How to Create a Plugin with the method afterGetData on the class Magento\Framework\App\Http\Context in magento2?

Question

How can I build this module for our Magento 2 for cache warmer to crawl both desktop and mobile version pages?

We would like to create a plugin with the method afterGetData. On the class Magento\Framework\App\Http\Context

In this method of the plugin, I would like to add a condition by which an additional parameter "device-type" is added to that data.

The afterGetData method may look like this one:

public function afterGetData($subject, $data)
{
 if ([mobile-user-agent-condition]) {
 $data['device-type'] = 'mobile';
 } else {
 $data['device-type'] = 'desktop';
 }
 return $data;
}

Where [mobile-user-agent-condition] is the condition that should return 'true' if the user agent is a mobile user-agent.

1. To create any plugin, you need to put this code into di.xml file :

app\code\Vendor\Extension\etc\di.xml

<config>
 <type name="{ObservedType}">
 <plugin name="{pluginName}" type="{PluginClassName}" sortOrder="1" disabled="false"/>
 </type>
</config>

Where :

type name. A class or interface which the plugin observes.

plugin name. An arbitrary plugin name that identifies a plugin. Also used to merge the configurations for the plugin.

plugin type. The name of a plugin’s class or its virtual type. Use the following naming convention when you specify this element: \Vendor\Extension\Plugin<ClassName>.

2. Then you need to create plugin type file like this one:

   <?php
   namespace Vendor\Extension\Plugin;
   class Yourpluginclassname
   {
    public function afterGetData($subject, $result)
    {
    return '|' . $result . '|';
    }
   }
