在Angular中,路由解析函数是用来在路由导航之前解析数据的。如果你的路由解析函数不起作用,可以尝试以下解决方法:
resolve
属性中指定了解析函数,并确保函数的命名和路由配置中的一致。const routes: Routes = [
{
path: 'example',
component: ExampleComponent,
resolve: {
data: ExampleResolver
}
}
];
@Injectable()
export class ExampleResolver implements Resolve {
constructor(private exampleService: ExampleService) {}
resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable {
return this.exampleService.getData();
}
}
@Injectable()
export class ExampleResolver implements Resolve {
constructor(private exampleService: ExampleService) {}
resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable {
return this.exampleService.getData();
}
}
@Component({
...
})
export class ExampleComponent implements OnInit {
data: any;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.route.data.subscribe((data: any) => {
this.data = data.data;
});
}
}
通过以上方法,你应该能够解决Angular路由解析函数不起作用的问题。记得检查路由配置、解析函数返回值、注入和订阅过程中的错误。
