zend-framework - 曾: parameter collision

Question

我想知道为什么从来没有人问过这个问题。

Controller 类中的每个 zend Action 函数都有 3 个参数，即“模块”、“ Controller ”和“ Action ”。

当我从表单或 url 中获取名为“action”的参数时会发生什么，例如 "?action=edit"？

我对其进行了测试: Action 从路由器中保存其值(value)，而不是“编辑”。

public function someAction() {
    $params = $this->getRequest()->getParams();
...

如果必须，我如何传递名为“action”的参数？

提前致谢。

默认路由是Zend_Controller_Router_Route_Module它使用模块、 Controller 和操作的默认键:

protected $_moduleKey     = 'module';
protected $_controllerKey = 'controller';
protected $_actionKey     = 'action';

// ...

/**
 * Set request keys based on values in request object
 *
 * @return void
 */
protected function _setRequestKeys()
{
    if (null !== $this->_request) {
        $this->_moduleKey     = $this->_request->getModuleKey();
        $this->_controllerKey = $this->_request->getControllerKey();
        $this->_actionKey     = $this->_request->getActionKey();
    }

    if (null !== $this->_dispatcher) {
        $this->_defaults += array(
            $this->_controllerKey => $this->_dispatcher->getDefaultControllerName(),
            $this->_actionKey     => $this->_dispatcher->getDefaultAction(),
            $this->_moduleKey     => $this->_dispatcher->getDefaultModule()
        );
    }

    $this->_keysSet = true;
}

/**
 * Matches a user submitted path. Assigns and returns an array of variables
 * on a successful match.
 *
 * If a request object is registered, it uses its setModuleName(),
 * setControllerName(), and setActionName() accessors to set those values.
 * Always returns the values as an array.
 *
 * @param string $path Path used to match against this routing map
 * @return array An array of assigned values or a false on a mismatch
 */
public function match($path, $partial = false)
{
    $this->_setRequestKeys();

    $values = array();
    $params = array();

    if (!$partial) {
        $path = trim($path, self::URI_DELIMITER);
    } else {
        $matchedPath = $path;
    }

    if ($path != '') {
        $path = explode(self::URI_DELIMITER, $path);

        if ($this->_dispatcher && $this->_dispatcher->isValidModule($path[0])) {
            $values[$this->_moduleKey] = array_shift($path);
            $this->_moduleValid = true;
        }

        if (count($path) && !empty($path[0])) {
            $values[$this->_controllerKey] = array_shift($path);
        }

        if (count($path) && !empty($path[0])) {
            $values[$this->_actionKey] = array_shift($path);
        }

        if ($numSegs = count($path)) {
            for ($i = 0; $i < $numSegs; $i = $i + 2) {
                $key = urldecode($path[$i]);
                $val = isset($path[$i + 1]) ? urldecode($path[$i + 1]) : null;
                $params[$key] = (isset($params[$key]) ? (array_merge((array) $params[$key], array($val))): $val);
            }
        }
    }

    if ($partial) {
        $this->setMatchedPath($matchedPath);
    }

    $this->_values = $values + $params;

    return $this->_values + $this->_defaults;
}

可以看到，默认模块路由有默认的 mvc 参数键，但是，如果请求对象存在，它将使用请求对象设置的键，我们可以修改这些键。

例如在您的 Bootstrap 中:

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initRequestKeys()
    {
        $this->bootstrap('frontcontroller');
        $frontController = $this->getResource('frontcontroller');
        /* @var $frontController Zend_Controller_Front */

        $request = new Zend_Controller_Request_Http();

        // change action key
        $request->setActionKey("new_action_key");

        // change module
        $request->setModuleKey("new_module_key");

        // change controller
        $request->setControllerKey("new_controller_key");


        // don't forget to set the configured request
        // object to the front controller
        $frontController->setRequest($request);
    }
}

现在您可以将模块、 Controller 和操作用作 $_GET参数。
