我希望能够在表格中显示这些数据。您需要使用ngFor这样的功能
<table class="table table-striped">
<thead>
<tr>
<th>Title</th>
<th>Id</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let user of users">
<td>{{user.id}}</td>
<td><a routerLink="/detail/{{user.id}}">{{user.title}}</a></td>
</tr>
</tbody>
</table>
</div>
什么不起作用?可能是重复的。你能分享你得到的错误吗?这里有一个有效的stackblitz:。很可能您忘记了将HttpClientModule添加到提供程序。是的,您必须声明变量并分配结果
export class ServiceIncidentComponent implements OnInit {
users: any; //better to have your type
constructor(private service: nowService) {
}
ngOnInit() {
this.service.getAll().subscribe((data) => {
this.users = data;
})
}
}
