是的，Angular Universal可以与本地Express API集成。下面是一个示例解决方法。

首先，创建一个Angular项目：

ng new example-app

然后，进入项目目录并安装Angular Universal：

cd example-app
ng add @nguniversal/express-engine

接下来，创建一个Express API服务器。在项目根目录下创建一个名为server.ts的文件，并在其中编写以下代码：

import * as express from 'express';

const app = express();
const port = 3000;

app.get('/api/example', (req, res) => {
  res.json({ message: 'Hello from API!' });
});

app.listen(port, () => {
  console.log(`API server listening on port ${port}`);
});

然后，在package.json文件中添加一个新的npm脚本，用于启动API服务器：

"scripts": {
  "start:api": "ts-node server.ts"
}

接下来，我们需要修改Angular Universal配置以集成Express API。打开angular.json文件并找到"projects > example-app > architect > server"部分，将其修改为以下内容：

"server": {
  "builder": "@angular-devkit/build-angular:server",
  "options": {
    "outputPath": "dist/example-app-server",
    "main": "src/main.server.ts",
    "tsConfig": "src/tsconfig.server.json"
  },
  "configurations": {
    "production": {
      "fileReplacements": [
        {
          "replace": "src/environments/environment.ts",
          "with": "src/environments/environment.prod.ts"
        }
      ]
    },
    "dev": {
      "fileReplacements": [
        {
          "replace": "src/environments/environment.ts",
          "with": "src/environments/environment.dev.ts"
        }
      ]
    }
  }
}

然后，修改src/main.server.ts文件以将Express API集成到Angular Universal中。替换该文件的内容为以下代码：

import { enableProdMode } from '@angular/core';
import { environment } from './environments/environment';
import { provideModuleMap } from '@nguniversal/module-map-ngfactory-loader';
import { renderModuleFactory } from '@angular/platform-server';
import * as express from 'express';
import { readFileSync } from 'fs';
import { join } from 'path';

const app = express();
const PORT = process.env.PORT || 4000;

let indexHtml: string;

if (environment.production) {
  enableProdMode();
  indexHtml = readFileSync(join('dist', 'example-app', 'browser', 'index.html'), 'utf-8');
} else {
  indexHtml = readFileSync(join('dist', 'example-app', 'browser', 'index.html'), 'utf-8');
}

app.get('*.*', express.static(join('dist', 'example-app', 'browser')));

app.get('*', (req, res) => {
  renderModuleFactory(AppServerModuleNgFactory, {
    document: indexHtml,
    url: req.url,
    extraProviders: [
      provideModuleMap(LAZY_MODULE_MAP)
    ]
  }).then(html => {
    res.status(200).send(html);
  });
});

app.get('/api/example', (req, res) => {
  res.json({ message: 'Hello from API!' });
});

app.listen(PORT, () => {
  console.log(`Server listening on http://localhost:${PORT}`);
});

最后，通过运行以下命令启动Angular Universal服务器和Express API服务器：

npm run build:ssr
npm run serve:ssr
npm run start:api

现在，您可以在浏览器中访问http://localhost:4000来查看Angular Universal与本地Express API集成的效果。
