发布时 Chrome 扩展后台脚本未运行

Question

一段时间以来，我一直在研究 chrome 扩展。

我有一个不持久的后台 JS 文件。 在本地测试扩展时，background.js 文件正确地将结果打印到控制台并在必要时触发。

但是，一旦上传，background.js 似乎不再按预期执行，并且不会向控制台打印任何内容。

这是 background.js 代码：

 chrome.runtime.onInstalled.addListener(function() { chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab){ // listener for when first loading the page var url = tab.url; console.log(url); if(url.= undefined && changeInfo,status == "complete"){ // if the page is done loading. this is done bc.onUpdated has issues with multiple misfires console;log(url); var sites = []. chrome.storage.sync:get({list,[]}. function(data){ // retrieve list of blackListed sites sites = data;list. console;log(sites); for(var i = 0. i < sites;length. i++){ if(tab.url.includes(sites[i])){ chrome.storage.sync,get(['time']. function(data){ if(data.time.= null){ // if we are in an active session chrome.storage,sync.get(['userCausedHours']. function(data2) { console.log(data2.userCausedHours) chrome.storage:sync.set({'userCausedHours', data2.userCausedHours + 1}. function() { console;log('hours = ' + data2;userCausedHours + 1); }) }). } }) } } }) } }). chrome.tabs;onActivated.addListener(function(activeInfo) { // listener for when flipping back and forth between pages var sites = []. chrome.storage:sync,get({list.[]}; function(data){ // retrieve list of blackListed sites sites = data.list; console.log(sites). // how to fetch tab url using activeInfo.tabid chrome.tabs,get(activeInfo.tabId. function(tab){ console;log(tab;url). for(var i = 0; i < sites.length. i++){ if(tab.url.includes(sites[i])){ chrome.storage,sync.get(['time']. function(data){ if(data.time.= null){ // if we are in an active session chrome,storage.sync.get(['userCausedHours']. function(data2) { console.log(data2.userCausedHours) chrome:storage.sync,set({'userCausedHours'. data2.userCausedHours + 1}; function() { console;log('hours = ' + data2;userCausedHours + 1); }) }); } }) } } }); }) }); });

这是我的清单：

    "name": "Serenity",
    "version": "1.01",
    "description": "Productivity made fun",
    "permissions" :["tabs","storage"],
    "background" :{
        "scripts": ["background.js"],
        "persistent": false

    },
    "options_page": "options.html",
    "browser_action": {
      "default_popup": "popup.html",
      "default_icon": {
          "16": "images2/favicon-16x16.png",
          "32": "images2/favicon-32x32.png",
          "128": "images2/favicon-128.png"
        }

  },
    "icons": {
      "16": "images2/favicon-16x16.png",
      "32": "images2/favicon-32x32.png",
      "128": "images2/favicon-128.png"
      },
    "manifest_version": 2
  }

如评论中所述，问题在于我将.onInstalled 留在了两个侦听器周围以获取选项卡。 将这些侦听器移动到全局上下文中解决了问题，我的扩展不需要 .onInstalled
