我正在使用PHP laravel开发WooCommerce购物车REST Api。以下是此类api的代码段。当我调用add_to_cart函数时，确实将产品添加到购物车中，并且我可以看到在wp_woocommerce_sessions表中存储了一个具有任意会话键值的记录。但是我不知道如何将该记录与特定用户相关联，因此每个用户都有自己的购物车记录，以及当我调用get_cart函数或其他两个函数（即remove_item或clear_cart ）使用特定的用户ID，它只会为我获取与该用户相关的记录，而不是任意记录。现在发生了什么，例如，如果我使用给定的用户ID（例如ID为2）调用add_to_cart函数，则会存储一条记录，然后如果我与另一个用户调用get_cart函数id，例如id为1，我仍然得到了以前存储给用户2的记录。希望我能很好地解释我的问题...
我试图在代码的顶部set_current_user处添加私有函数，因为我认为这可能有助于解决问题，但是，所做的只是更改了< [wp_woocommerce_sessions与用户ID相同，不是一个任意值。另外，我尝试检查woocommerce rest api doc。和wc_cart类文档。并最终尝试通过Google搜索解决方案。
