Question

我能够捕获StackOverflow w3schools.com等网站。但是在处理Google页面（Youtube，Drive等）时，它实际上不起作用。在开发阶段使用captureVisibleTab似乎有一定的限制。我是否需要先发布该应用程序才能运行？

这是代码段。

background.js

var triggerCapture = function() {
    chrome.tabs.captureVisibleTab(null, {format:'png'},function(imageURI){
        console.log("captureVisibleTab");   alert(imageURI) // undefined
    }); };

manifest.json

{
  "name": "Queue taker",
  "version": "0.1",
  "description": "Demonstrate screenshot functionality in the chrome.tabs api.",

"background": {
    "persistent": false,
    "page": "screenshot.html"
  },
  "browser_action": {
    "default_icon": "camera.png",
    "default_title": "Queue taker"
  },

  "permissions": "<all_urls>","tabs","activeTab"
  ],

  "content_security_policy":"script-src 'self' https://www.gstatic.com/ https://*.firebaseio.com https://www.googleapis.com; object-src 'self'",

  "manifest_version": 2

错误

：运行tabs.captureVisibleTab时未选中runtime.lastError：由于ExtensionsSettings策略，无法对该页面进行脚本化。在triggerCapture（chrome-extension：//jciafjhdkmanfegbanccjagihhegecpo/background.js：17：17）在chrome-extension：//jciafjhdkmanfegbanccjagihhegecpo/background.js：24：5

chrome.tabs.captureVisibleTab返回未定义
