Chromium 中chrome.tabs扩展接口定义c++

一、chrome.tabs

注意：Tabs API 可由 Service Worker 和扩展程序页面使用，但不能由内容脚本使用。

使用 chrome.tabs API 与浏览器的标签页系统进行交互。您可以使用此 API 在浏览器中创建、修改和重新排列标签页。

Tabs API 不仅提供操作和管理标签页的功能，语言，截取屏幕截图，然后与标签页的内容脚本通信。

权限

大多数功能无需任何权限即可使用。例如：创建新标签页、重新加载某个标签页、导航到其他网址等。

开发者在使用 Tabs API 时应注意三种权限。

“标签页”权限

此权限不提供对 chrome.tabs 命名空间的访问权限。相反，授予扩展程序对 4 个扩展调用 tabs.query() 的权限 tabs.Tab 实例上的敏感属性：url、pendingUrl、title 和 favIconUrl。

{"name": "My extension",..."permissions": ["tabs"],...
}

主机权限

借助主机权限，扩展程序可以读取和查询匹配标签页的四个敏感项 tabs.Tab 属性。他们还可以使用以下方法直接与匹配的标签页互动：以tabs.captureVisibleTab()的身份， tabs.executeScript()、tabs.insertCSS()和 tabs.removeCSS()。

{"name": "My extension",..."host_permissions": ["http://*/*","https://*/*"],...
}

“activeTab”权限

activeTab 可向某个扩展程序授予对当前标签页的临时主机权限响应用户调用。与主机权限不同，activeTab 不会触发任何警告。

{"name": "My extension",..."permissions": ["activeTab"],...
}
