如何标记（使用 JSON-LD）服务以在 Schema.org 的 LocalBusiness 中显示价格？

Question

当我在 validator 中测试此代码时，我收到属性价格和属性 [=17= 的警告]价格货币。我该如何解决？谢谢。

The property price is not recognized by the schema (e.g. schema.org) for an object of type Service.

<script type="application/ld+json">

在标记中，属性 price 和 priceCurrency 是 located/belong 到 Service object/type，不包含此类属性。这些属性属于 Offer，因此应相应移动它们。

所以只需将它们向上移动一层，在 Service 之外，这样它们就属于 Offer object/type:

<script type="application/ld+json">

    "@type": "LocalBusiness",
    "name" : "Charlotte Property Management",

        "name": "Charlotte Property Management Plans",
        "itemListElement": [
              {
                "@type": "Offer",
                "itemOffered": {
                "@type": "Service",
                  "name": "Silver Plan",
                  "description": " Our Silver Plan is developed for early-stage investors seeking to learn the intricacies of investment property management but with an added protection layer of professional oversight by our experienced team. This plan is perfect for DIY investment enthusiasts."
                },
                  "price": "49",
                  "priceCurrency": "USD"                
              },

                },
