      Google Visualization API Sample

上面的代码在一个 html 文件中为我们生成了一个饼图。当我在浏览器中打开它时它可以工作。让我们调用文件popup.html。

然后我想用以下清单文件使它成为一个 Chrome 扩展：

{
  "name": "History Visualizer",
  "version": "1.0",
  "manifest_version": 2,
  "description": "Helps us analyze history stats in a visual way",
  "browser_action": {
    "default_icon": "icon.png",
    "default_popup": "popup.html"
  }
}

但是当我点击图标按钮时，饼图将无法加载。有人帮我吗？

编辑：检查弹出窗口后的错误消息如下。

由于 Content-Security-Policy，拒绝从“http://www.google.com/jsapi”加载脚本。由于 Content-Security-Policy 拒绝执行内联脚本。

您需要为您的扩展程序指定权限manifest.json才能使用以下资源google.com：

"permissions": [
  "http://*.google.com/"
],

或者，如果这不起作用，请尝试允许您的扩展程序访问所有URL：

"permissions": [
  "<all_urls>"
],

在此处阅读有关权限的更多信息。
