在app.module.ts中导入Meta和Title模块，并在导出中配置它们：

import { BrowserModule, BrowserTransferStateModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { RouterModule } from '@angular/router'; import { Meta, Title } from '@angular/platform-browser';

@NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule.withServerTransition({appId: 'my-app'}), BrowserTransferStateModule, RouterModule.forRoot([ // your routes here ]) ], providers: [], bootstrap: [AppComponent] }) export class AppModule { constructor(private meta: Meta, private title: Title) { this.meta.addTags([ { name: 'description', content: 'My App' }, { name: 'keywords', content: 'Angular, Universal, Example' } ]); this.title.setTitle('My App'); } }

在AppComponent中的ngOnInit()函数中更新标题和meta标签：

import { Component, OnInit } from '@angular/core'; import { Meta, Title } from '@angular/platform-browser';

@Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent implements OnInit { constructor(private meta: Meta, private title: Title) {}

ngOnInit() { this.meta.updateTag({ name: 'description', content: 'New description of the page' }); this.title.setTitle('New Title'); } }

这样就可以更新Angular Universal中的标题和meta标签，使其在页面源代码中正确显示。
