chrome extension无法获取window对象

背景见上一篇博客修改网页内容的方法
上一篇博客之后,我要修改的网页有一个新改版,然后有个数据存在了window中,我直接在js中使用window.xxx发现无法获取。所以有本文。

搜了一下发现有两种方法,如上,大概就是:

方法1

var script = document.createElement('script');
script.textContent = 'console.log(window);';
(document.head||document.documentElement).appendChild(script);

出现报错:

extensions_version_page.js:6 Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' 'wasm-unsafe-eval' 'inline-speculation-rules' http://localhost:* http://127.0.0.1:*". Either the 'unsafe-inline' keyword, a hash ('sha256-XnQUOdrKm+cYqdkT/ljnkhjaYaitt2Xh3uRQxH/M9z0='), or a nonce ('nonce-...') is required to enable inline execution.

方法2

{

  "version": "1.0",
  "description": "yeshen test",
  "manifest_version": 3,
  "web_accessible_resource": [
    {

        "assets/*",
        "js/contentScript.js"
      ]
    }
  ],
  "content_scripts": [
    {
      "matches": [

        "https://uu.pm.netease.com/v6/issues/*",
        "https://msdk.pm.netease.com/v6/issues/*"
      ],
      "js": [
        "extensions_issue_page.js"
      ],
      "run_at": "document_start"
    },
  ]
}
Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' 'wasm-unsafe-eval' 'inline-speculation-rules' http://localhost:* http://127.0.0.1:*".

报错比较清晰,就是注入的代码和原有代码不在一个域下,无法操作/注入javascript对象。

最后我是这样做的:

我的方法一

从其他页面获取这个数据,在url参数中携带这个信息;

我的方法二

从dom节点中获取第一个元素信息,然后通过网络请求,重新请求需要的数据。
