模塊配置ViewJsonStrategy設置沒有在child_route鏈接下工作

Question

我不知道我該如何解釋我的問題。我試圖從擴展abstractrestfulcontroler的模塊中獲取JSON響應。我具有以下模塊配置

文件：module.config.php

return array(
    'controllers' => array(
      'invokables' => array(

）;

現在下面的鏈接工作 - tfw.com.bd/communication/message/user-defined-templates/ OR tfw.com.bd/user-defined-templates-direct-link/

但以下鏈接將無法按預期工作（它表示404控制器未找到） - tfw.com.bd/communication/message/json-request-by-child-route

此處tfw.com.bd指示本地主機。 請注意，我預計輸出爲JSON格式。 還指出，我在這裏使用的所有控制器都是相同的。在某些鏈接/路線中，它不起作用。我無法弄清楚原因。

任何ZF2專家都可以解釋行爲背後的真正原因。

謝謝

Answer 1

最後，我自己得到了這個答案。由於默認的「動作」定義爲「索引」，上述路由配置不起作用。 Zend查找「action」參數，如果找到，則加載該操作。如果未找到，則返回「notFoundAction」。因此，在上述路由器的子路由中定義了「動作」參數。所以，當Zend沒有進入默認的「indexAction」或者進入「notFoundAction」時，它不會進一步發展。

腳註，您需要避免動作參數才能讓「JsonStrategy」按預期工作。如果在路由器中無法避免動作參數，則可以通過重載「AbstractRestfulController」控制器的「onDispatch」方法來修復它。

這裏是我的代碼爲我的作品 -

public function onDispatch(MvcEvent $e){ 
    $routeMatch = $e->getRouteMatch(); 
    if (! $routeMatch) { 
     /** 
     * @todo Determine requirements for when route match is missing. 
     *  Potentially allow pulling directly from request metadata? 
     */ 
     throw new Exception\DomainException(
       'Missing route matches; unsure how to retrieve action'); 
    } 

    $request = $e->getRequest(); 

    // Was an "action" requested? 
    #die('get_class($routeMatch): '.get_class($routeMatch).' @'.__LINE__.': '.__FILE__); 
    $action = $routeMatch->getParam('action', false); 


    if ($action) { 
     // Handle arbitrary methods, ending in Action 
     $method = static::getMethodFromAction($action); 
     if (! method_exists($this, $method)) { 
      if($method=='indexAction'){ 
       $routeMatch->setParam('action', false); 
       return parent::onDispatch($e); 
      } 
      $method = 'notFoundAction'; 
     } 
     $return = $this->$method(); 
     $e->setResult($return); 
     return $return; 
    } 
    return parent::onDispatch($e); 
}
