一个控制器的两条路线或一组动作的两条路线

Question

以下是所需 URL 的方案：

/service/getBalance    should map to CustomerController::getBalance
/service/addBalance    should map to CustomerController::addBalance

/customer/getBalance    should map to CustomerController::getBalance
/customer/addBalance    should map to CustomerController::addBalance

这是一个简单的控制器

<?php

namespace AppBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;

class CustomerController extends Controller {

    /**
     * @Route("/getBalance")
     */
    public function getBalanceAction(Request $request) {

    }

    /**
     * @Route("/addBalance")
     */
    public function addBalanceAction(Request $request) {

    }

} // class CustomerController

试过以下方法。他们都没有工作。

# rounting.yml
v1:
    resource: "@AppBundle/Controller/CustomerController.php"
    prefix:   /service
    type:     annotation

v2:
    resource: "@AppBundle/Controller/CustomerController.php"
    prefix:   /customer
    type:     annotation

加载具有不同前缀的相同资源总是会覆盖上一次出现（最后一次有效）。以下也不会出于相同的原因并具有相同的行为。

# rounting.yml
v1:
    resource: "@AppBundle/Resources/config/routing_customer.yml"
    prefix:   /service

v2:
    resource: "@AppBundle/Resources/config/routing_customer.yml"
    prefix:   /customer


# routing_customer.yml
getBalance:
    path: /getBalance
    defaults : { _controller: "AppBundle:Customer:getBalance" }

addBalance:
    path: /addBalance
    defaults : { _controller: "AppBundle:Customer:addBalance" }

第三个不工作的选项：

# rounting.yml
v1:
    resource: "@AppBundle/Resources/config/routing_v1.yml"
    prefix:   /     # evenr putting /service here instead of inside

v2:
    resource: "@AppBundle/Resources/config/routing_v2.yml"
    prefix:   /     # evenr putting /customer here instead of inside

# routing_v1.yml
getBalance:
    path: /service/getBalance
    defaults : { _controller: "AppBundle:Customer:getBalance" }

addBalance:
    path: /service/addBalance
    defaults : { _controller: "AppBundle:Customer:addBalance" }

# routing_v2.yml
getBalance:
    path: /customer/getBalance
    defaults : { _controller: "AppBundle:Customer:getBalance" }

addBalance:
    path: /customer/addBalance
    defaults : { _controller: "AppBundle:Customer:addBalance" }

我实际上需要路由/和/customer到同一个控制器： /getBalance和/customer/getBalance.

我想为一组方法提供两个前缀。如何在 Symfony 中做到这一点？

我的试验结论、@goto 的回答和@Cerad 的评论：

如果我使用不同的路由名称，上面的最后一个示例可能会起作用。路线名称在整个项目中是唯一的（不仅在文件中唯一）。v1_getBalance和v2_getBalance。

另一种解决方案是使用@goto 描述的自定义加载器。

你可以这样做路由：

     @Route(
          "/{subject}/getBalance",
          requirements={
              "subject": "customer|service"
          }
      )

在 yml 中：

subject_getbalance:
  path:     /{subject}/getBalance
  requirements:
      subject:  customer|service

要求比什么都不安全：它允许您像foo/getBalance在另一个控制器上一样路由另一条路线（因为它不符合要求）

编辑：对于您的特殊情况，因为您也需要 /getBalance 映射到您的路线，您可以这样做：

subject_getbalance:
      path:     /{subject}/getBalance
      default: { _controller: YourBundle:Controller }
      requirements:
          subject:  customer|service
default_getbalance:
      path:     /getBalance
      default: { _controller: YourBundle:Controller, subject: customer }

编辑：最后一个想法是自定义路由加载器（但我从未尝试过）：

class ExtraLoader extends Loader
{
    public function load($resource, $type = null)
    {

       /* ... */

        $prefixes = [ 'default_' =>'','customer_' =>'/customer','service_' =>'/service']

        // prepare a new route
        $path = '/getbalance/{parameter}';
        $defaults = array(
            '_controller' => 'YourBundle:Actiona',
        );
        $requirements = array(
            'parameter' => '\d+',
        );
       foreach($prefixes as $prefixName => $prefixRoute) {
          $route = new Route($prefixRoute . $path, $defaults, $requirements);
          $routes->add($prefixName . 'getBalance', $route);
       }

这将允许您生成 3 条路线：

default_getBalance: /getBalance
customer_getBalance: /customer/getBalance
service_getBalance: /service/getBalance
