JSON-LD SiteNavigationElement：子页面的架构无法识别 itemListElement 属性-解网

问：

我有一个问题，我正在尝试使用“SiteNavigationElement”类型方案为我的网页制作 JSON-LD 代码。

但是，当我尝试验证它时。它被拒绝并发出 5 个警告。这让我感到好奇。因为只要我有一个没有子页面的一级 JSON-LD 代码，它就可以很好地验证。

但是当我添加子页面时，它会生成警告。

从波兰语翻译过来，验证者说：

架构无法识别 itemListElement 属性（例如 schema.org）作为 SiteNavigationElement 对象的一部分。

我不知道如何解决这个问题。

基本上，一旦我开始一个子元素，它就会给我一个警告。但我想知道我在那里做错了什么？

            }
        ]
    },

我确实开始了这个职位。我再次设置了上下文。但同样......没有子页面/子页面，效果很好。

您已在不支持此属性的类型中嵌套了一个子元素，例如该属性。若要解决此问题，请使用可用于 SiteNavigationElement 类型的属性。itemListElementSiteNavigationElement

0赞 traynor 9/3/2023 #2

如前所述，标记使用实体，该实体没有 Schema.org 中定义的属性（可与 ItemList 一起使用）。SiteNavigationElementitemListElement

您似乎正在尝试在子父关系中构造多个实体。SiteNavigationElement

有几种方法可以做到这一点。

您可以将 property 替换为 hasPart，这样可以表示子父关系，并通过验证。itemListElement

此外，由于属性属于实体，您可以简单地将其添加到，这在语义上意味着它是两个实体，并允许您同时混合两个实体的属性：itemListElementItemListSiteNavigationElement

            "@type": ["SiteNavigationElement", "ItemList"],
            "position": 4,
            "name": "contact",

它还会模糊两个实体之间的界限，所以我会使用前一种方法。

根据您使用结构化数据的目的，您还可以考虑使用 BreadcrumbList（似乎没有提到子级与父级关系，您只是创建一个页面列表，并且 property 不能与该实体一起使用......hasPart

上一个：在 NASM 中使用 istruc 时：“警告：尝试初始化 BSS 部分 '.bss' 中的内存：忽略 [-w+other]”

下一个：升级 NumPy 时收到警告消息

JSON-LD SiteNavigationElement：子页面的架构无法识别 itemListElement 属性

JSON-LD SiteNavigationElement : itemListElement property was not recognized by the schema for subpages
