Best Answer

You can try 

$this->getRequest()->getParams();

You can access specific parameter by 

$this->getRequest()->getParam('something');

Post form action

<form id="yotpo-form" action="<?php echo $block->getFormActionUrl() ?>" method="post">
    <?php echo $block->getBlockHtml('formkey')?>
    <input type="hidden" name="form_key" value="<?php echo $this->getFormKey(); ?>" />
    <input id="app_key" type="text" value="<?php echo $block->_config->getAppKey();?>" class="
</form>

Inside your Block

public function getFormActionUrl()
{
    return $this->getUrl('feedback/index/post', ['_secure' => true]);
}

Make sure your Back end controller extend Magento\Backend\App\Action I tested in my controller, those are working fine. if not working there is something went wrong in posting.

Fell free to share your code if not working, hope this helps.
