Magento 2 REST-API POST V1/guest carts/{cartId}/项目400或404

我正在努力使用REST-API向来宾购物车添加产品。我尝试了不同的方法，结果是404或400个错误

第一种方法来自文档，或者至少是我如何解释它们。第二种方法来自另一个堆栈交换答案。我一定是忽略了什么或是混淆了什么。正确的方法是什么

第一种方法：

第二种方法：

从中我了解到，中间应该有一个额外的步骤，因为您必须使用实际的报价id，而不是

V1/guest carts

返回的掩码。这将流程更改为以下内容

404-未找到路由

您需要在url中使用掩码，在负载中使用id本身。您还可以直接使用该可配置产品的特定简单产品sku，而不是添加可配置产品和选项
