Comment puis-je définir dynamiquement les propriétés de structure dans Go à l'aide de Reflection ?

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

// setField sets field of v with given name to given value.
func setField(v interface{}, name string, value string) error {
    // v must be 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")
    }

    // Dereference pointer
    rv = rv.Elem()

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

    // Field must be exported
    if !fv.CanSet() {
        return fmt.Errorf("cannot set field %s", name)
    }

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

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

var config SshConfig

...

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