在 Magento 2 中,可以通过配置锁定来保护配置值,确保它们不被修改。这在多人团队开发环境中非常有用,可以防止一些开发人员无意中修改了其他人的配置。
要使用配置锁定,需要创建一个配置锁定提供程序。以下是一个示例:
<?php namespace Vendor\Module\Model\Config\Provider; use Magento\Framework\App\Config\Value; use Magento\Framework\App\Config\ScopeConfigInterface; use Magento\Framework\App\Config\ValueFactory; use Magento\Framework\Serialize\Serializer\Json; class LockProvider { const XML_PATH_CONFIG_LOCK = 'lock/path/to/config'; /** * @var ValueFactory */ protected $configValueFactory; /** * @var ScopeConfigInterface */ protected $scopeConfig; /** * @var Json */ protected $jsonSerializer; /** * LockProvider constructor. * @param ValueFactory $configValueFactory * @param ScopeConfigInterface $scopeConfig * @param Json $jsonSerializer */ public function __construct( ValueFactory $configValueFactory, ScopeConfigInterface $scopeConfig, Json $jsonSerializer ) { $this->configValueFactory = $configValueFactory; $this->scopeConfig = $scopeConfig; $this->jsonSerializer = $jsonSerializer; } /** * Get the locked config value. * * @return mixed */ public function getLockedConfigValue() { $lockedConfigValue = $this->scopeConfig->getValue(self::XML_PATH_CONFIG_LOCK); if ($lockedConfigValue) { $lockedConfigValue = $this->jsonSerializer->unserialize($lockedConfigValue); } return $lockedConfigValue; } /** * Set the locked config value. * * @param mixed $value * @param string $scope * @param int $scopeId * @return bool */ public function setLockedConfigValue($value, $scope = 'default', $scopeId = 0) { $existingValue = $this->getLockedConfigValue(); if ($existingValue === null) { $configValue = $this->configValueFactory->create(); $configValue->setScope($scope); $configValue->setScopeId($scopeId); $configValue->setPath(self::XML_PATH_CONFIG_LOCK); $configValue->setValue($this->jsonSerializer->serialize($value)); $configValue->save(); return true; } return false; } /** * Delete the locked config value. * * @param string $scope * @param int $scopeId * @return bool */ public function deleteLockedConfigValue($scope = 'default', $scopeId = 0) { $existingValue = $this->getLockedConfigValue(); if ($existingValue !== null) { $configValue = $this->configValueFactory->create(); $configValue->setScope($scope); $configValue->setScopeId($scopeId); $configValue->setPath(self::XML_PATH_CONFIG_LOCK); $configValue->delete(); return true; } return false; } }
