将JSON单元素数组转换为字符串

Question

In Go I have to parse this json:

{ 
  "response": [
    {
      "message": [
         "hello world"
      ],
      "misc": [
        {
          "timestamp": [
             "2017-06-28T05:52:39.347Z"
          ],
          "server": [
             "server-0101"
          ]
        }
      ]
    }
  ]
}

I'd like to get an object in Go that doesn't include all the unnecessary arrays of with a single string. The source json will never have more than one string in each array.

So the end result that I'd like to get would be this json:

{ 
  "response": {
    "message": "hello world",
    "misc": {
      "timestamp": "2017-06-28T05:52:39.347Z",
      "server": "server-0101"
    }
  }
}

Or an equivalent object in Go.

Right now I have to use Response[0].Misc[0].Timestamp[0] to access the data which seems weird.

The hard way: Parse the JSON by hand (write our own parser).

The sensible way: Unmarshal via package encoding/json into some Go type matching the JSON or into some generic interface{} and copy the pieces into a different, simpler Go type afterwards.
