Function Array

net/http/httpjson/io.go:52–57

Array returns an empty JSON array if v is a nil slice, so that it renders as "[]" rather than "null". Otherwise, it returns v.

(v interface{})

// so that it renders as "[]" rather than "null".
// Otherwise, it returns v.
func Array(v interface{}) interface{} {
	if rv := reflect.ValueOf(v); rv.Kind() == reflect.Slice && rv.IsNil() {
		v = []struct{}{}
	}
	return v
}
