Hi I will appreciate your help on this
I get Name and type from struct inside the struct but when the struct is on an slice I do not know how to access the name and type of the fields.
This is my code
package main
import (
“fmt”
“net/url”
“time”
“reflect”
“strings”
“strconv”
)
type TestStruct struct {
Children22 struct {// I can acess this one ( see code)
ID string
Name string
}
Children23 []struct { // this is not struct it is slice of sruct
ID1 string // I would like to access this one
Name1 string
}
Nest struct {
Children []struct { // I would like to get to this one too
ID2 string
Name2 string
}
}
}
func main() {
var t1 TestStruct
t1.InterfaceStruct = &InterfaceStruct{}
main := reflect.ValueOf(&t1)
err := GetField(main)
if err != nil {
fmt.Println("Error lev 1 = ", err)
}
}
func GetField ( f reflect.Value ) error {
if f.Kind() != reflect.Ptr {
fmt.Println("Error not a pointer ")
}
val := f.Elem()
lenght := val.NumField()
for i := 0; i < lenght; i++ {
typefield := val.Type().Field(i)
elementType := val.Type().Field(i).Type
type_filed := val.Type().Field(i).Type.String()
elemKind := elementType.Kind()
fmt.Println("typefield.Name = ", typefield.Name)
fmt.Println("elementType = ", elementType)
fmt.Println("what kind =", elemKind )
if elemKind == reflect.Slice{
fmt.Println("is a Slice")
fmt.Println(" Slice type =", val.Field(i).Addr().Elem().Type() )
// what kind of slice
if strings.Contains(type_filed ,"struct") {
// I do not know how to address the struct inside the slice
}
}
if elemKind == reflect.Struct { // check first for time and URL are Struct
if type_filed != "time.Time" && type_filed != "url.URL" {
fmt.Println("is a struct ")
//pass this to function recursive as reflect.Value
newSt := val.Field(i).Addr() // this works fine
err := GetField(newSt) // recall the func to get the struct
if err != nil {
fmt.Println("Error = ", err)
}
}
}
if elemKind == reflect.Map {
fmt.Println("is a Map")
}
fmt.Println(" ")
}
return nil
}
Thanks in advance
