解组不规则的JSON文件

Question

I have a problem with unmarshaling JSON response from one of the APIs. API returns an array of simple objects. It has a structure:

  "dataFields": [
    {
      "key": "Example_key1",
      "value": "Example_value3"
    },
    {
      "key": "Example_key2",
      "value": "Example_value3"
    },
    {
      "key": "Example_key3",
      "value": "Example_value3"
    }
  ]

Generally, there are always 2 strings (possibly a null instead of a string, but this is not a problem).

Unfortunately, recently the provider has introduced a new field that looks like this:

{
  "key": "Example_key4",
  "value": false
}

Now I can not unpack it to a simple unmarshal to the structure I used before:

type DataField struct {
Value string `json:"value,omitempty"`
Key   string `json:"key,omitempty"`
}

Can you suggest to me how you can unpack something like that?

Thank you in advance

The problem was solved using the structure:

type DataField struct {
Value interface{} `json:"value,omitempty"`
Key   string      `json:"key,omitempty"`
}
