在线共享点中的批量休息呼叫

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，但找不到运行这些示例，或者我还不知道如何找到。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 bulk/batch 中寻找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制作从 git 到运行的应用程序，我们将不胜感激。

谢谢。

github项目是插件项目，需要先部署插件项目，然后才能使用。

您可以查看来自 here.

的以下脚本
