Go에서 구조체 속성에 어떻게 동적으로 액세스하고 수정할 수 있나요?

import (
    "errors"
    "fmt"
    "reflect"
)

func setField(v interface{}, name string, value string) error {
    // Ensure v is a pointer to a struct
    rv := reflect.ValueOf(v)
    if rv.Kind() != reflect.Ptr || rv.Elem().Kind() != reflect.Struct {
        return errors.New("v must be pointer to struct")
    }
    
    rv = rv.Elem() // Dereference pointer

    fv := rv.FieldByName(name) // Lookup field by name
    if !fv.IsValid() {
        return fmt.Errorf("not a field name: %s", name)
    }
    
    if !fv.CanSet() {
        return fmt.Errorf("cannot set field %s", name)
    }

    // Ensure we are setting a string field
    if fv.Kind() != reflect.String {
        return fmt.Errorf("%s is not a string field", name)
    }

    fv.SetString(value) // Set the value
    return nil
}

var config SshConfig
...

err := setField(&config, split[0], strings.Join(split[1:], " "))
if err != nil {
    // Handle error
}
