JSON解码未知对象

Question

I'm trying to decode a json response with a struct type. An instance of the object i'm trying to decode looks as follows:

{
  "title": "Some Title",
  "views": 344,
  "profiles": {
      "customField": "somevalue",
      "customField2:" :somevalue"
  }
}

The golang struct is the following:

type Topic struct {
  Title         string   `json:"title"`
  Views         string   `json:"views"`
  Profiles      string   `json:"profiles"`
}

As you can see, the "Profiles" attribute is a string, since the profiles object is unknown, as the fields inside it can be dinamically defined.

I'm trying to decode this with:

json.NewDecoder(response.Body).Decode(result) 

Where result is of type Topic, but isn't working. What type should the "Profiles" attribute be in order to correctly decoding the answer?

Thanks!

Answer 1

Reading the comment it's clear that profiles value could be of any type, for this reason I suggest you to declare the Profiles type as a map[string]interface{}.
Topic becomes:

type Topic struct {
  Title         string   `json:"title"`
  Views         int32   `json:"views"`
  Profiles      map[string]interface{}   `json:"profiles"`
}
