Unmarshal comma-separated string or int values in json to an array

Question

I have a piece of code that collects key/value store into json. Now key value store may contain array as a value, below is the json

{
  "name":"abc",
  "address":"some address value",
  "phonenumber": "\"123123\",\"7897897\",\"45345345\""
}

and I want to unmarshal this to below struct

type myobj struct{
  Name string `json:"name"`
  Address string `json:"address`
  PhoneNumbers []string
}

the phonenumbers field is a comma separated list in json, and I want to unmarshal this to an array of strings, how to I go about this?

Answer 1

You can unmarshal it to a string and then split it.

type myobj struct{
  Name string `json:"name"`
  Address string `json:"address`
  PhoneNumberRaw string `json:"phonenumber"`

  PhoneNumbers []string `json:"-"`
}

// Unmarshal.
var o myobj
json.Unmarshal(yourData, &o)

// Remove the quotes and split the phone number string by comma.
o.PhoneNumbers = strings.Split(strings.ReplaceAll(o.PhoneNumberRaw, `"`, ""), ",")
