如何通过 REST API 检索页面上的图像 url [英] How to retrieve image url on a page through REST API

问题描述

我正在使用 rest api 来检索 sharepoint online 网站上页面的标题、正文等.问题是当我获取页面的 xml 时，没有对页面上加载的图片的引用.我什至得到了标题，但没有参考图片.

I'm using rest api to retrieve title, main text etc. of pages on a site on sharepoint online. Problem is when I fetch the xml of a page, there is no reference to the picture that is loaded on the page. I even get the caption but no reference to the picture.

这是我获得的 xml 和我使用的 uri 的示例:https://mysite.sharepoint.com/sites/test/_api/web/lists/pages/items(6)

here's an example of the xml I get and the uri I use: https://mysite.sharepoint.com/sites/test/_api/web/lists/pages/items(6)

xml:

推荐答案

似乎无法直接使用 SharePoint REST 检索 Publishing Image 字段，请参阅 这篇文章 了解更多信息.

It does not seem possible to retrieve Publishing Image fields using SharePoint REST directly, refer this post for an additional information.

有一种解决方法，可以使用对 /_api/web/lists/getbytitle('Pages')/items()/FieldValuesAsHtml 端点的单独请求来检索发布字段.

There is a workaround, publishing fields could be retrieved using a separate request to /_api/web/lists/getbytitle('Pages')/items(<item id>)/FieldValuesAsHtml endpoint.

以下示例演示了如何从文章页面检索 PublishingPageImage 属性:

The following example demonstrates how to retrieve PublishingPageImage property from an article page:

/_api/web/lists/getbytitle('Pages')/items(<item id>)/FieldValuesAsHtml?$select=PublishingPageImage
