Parsing a JSON array of JSON objects? - arrays

Question

I am trying to get each JSON object out of a JSON array. I get this data via a HTTP post.
I know what my data will look like:
{
"array":[
{
"entity_title":"University of Phoenix",
"entity_org_name":"CS Club",
"possible_user_name":"Johnny Ive",
"posibble_user_email":"Johhny.Ive#uop.edu",
"user_position_title":"President",
"msg_body_id":4
},
{
"entity_title":"University of San Francisco",
"entity_org_name":"Marketing club",
"possible_user_name":"steve jobs",
"posibble_user_email":"steven.job#uop.edu",
"user_position_title":"Student",
"msg_body_id":5
}
]
}
My example code and my structs look like this:
type MsgCreateUserArray struct {
CreateUser []MsgCreateUserJson `json:"createUserArray"`
}
type MsgCreateUserJson struct {
EntityTitleName string `json:"entity_title_name"`
EntityOrgName string `json:"entity_org_name"`
PossibleUserName string `json:"possible_user_name"`
PossibleUserEmail string `json:"possible_user_email"`
UserPositionTitle string `json:"user_position_title"`
MsgBodyId string `json:"msg_body_id, omitempty"`
}
func parseJson(rw http.ResponseWriter, request *http.Request) {
decodeJson := json.NewDecoder(request.Body)
var msg MsgCreateUserArray
err := decodeJson.Decode(&msg)
if err != nil {
panic(err)
}
log.Println(msg.CreateUser)
}
func main() {
http.HandleFunc("/", parseJson)
http.ListenAndServe(":1337", nil)
}
I am not sure where how to iterate over the JSON array and get the JSON objects and then just work with the JSON objects.

Try this as your structs,
type MsgCreateUserArray struct {
CreateUser []MsgCreateUserJson `json:"array"`
}
type MsgCreateUserJson struct {
EntityOrgName string `json:"entity_org_name"`
EntityTitle string `json:"entity_title"`
MsgBodyID int64 `json:"msg_body_id,omitempty"`
PosibbleUserEmail string `json:"posibble_user_email"`
PossibleUserName string `json:"possible_user_name"`
UserPositionTitle string `json:"user_position_title"`
}
Your entity_title_name is not named correctly, nor is the top level array. After you decode into a MsgCreateUserArray you can iterate over the CreateUser slice to get each MsgCreateUserJson
