使用gmail API chrome扩展标记gmail邮件时出现的问题

Issue in tagging gmail mails with gmail API chrome extension

本文关键字：gmail 问题 chrome API 扩展 使用      更新时间：2023-09-26

我正在尝试开发一种功能，在该功能中，所选邮件应该被标记为"通用"标签。这个功能应该在按钮点击时执行，所以对于按钮创建，我使用inboxsdk API，对于标签功能，我使用gmail API来执行按钮点击，但我在执行代码时面临问题。我在标签.js文件中得到以下错误

未捕获的语法错误：意外的标记<

我在下面张贴代码。请检查一下。

任何有相关解决方案的人都将不胜感激。

您似乎根本没有掌握扩展体系结构。

您将index.html声明为后台页面——一个用户无法与之交互的不可见页面。为什么它里面有一个按钮呢？

此外，Chrome扩展中不能有任何类型的内联代码，也不可能重写。您必须将扩展代码放在脚本文件中（因此，应该考虑通过指定scripts数组而不是page来以"新"样式声明背景页。

我怀疑修复这些问题是否会使您的扩展按预期工作（您可能不希望在后台使用此代码），但这会用特定的错误回答您最初的问题。
