如何在 MS Graph 或 SharePoint REST API 中区分网站页面和 Wiki 页面

Question

我使用新的 SharePoint 在线体验在 SitePages 库中创建了一个 SharePoint 页面。页面已创建，我尝试使用 MS Graph 端点获取页面属性：

https://graph.microsoft.com/v1.0/drives/{drive-id}/root:/site_page.aspx?expand=listItem

我得到的回应：

{
    ...
    "name": "site_page.aspx",
    ...
    "file": {
        "mimeType": "application/xml",
        "hashes": {
            "quickXorHash": ""
        }
    },
    ...
    "listItem": {
        ...
        "id": "4",
        ...
        "contentType": {
            "id": "0x0101009D1CB255DA76424F860D91F20E6C411800020BAE24978F3545AFD24007B325ACF9"
        },

        "fields": {
            "FileLeafRef": "site_page.aspx",
            "Title": "site_page",
            "LinkTitle": "site_page",
            "id": "4",
            "ContentType": "Site Page",
            ...
        }
    }
}

然后我将 Wiki 页面内容添加到此库中以支持我网站中的 Wiki 页面。 我创建了一个新的 Wiki 页面并使用 MS Graph 端点再次获取页面属性：

    https://graph.microsoft.com/v1.0/drives/{drive-id}/root:/wiki_page.aspx?expand=listItem

我得到的回应：

    {
    ...
    "name": "wiki_page.aspx",
    ...
    "file": {
        "mimeType": "application/xml"
    },
    ...
    "listItem": {
        ...
        "id": "5",
        ...
        "contentType": {
            "id": "0x0101009D1CB255DA76424F860D91F20E6C411800020BAE24978F3545AFD24007B325ACF9"
        },

        "fields": {
            "FileLeafRef": "wiki_page.aspx",
            "Title": "wiki_page",
            "LinkTitle": "wiki_page",
            "id": "5",
            "ContentType": "Site Page",
            "WikiField" : "..."
            ...
        }
    }
}

如您所见，这两个项目具有相同的内容类型。这怎么可能？ 唯一的区别是 wiki_page 项目不包含“哈希”属性，但包含“WikiField”属性（存储 wiki 页面内容的位置）。 有没有其他区分页面类型的方法？

你可以试试这个端点：GET /sites/{site-id}/lists/{list-id}/items?expand=fields(select= ContentType)

我的测试结果：

你最好检查一下你的页面类型。

更新：

"fields@odata.context": "https://graph.microsoft.com/v1.0/$metadata#sites('siteid')/lists('63307f0b-bc1c-4372-bfea-6352ed57a0ff')/items('13')/fields/$entity"

                    "ContentType": "Site Page"
                }
