如何获取当前选定的发货地址Id magneto 2.3.4

<?php
namespace [Your_Custom_Module]\Observer;

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\Event\Observer;
use Magento\Quote\Model\QuoteRepository;

class GetSelectedShippingAddressId implements ObserverInterface
{
    protected $quoteRepository;

    public function __construct(
        QuoteRepository $quoteRepository
    ) {
        $this->quoteRepository = $quoteRepository;
    }

    public function execute(Observer $observer)
    {
        $quote = $observer->getEvent()->getQuote();
        $shippingAddressId = $quote->getShippingAddress()->getId();
        // 在这里可以使用$shippingAddressId进行后续操作，比如保存到数据库或者进行其他逻辑处理
    }
}
