501209015807,                             "dns_servers":null,                             "is_secured":false,                             "nis_domains":null,                             "storage_platform_resource_key":"e1ee32f9-6576-11e7-82a8-00a098697714",                             "name":"vs1",                             "nis_servers":null,                             "created_timestamp":1501208944094,                             "dns_domains":null,                             "key":"f59dacca-7379-11e7-82a8-00a098697714"                          }]             }  }

i looking extract "key" field here. tried below syntax not able want. 

var dat map[string]interface{}  // unmarshall json body if err := json.unmarshal(body, &dat); err != nil {     fmt.println(err) } svmrecordsmap := dat["result"].(map[string]interface{})["records"] fmt.printf("%+v", svmrecordsmap)  result := (svmrecordsmap["key"].([]interface{})[0]).(map[string]interface{})

any here appreciated. note not looking @ defining corresponding structs , making copy.

thanks!

i think solution can give hint suppose extract keys json without additional type creation.
