chrome 提示报错 Error handling response: TypeError: Cannot read properties of undefined (reading 'executeScript')

在 ChatGPT 的帮助下写了一个 Chrome 小插件，结果报错：

chrome 提示报错 Error handling response: TypeError: Cannot read properties of undefined (reading 'executeScript')

解决方法

这是因为 chrome.scripting 不是标准的 Chrome Extension API。从 Chrome 88 开始，chrome.scripting 被引入作为一个实验性 API，用于替代 chrome.tabs.executeScript。

如果你想要使用 chrome.scripting.executeScript，你需要在 manifest.json 中声明以下权限：

"permissions": ["scripting"]

整个的 mainfest.json 就变成了:

{
  "manifest_version": 3,
  "name": "CroWall Image Downloader",
  "version": "1.0",
  "description": "Download all images from a webpage and save them to a folder in Downloads.",
  "permissions": [
    "activeTab",
    "downloads",
    "scripting"
  ],
  "background": {
    "service_worker": "background.js"
  },
  "content_scripts": [
    {
      "matches": ["https://crowall.com/*"],
      "js": ["content.js"]
    }
  ],
  "action": {
    "default_popup": "popup.html",
    "default_icon": {
      "16": "icons/icon.png",
      "48": "icons/icon.png",
      "128": "icons/icon.png"
    }
  }
}

刷新后执行，问题解决。
