I am trying to parse json to go lang struck but some how the object is return empty:

Json Object:

`
 "names": [
 
 "David": 
 "id": "100",
 "country": "usa",
 "group": [
 "A1",
 "A2"
 ]
 
 ,
 
 "John": 
 "id": "1",
 "country": "uk",
 "group": [
 "A1",
 "A2"
 ]
 
 
 ]
`

GoLang struct:

type Data struct 
 Names []Names `json:"names"`


type Names struct 
 ID string `json:"id"`
 Country string `json:"country"`
 Group []string `json:"group"`

The issue that array contains 2 element David,John somehow it return empty object as the parser has problem to extract the strings David,John

arrays json go

The struct Data's Names field is wrong. It is a slice of map[string]Names rather []Names.
So just change it to:

Names []map[string]Names `json:"names"`

Check the full runnable code at https://play.golang.org/p/IDU0jANRbBn.

Here you have another idea:

Parsing into a map

type Dictionary map[string]json.RawMessage

// Generate a Diccionary from JSON body
func Generate(body io.Reader) (Dictionary, error) 
 decoder := json.NewDecoder(body)
 err := decoder.Decode(&d)
 return d, err

Use:

d, err = Generate(strings.NewReader(string(jsonHere)))
