Question

关于 我正在尝试在 Ebay 交易 API 中发布列表。我们可以看到，这里的 Ebay API 文档提到了品牌信息：https://developer.ebay.com/devzone/xml/docs/Reference/eBay/AddItem.html#Input

但仍然给出以下错误。我是否遗漏了 XML 中的任何内容？

Answer 1

来自文档：

“如果使用BrandMPN容器，则需要同时指定Brand和MPN，否则可能会出现错误。”

也就是说，产品必须同时具备品牌和MPN。这应该可以解决您的问题：

<Item>
    <BrandMPN>
        <Brand>Furhaven</Brand>
        <MPN>Some MPN</MPN>
    </BrandMPN>

    ...
