创建 ssr 后，我没有在 app.server.module 中导入任何内容localStorage 和 DOM 窗口有问题，但存在隔离

我遇到了同样的问题。你可以看看这篇文章

https://www.infragistics.com/products/ignite-ui-angular/angular/components/general/framework-and-features/ssr-rendering.html

XMLHttpRequest.send 的问题来自于节点服务器不存在此“对象”这一事实。

我建议您跟踪错误的来源。在我的例子中，它来自 ngx-translate 模块，它试图通过 XMLHttpRequest 获取 JSON 文件。要解决此问题，您必须:

1. 识别从何处调用电话
2. 应用将正确处理请求的拦截器

就我而言，我遵循本教程:https://itnext.io/angular-universal-how-to-add-multi-language-support-68d83f6dfc4d

我添加了拦截器并解决了问题。

希望对你有帮助
