Here’s a fixed version of it: http://play.golang.org/p/w2ZcOzGHKR
The biggest fix that was needed is when Unmarshalling an array, that property needs to be an array/slice in the struct as well.
For example:
{ "things": ["a", "b", "c"] }
Would Unmarshal into a:
type Item struct {
Things []string
}
And not into:
type Item struct {
Things string
}
The other thing to watch out for when Unmarshaling is that the types line up exactly. It will fail when Unmarshalling a JSON string representation of a number into an int or float field — "1" needs to Unmarshal into a string, not into an int like we saw with ShippingAdditionalCost int
