손님 인용문을 고객 인용문과 병합 (사용자 정의 된 경우) magento 2 rest api

고객 로그인에 두 항목이 모두있는 경우 장바구니에 2 개의 항목이있는 경우 장바구니를 추가해야합니다 (로그인 전 및 로그인 후).

기본적으로 API 측의 Magento 2는 고객이 로그인 할 때 병합 게스트 카트에 대한 고객 카드 용 API를 제공하지 않습니다.

그러나 손님 카트를 고객 카트로 교체 할 수 있습니다.

API : (/V1/carts/:cartId) 
File : vendor/magento/module-quote/Model/QuoteManagement.php
Function : public function assignCustomer($cartId, $customerId, $storeId)

그러나 Merge cart Live Magento 웹 측 기능을 개발하려면 사용자 정의 API를 작성해야합니다.

사용자 정의 확장에서 "Around"플러그인을 작성해야합니다.
