Angular SSR localhost: 4000打不开
Angular SSR localhost: 4000 does not open
我有一个 Angular 项目，我想让它与 seo 兼容。我用 Angular Universal 做了这个，但是 localhost: 4000 打不开。当我输入 localhost: 4000 / index.html 时，它会打开并重定向到 localhost: 4000。但是，页面源代码显示为 .所以它没有发生。
我想，"Did I do something wrong?"我问。另一个新的 Angular 项目创建了我在其上创建的相同操作，没有问题。
但是，它在我当前的项目中不起作用。

我尝试了模式："production" 和模式："development" 在 module.exports 在 webpack.server.config.js 中。
没有发生。
可能是什么问题？我在新项目中做同样的操作运行很顺利，但在我当前的项目中却不行。
谢谢。
我试图通过一个一个地删除所有第 3 方包来找到导致问题的包。
我没有从他们那里得到结果。
我的主页上设置了 setInterval。我没有得到结果。
我确信我的 server.ts 和其他配置文件是正确的，因为当我从头开始创建一个新项目时它们工作正常。这就是为什么我没有调用这个问题。
虽然我删除了我主页上的所有代码，但还是打不开
我在 4 天后解决了我的问题。令牌 = localStorage.getItem('token');在我的 Auth.Interceptor 文件中；由于localStorage，我遇到了这些问题。
import { Inject, PLATFORM_ID } from '@angular/core';
import { isPlatformBrowser, isPlatformServer } from '@angular/common';
constructor(@Inject(PLATFORM_ID) private _platformId: Object) { }
if (isPlatformBrowser(this._platformId)) {
token = localStorage.getItem('token');
}
这样就可以访问localhost:4000了。当然localstorage中的所有文件，window，setTimeout，document等命令都报错了。我已经通过上面 'if' 中这些命令的所有行解决了我的整个问题。
谢谢。
