Php 在ZF2路由器中注入默认值

我目前有一个类似这样的段路由：

/shop/：shopId/

，其中

shopId

没有默认值

只要路由匹配，就会触发Module.php中的代码，这将根据

shopId

进行一些准备，并将其保存在会话中

我的问题是，如果可能的话，在这一点上，将路由的默认值设置为该

shopId

？最终的目标是，从现在起，每次组装URL时都不需要指定

shopId

---

我记得在ZF1中，这种行为是默认的，在组装URL时重用请求中匹配的参数，并且必须明确指定要删除这些参数。现在我需要相同的功能，但配置在

Module.php

级别，而不必重写每个

assemble（）

调用。

选项一：从索引操作

$id = $routeMatch->getParam('id', false);
if (!$id)
   $id = 1; // id was not supplied set default one note this can be added as constant or from db .... 

选项二：在module.config.php中设置路由

'product-view' => array(
                'type'    => 'Literal',
                'options' => array(
                    'route'    => '/product/view',
                    'defaults' => array(
                        'controller'    => 'product-view-controller',
                        'action'        => 'index',
                    ),
                ),
                'may_terminate' => true,
                'child_routes' => array(
                    'default' => array(
                        'type'    => 'Segment',
                        'options' => array(
                            'route'    => '[/:cat][/]',
                            'constraints' => array(
                                'cat'     => '[a-zA-Z][a-zA-Z0-9_-]*',
                            ),
                            'defaults' => array(
                            ),
                        ),
                    ),
                ),
            ),

在您的控制器中：

public function indexAction()
    {
        // get category param
        $categoryParam = $this->params()->fromRoute('cat');
        // if !cat then get random category 
        $categoryParam = ($categoryParam) ? $categoryParam : $this->categories[array_rand($this->categories)];
        $shortList = $this->listingsTable->getListingsByCategory($categoryParam);
        return new ViewModel(array(
            'shortList' => $shortList,
            'categoryParam' => $categoryParam
        ));
    }

选项一：从你的索引

$id = $routeMatch->getParam('id', false);
if (!$id)
   $id = 1; // id was not supplied set default one note this can be added as constant or from db .... 

选项二：在module.config.php中设置路由

                'type'    => 'Literal',

                    'route'    => '/product/view',
                    'defaults' => array(
                        'controller'    => 'product-view-controller',
                        'action'        => 'index',
                    ),
                ),
                'may_terminate' => true,
                'child_routes' => array(
                    'default' => array(
                        'type'    => 'Segment',
                        'options' => array(

        $categoryParam = $this->params()->fromRoute('cat');
        // if !cat then get random category 
        $categoryParam = ($categoryParam) ? $categoryParam : $this->categories[array_rand($this->categories)];
        $shortList = $this->listingsTable->getListingsByCategory($categoryParam);
        return new ViewModel(array(
