我对谷歌应用脚本和融合表非常陌生。我正在为我的公司开发一个 CRM 应用程序，我正在使用谷歌网站、谷歌应用程序脚本和融合表来做到这一点。我还使用 O'Reilly 的“Google Script - Enterprise Application Essentials”一书中的一个示例来构建我的应用程序。我正在使用 Fusion 表作为我的项目的数据库，并运行函数 doOAuth() 以授予每个人对 fusion 表执行操作的权限。（请参阅下面的代码，其中包含我从书中获得的 doOAuth 代码）。该应用程序适用于我对融合表所做的每个命令。我可以读取表格的内容，也可以对其进行搜索，但是在写入新数据或更新表格上的现有数据时，我遇到了一个烦人的问题。我的应用程序上有一些文本框，我在其中插入了一些数据，并且这些数据被写入表中，到目前为止没有问题，当我向这些文本框添加常用文本时，我在更新数据或将数据插入融合表时没有问题。但是，当我向这些文本框中添加任何特殊字符时，例如：á、ã、à、ä、é、õ、í 等，我会收到一条消息，告诉我需要进行授权才能执行该过程。但是我已经授权了。好像授权丢失了。即使我再次运行 doOAuth() 函数，也不会授予权限。insertFusionObj() 和 writeFusionObj() 函数（在下面的代码中列出）在它们的参数是特殊字符时似乎有问题。我不知道这是功能问题还是融合表插入和更新问题。如果有人可以帮助我解决这个问题，我将不胜感激，
我期待着一些帮助。最好的问候拉斐尔·塞蒂·诺盖拉
