我不知道如何解释我的问题。我正试图从我的一个扩展abstractrestfulcontroler的模块中获取JSON响应。我有以下模块配置
文件：module.config.php

现在以下链接正在运行 - tfw.com.bd/communication/message/user-defined-templates/或tfw.com.bd/user-defined-templates-direct-link /
但是以下链接将无法正常工作（它表示未找到404控制器） - tfw.com.bd/communication/message/json-request-by-child-route
这里tfw.com.bd表示localhost。 请注意，我预计输出为JSON格式。 还要注意的是，我在这里使用的是同一个控制器。在某些链接/路由中它不起作用。我无法弄清楚原因。
这里的任何ZF2专家都可以解释行为背后的真正原因。
由于
答案 0 :(得分：1)
最后我自己得到了这个答案。由于默认“action”定义为“index”，上述路由配置不起作用。 Zend寻找“动作”参数，如果找到则加载该动作。如果没有找到，则返回“notFoundAction”。因此，在上面路由器的子路由中定义了“action”参数。因此，当它默认为“indexAction”或“notFoundAction”时，Zend不会再进一步了。
脚注，您需要避免使用action参数来使“JsonStrategy”按预期工作。如果您无法避免路由器中的action参数，可以通过重载“AbstractRestfulController”控制器的“onDispatch”方法来修复它。
以下是我的代码 -
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);
}
