Can you help me understand why golang unmarshalling is returning a nil result for one decoding attempt of a JSON array, but successful in another? I'm confused about what could be causing this difference. Is it a mistake in the code or is it expected behavior?
package main
import "fmt"
import "encoding/json"
type PublicKey struct {
Id int
Key string
}
type KeysResponse struct {
Collection []PublicKey
}
func main() {
keysBody := []byte(`[{"id": 1,"key": "-"},{"id": 2,"key": "-"},{"id": 3,"key": "-"}]`)
keys := make([]PublicKey,0)
json.Unmarshal(keysBody, &keys)//This works
fmt.Printf("%#v\n", keys)
response := KeysResponse{}
json.Unmarshal(keysBody, &response)//This doesn't work
fmt.Printf("%#v\n", response)
}
