How to get current store ID in async controller

Question

I have an AJAX request POSTing data to a controller in my Magento module.

$.ajax({
 url: "/page/section/profile?isAjax=true",
 type: "POST",
 data: "profileId=" + profile.id,
 success: function (result) {}
}); 

Starting at http://my-website/store2 I post to the /profile endpoint, where I'm trying to access the current store ID in the following (simplified) controller code:

use Magento\Framework\App\Action\Context;
use Magento\Framework\App\ResponseInterface;
use Magento\Framework\App\Action\Action;
class Profile extends Action
{
 /**
 * @var \Magento\Store\Model\StoreManagerInterface
 */
 private $storeManager;
 /**
 * Profile constructor
 *
 * @param Context $context
 */
 public function __construct(
 Context $context,
 \Magento\Store\Model\StoreManagerInterface $storeManager
 ) {
 $this->storeManager = $storeManager;
 parent::__construct($context);
 }
 public function execute()
 {
 $storeId = $this->storeManager->getStore()->getId(); // returns 1
 $websiteId = $this->getRequest()->getParam('website', 0); // returns 0
 return [$storeId, $websiteId];
 }
}

however this always returns store ID 1 (default) instead of the expected store ID 2.

I am not currently logged in to Magento admin.

I have tried to obtain this data via e.g. $this->getRequest()->getParam('website'), in the controller, but that doesn't seem to help either.

• fmsthird: which data are you trying to get using the getParam function?
• strangerpixel: @magefms I have tried to get 'website'. This returns 0.
• fmsthird: can you post your controller code
• fmsthird: check updated answer @strangerpixel

Answer 1

You can try like this in your controller:

$this->request()->getParam('website',0);

UPDATE:

use Magento\Framework\App\Action\Context;
use Magento\Framework\App\ResponseInterface;
use Magento\Framework\App\Action\Action;
class Profile extends Action
{
 /**
 * @var \Magento\Framework\App\Request\Http
 */
 protected $request;
 /**
 * Profile constructor
 *
 * @param Context $context
 */
 public function __construct(
 Context $context,
 \Magento\Framework\App\Request\Http $request
 ) {
 $this->request= $request;
 parent::__construct($context);
 }
 public function execute()
 {
 return $this->request->getParam('website',0);
 }
}

• strangerpixel: Unfortunately that still returns 0 for 'website'.
• fmsthird: did you run the upgrade and other required commands?
• fmsthird: how about changing website to store like return $this->request->getParam('store',0); ?
• fmsthird: @strangerpixel I see your code in your post, it return 0 because you are not injecting \Magento\Framework\App\Request\Http $request in your constructor
• strangerpixel: I have tried it locally, it's the same outcome as $this->getRequest(), which returns a \Magento\Framework\App\RequestInterface. To your earlier point, 'store' param is also null. The request object in the controller only gives access to the params I have explicitly posted to it.

Answer 2

It turned out I needed to post data to the appropriate store URL, defined in the block beforehand.

Block:

public function getEndpointWithStoreCode()
{
 return $this->storeManager->getStore()->getBaseUrl(
 \Magento\Framework\UrlInterface::URL_TYPE_WEB,
 true
 ) . "/page/section/profile?isAjax=true";
}

Template:

<script type="text/x-magento-init">
{
 "*": {
 "my_module/js/profile" : {
 "profileEndpoint" : "<?= $block->getEndpointWithStoreCode() ?>"
 }
 }
}

JS:

$.ajax({
 url: config.profileEndpoint,
 type: "POST",
 data: "profileId=" + profile.id,
 success: function (result) {}
});

By POSTing directly to /store2/page/section/profile, the right store scope is locked in.
