      Name: "1.jpg",
    },
    Data: []byte("hello world"),
  },
}
url := "https://httpbin.org/post"
resp, err := http.PostMultipart(url, fields...)

short output:

{
  "files": {
    "img": "hello world"
  },
  "headers": {
    "Content-Type": "multipart/form-data; boundary=54667f9c32b0610e8fd32ffa4db11783c8a34820c6a2a81cd31e48e643db"

	if err != nil {
		panic(err)
	}
	defer func(Body io.ReadCloser) {
		err := Body.Close()
		if err != nil {
			panic(err)
		}
	}(resp.Body)
