php - Symfony @Route 注解 i18n : Is it possible to have a fallback for languages not explicitly declared?

Question

在 Symfony 中使用 @Route 注释我可以执行以下操作:

/**
 * @Route({
 *     "en": "/{_locale}/registration",
 *     "de": "/{_locale}/registrierung",
 * },
 * name="registration",
 * defaults={
 *     "_locale":"%kernel.default_locale%"
 * },
 * requirements={
 *     "_locale":"^[a-z]{2}?$"
 * })
 */
public function defaultAction() { }

英语访问者可以调用www.mysite.com/en/registration，德语访问者可以调用www.mysite.com/de/registrierung。

是否可以为未明确声明的语言声明默认值？这样的路线例如es 或 fr 访问者的工作方式类似于 www.mysite.com/es/reg 或 www.mysite.com/fr/reg?

伪代码:

/**
 * @Route({
 *     "en": "/{_locale}/registration",
 *     "de": "/{_locale}/registrierung",
 *     "_default_": /{_locale}/reg"
 * },
 * name="registration",
 * defaults={
 *     "_locale":"%kernel.default_locale%"
 * },
 * requirements={
 *     "_locale":"^[a-z]{2}?$"
 * })
 */
public function defaultAction() { }

Currently不可能通过一个注释来做到这一点。 但是，您可以创建第二个回退操作。此外，它们可以按 priority 排序。 .

例子

/**
 * @Route({
 *     "en": "/{_locale}/registration",
 *     "de": "/{_locale}/registrierung",
 * },
 * name="registration",
 * defaults={
 *     "_locale":"%kernel.default_locale%"
 * },
 * priority="1",
 * requirements={
 *     "_locale":"^[a-z]{2}?$"
 * })
 */
public function defaultAction() {}

/**
 * @Route("/{_locale}/registration",
 * name="registration_fallback",
 * priority="0",
 * requirements={
 *     "_locale":"^[a-z]{2}?$"
 * })
 */
public function fallbackDefaultAction() {
    $this->defaultAction();
}
