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

{"name": "yeshen_extresion","version": "1.0","description": "yeshen test","manifest_version": 3,"web_accessible_resource": [{"resources": ["assets/*","js/contentScript.js"]}],"content_scripts": [{"matches": ["https://innovation.pm.netease.com/v6/issues/*","https://web.pm.netease.com/v6/issues/*","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。
