Magento2：检查它是前端还是后端？

我想检查它是前端还是后端。
我怎样才能做到这一点？

使用objectManager

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$state =  $objectManager->get('Magento\Framework\App\State');
echo $state->getAreaCode(); //frontend or adminhtml or webapi_rest

有依赖注入

protected $_state;

public function __construct (
    \Magento\Framework\App\State $state
) {
    $this->_state = $state;
}

public function getArea()
{
    return $this->_state->getAreaCode();
}

注意：根据magento2编码标准，请勿直接在文件中使用对象管理器实例

人们已经回答了这个问题。我只是在做的更好。

const AREA_CODE = \Magento\Framework\App\Area::AREA_ADMINHTML;

private $_state;

public function __construct (
    \Magento\Framework\App\State $state
) {
    $this->_state = $state;
}

public function isAdmin()
{
    $areaCode = $this->_state->getAreaCode();
    return $areaCode == self::AREA_CODE;
}

使用以下代码

$objectmanager = \Magento\Framework\App\ObjectManager::getInstance();
$state =  $objectmanager->get('Magento\Framework\App\State');
if($state->getAreaCode() == 'frontend')
  //frontend
else
  //backend

尝试下面的代码检查您是否在管理员区域

function df_is_admin($store = null) {
    /** @var \Magento\Framework\ObjectManagerInterface $om */
    $om = \Magento\Framework\App\ObjectManager::getInstance();
    /** @var \Magento\Framework\App\State $state */
    $state =  $om->get('Magento\Framework\App\State');
    return 'adminhtml' === $state->getAreaCode();
}

 public function isAdmin(){
      return ('adminhtml' == $this->_state->getAreaCode());
 }
