How to get category by url key in Magento 2?

Here is the code for getting category by category URL key.

The module name is: Magemonkeys_Categorydata

Create a block file: Categoryurl.php

<?php
namespace  Magemonkeys\Categorydata\Block\Index;

class Categoryurl extends \Magento\Framework\View\Element\Template {
{
 protected $filter;
 public function __construct(
      \Magento\Catalog\Block\Product\Context $context,
      \Magento\Catalog\Model\CategoryFactory $categoryFactory,
      array $data = []
    ) {
     parent::__construct($context, $data);
     $this->categoryFactory = $categoryFactory;
 }
 public function getCategory($urlKey)
 {
   $categories = $this->categoryFactory->create()->getCollection()
             ->addAttributeToFilter('url_key', $urlKey)
             ->addAttributeToSelect(['entity_id']);
     return $categories;
 }
}

<?php

namespace Magemonkeys\Categorydata\Block\Index;

class Categoryurl extends \Magento\Framework\View\Element\Template {

{

protected $filter;

public function __construct(

\Magento\Catalog\Block\Product\Context $context,

\Magento\Catalog\Model\CategoryFactory $categoryFactory,

array $data = []

) {

parent::__construct($context, $data);

$this->categoryFactory = $categoryFactory;

}

public function getCategory($urlKey)

{

$categories = $this->categoryFactory->create()->getCollection()

->addAttributeToFilter('url_key', $urlKey)

->addAttributeToSelect(['entity_id']);

return $categories;

}

Now you can get category by using this function getCategory($urlKey) in your phtml file

$urlKey = 'bags';
$category = $this->getCategory($urlKey);
print_r($category->getData());

$urlKey = 'bags';

$category = $this->getCategory($urlKey);

print_r($category->getData());

You can get an array of category data.
