Question

我一直在尝试在google工作表中实现此功能，但是它仍然在第93行返回“非法形成的xml语法”，最后一行是“？＆gt;”。我附上了没有我个人信息的代码。

我将这段代码粘贴到Google工作表的代码编辑器中，编码为工具 - ＆gt;脚本编辑器，有谁知道我需要改变什么？

如果有人可以帮我弄清楚我在将自定义功能代码实现到google工作表中的错误，我们将不胜感激！

代码开始:(抱歉，我无法弄清楚如何正确输入）

请尝试使用https提供规范网址，而不是使用http。

如HTTPS required for active content

中所述

"Active" content类似脚本，外部样式表和 XmlHttpRequests必须通过HTTPS加载，而不是HTTP 。
