在单页上禁用/绕过Magento全页缓存

问题描述：

如何为单个页面禁用或绕过FPC?我不想使用打孔，因为页面上有几个需要动态处理的块，我宁愿修改一个config/class来指定不应该缓存整个页面(类似于签出的行为) ).

How can I disable or bypass FPC for a single page? I don't want to use hole-punching as there are several blocks on the page that I need to be dynamic and I would rather modify one config/class to specify that the entire page should not be cached (similar to the behavior of checkout).

我对FPC的理解是，它不用于会话用户"(已登录，已添加到购物车等).但是，我看到FPC会在用户登录时影响页面.如果禁用FPC，则该页面可以正常工作.

My understanding of FPC was that it was not used for "session users" (logged in, added to cart, etc...). However, I'm seeing FPC affect pages when a user is logged in. If I disable FPC, then the page works as desired.

答

这是为特定控制器禁用FPC的解决方案(也可以扩展到特定操作).

Here is the solution for disabling FPC for a specific controller (could be extended to specific action as well).

首先创建一个观察者以监听controller_action_predispatch事件:

First create an Observer to listen on the controller_action_predispatch event:

public function processPreDispatch(Varien_Event_Observer $observer)
{
    $action = $observer->getEvent()->getControllerAction();

    // Check to see if $action is a Product controller
    if ($action instanceof Mage_Catalog_ProductController) {
        $cache = Mage::app()->getCacheInstance();

        // Tell Magento to 'ban' the use of FPC for this request
        $cache->banUse('full_page');
    }
}

然后将以下内容添加到模块的config.xml文件中. <frontend>部分:

Then add the following to your config.xml file for the module. This goes in the <frontend> section:

<events>
    <controller_action_predispatch>
        <observers>
            <YOUR_UNIQUE_IDENTIFIER>
                <class>YOURMODULE/observer</class>
                <method>processPreDispatch</method>
            </YOUR_UNIQUE_IDENTIFIER>
        </observers>
    </controller_action_predispatch>
</events>

现在，Magento每次都会提供您的页面，并绕过FPC进行请求.

Now Magento will serve up your page every time and bypass FPC for the request.
