在线共享点中的批处理休息调用

Question

我正在尝试了解批处理休息调用的工作原理。

我在互联网上找不到任何简单的例子。我从https://github.com/andrewconnell/sp-o365-rest 中找到了示例，但无法运行这些示例，或者我还不知道如何运行。我猜您必须将应用程序部署到共享点站点。

鉴于此，我只是在寻找批量/批量添加列表项和更新列表项的最简单示例。另外，如果有人知道我如何使该 git 中的应用程序运行，将不胜感激。

谢谢。

github项目是一个插件项目，所以需要部署插件项目，然后才能使用。

您可以从here.查看以下脚本

我在this thread的测试结果

    jQuery(document).ready(function () {
