How to parse an array of arrays of structures in Golang?

Question

go

I have a structure like this:

type PhotoFaceResp struct {
  Traits map[string][]string `json:"traits"`
  Probability float32 `json:"probability"`
}

I am making a request to some server, the response is JSON from arrays of arrays of such structures. I am trying to serialize it like this:

coreResp := make([][]PhotoFaceResp, 0, 0)

  err := json.Unmarshal(body, &coreResp)

  if err != nil {
    panic(err)
  }

The problem is that when I try to iterate over coreResp afterwards, GoLand tells me that my [][]PhotoFaceResp iterates over ints when iterating over it.

Those:

for face := range coreResp{
    // Тут face - int, а не []coreResp
}

What am I doing wrong and how to do it right?

Answer 1

Do it right like this:

for _, face := range coreResp{
    ...
}

An array iterator returns two values. The index of the element and the element itself. You take the index, because you have it int.
