Marshal of json.RawMessage

Question

Please find the code here http://play.golang.org/p/zdQ14ItNBZ

I am keeping JSON data as RawMessage, but cannot decode it out. I need the containing struct to be Marshall

Answer 1

the methods on json.RawMessage all take a pointer receiver, which is why you're not able to utilize any of them; you don't have a pointer.

This "works" in the sense that it executes, but this is likely not the strategy that you want: http://play.golang.org/p/jYvh8nHata

basically you need this:

type Data struct {
    Name string
    Id   int
    Json *json.RawMessage
}

and then propagate that change through the rest of your program. What... what are you actually trying to do?

Answer 2

jorellis answer is correct for versions of Go before 1.8.

Go 1.8 and newer will correctly handle marshalling of both a pointer and non-pointer json.RawMessage.
