为什么我会收到“加载扩展失败‘content_security_policy’的值无效”？

问题描述

我正在尝试创建一个 chrome 扩展。我的清单文件是

{
    "name": "Alert-Beep","action": {},"manifest_version": 3,"version": "0.1","description": "Beeps if alert() is called","content_security_policy": "script-src 'self'; object-src 'self'","permissions": [
    "activeTab","scripting"
    ],"content_scripts": [
    {
        "matches": ["https://*.com/*"],"js": ["alert-beep.js"],"run_at": "document_start"
    }
    ]
}

加载扩展失败并显示消息

Failed to load extension
File
~\alert-beep
Error
Invalid value for 'content_security_policy'.
Could not load manifest.

我做错了什么？

解决方法

我已经研究了 CSP 以获取 chrome 扩展（转到 here 以了解有关 manifest v3 的更多信息）。

使用

"content_security_policy": {
  "extension_pages": "script-src 'self'; object-src 'self'"
}

,

一个对我有帮助的附加示例

清单 v3

"content_security_policy": {
    "extension_pages": "script-src 'self'; object-src 'self'; script-src-elem 'self' 'unsafe-inline' https://music.yandex.ru/;"
}
