According to the docs for ParseForm:

For other HTTP methods, or when the Content-Type is not application/x-www-form-urlencoded, the request Body is not read, and r.PostForm is initialized to a non-nil, empty value.

When you submit a file, the content type will be one of the multipart types.

Based on these docs, I'd try this:

 r.ParseMultipartForm(10<<20)
 data := r.PostForm.Get("body")
 fmt.Println(r.PostForm)
 file, header, err := r.FormFile("file")
