警告 "image" 和 "logo" 有错误的值

Question

我已将 Schema.org 添加到我的博客列表中 JSON-LD:

{
    "@context": "http://schema.org",
    "@type": "BlogPosting",
    "headline": "Fixer la navigation Off-Canvas sur Foundation",
    "image": "https://stephane-richin.s3-eu-central-1.amazonaws.com/S/foundation-website.jpg",
    "author": "Stéphane Richin",
    "datePublished": "2015-02-03",
    "dateModified": "2015-02-03",
    "publisher": {
        "@type": "Organization",
        "name": "Stéphane Richin",
        "url": "http://stephane-richin.fr",
        "logo" : "http://stephane-richin.fr/images/logo/logo-stephane-richin.svg"
    },
    "mainEntityOfPage": "True"
}

但是，我在 image 和 logo 上有 2 个警告：

image.itemtype has wrong value

logo.itemtype has wrong value

您知道为什么图片和徽标的值有误吗？

看起来为了通过结构化数据测试工具，您需要使用 ImageObject 作为 required 属性 of image 并且publisher.logo.

来自他们的documentation：

image - ImageObject, required

您的最终代码将如下所示：

{
    "@context":"http://schema.org",
    "@type":"BlogPosting",
    "headline":"Fixer la navigation Off-Canvas sur Foundation",
    "image": {
      "@type": "ImageObject",
      "url": "https://google.com/thumbnail1.jpg",
      "height": 800,
      "width": 800
    },
    "author": {
      "@type": "Person",
      "name": "Stéphane Richin"
    },
    "datePublished":"2015-02-03",
    "dateModified":"2015-02-03",
    "publisher": {
        "@type":"Organization",
        "name":"Stéphane Richin",
        "url":"http://stephane-richin.fr",
        "logo": {
          "@type": "ImageObject",
          "url": "https://google.com/logo.jpg",
          "width": 600,
          "height": 60
        }
    },
    "mainEntityOfPage": "True"
}

我也修改了一下，承认作者是Person schema。
