Mac*_*ych 9 angular angular-router angular7
在具有“useHash: true”路由器模块配置的 Angular 7 单页应用程序中,我需要生成要在新选项卡中打开的资源的 url。
对于应用程序窗口中的路由,以下代码按预期工作:
this.router.navigate(['foo', 1]);
这意味着,它生成的 url 如下: http://localhost:4200/#/foo/1
虽然使用以下方法时: const url = this.router.createUrlTree(['foo', 1]).toString();
url 是“/foo/1”——没有“#”,所以...
window.open(url, '_blank'); 结果与无效的网址:
我发现的唯一解决方案(黑客)非常残酷:
window.open('#' + url, '_blank');
RouterModule.forRoot(routes, {
useHash: true,
onSameUrlNavigation: 'reload',
}

showItem(item: Item) {
// THIS WORKS AS EXPECTED
this.router.navigate(['item', item.id]);
}
showItemInNewTab(item: Item) {
const url = this.router.createUrlTree(['item', item.id]).toString();
// THIS WORKS BUT ITS A HACK :/
window.open('#' + url, '_blank');
}

显然,Location中的课程@angular/common可以帮助您解决此问题:
import { Location } from '@angular/common';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
constructor(
private _urlSerializer: UrlSerializer,
private _location: Location,
public router: Router) {
}
ngOnInit() {
let tree = this.router.createUrlTree(['/profile']);
// The call to Location.prepareExternalUrl is the key thing here.
console.log(this._location.prepareExternalUrl(this._urlSerializer.serialize(tree)));
// As far as I can tell you don't really need the UrlSerializer.
}
}

当我对此进行测试时,它尊重路由器的useHash设置。
