Javascript 在特定的网页包构建（2）的情况下，如何将CSS文件中的资源url（）替换为第三方域？

我想以以下方式在CSS中使用url（）：

.someImage {
    background: url(/assets/img/some-image.png);
}

如果我使用的是开发构建（config/webpack.dev.js），我希望它被翻译成

background:url（/assets/img/some image.png）（默认情况下工作时）

但是，如果我使用的是产品构建（config/webpack.prod.js），我希望它被翻译成
background:url(http://some-3rd-party-domain.com/assets/img/some-image.png);

想想
http://some-3rd-party-domain.com
因为它是一个与angular应用服务器完全不同的域

另一件重要的事情是，我不想替换css文件中的所有路径。这意味着我只想在url（）与特定路径匹配时替换它们（在本例中为：/assets/*）

没有深度黑客攻击，这是可能的吗？如果是，如何进行？

在这里，您可以从我的当前配置中找到一些详细信息：

config/webpack.common.js的相关部分
：

谢谢大家!
 我认为，您应该查看关于publicPath的文档：


输出：{
路径：“/home/proj/public/assets”，
publicPath:ENV==“开发”？“/assets/”：“http://some-3rd-party-domain.com/assets/"
}
