Google chrome extension 防止扩展基于URL列表和通知运行的最佳方法是什么？
我知道如何在清单中包含类似的内容：Google chrome extension 防止扩展基于URL列表和通知运行的最佳方法是什么？,google-chrome-extension,Google Chrome Extension,我知道如何在清单中包含类似的内容： "exclude_matches" : ["*://somesite.somewhere.com/*"], 但是，这对于许多URL似乎并不有用 是否有方法检查外部文件以查看URL或模式是否存在 我是否可以在URL或模式存在时显示通知以提醒用户扩展名不可用？您不能将“排除匹配项”属性绑定到外部文件 如果您需要检查包含URL或模式的文件，我建议使用： 在你的背景页面（或者更好的事件页面）注册一个合适的监听器，例如。 当标签的位置被更新时，让你的背景或事件页面检

使用
当标签的位置被更新时，让您的背景或事件页面通过AJAX请求获取URL列表到您的服务器，并决定是否应该注入内容脚本。（根据您的具体要求，您可以让您的背景页面定期获取更新的文件，而不是在每次选项卡更新时要求更新，以获得更好的性能。）
最后，使用将脚本注入网页（如果需要）
