Edit Question
Title
Body
I'm using JSON to get some values into a variable from an external source. I have a type like this that json.Unmarshal puts values into: type Frame struct { Type string Value map[string]interface{} } var data Frame After unmarshal, I can access a the type by: data.Type but if I try doing something like: if data.Type == "image" { fmt.Printf("%s\n", data.Value.Imagedata) } The compiler complains about no such value data.Value.Imagedata . So my question is, how do I reference properties in Go that I know will be there depending on some condition? Doing this works: type Image struct { Filename string } type Frame struct { Type string Value map[string]interface{} } But that isn't very flexible as I will be receiving different Value s.
