无法在 RxJs 6 和 Angular 6 中使用 Observable.of
Could not use Observable.of in RxJs 6 and Angular 6
import { Observable, of } from "rxjs";
// And if I try to return like this
return Observable.of(this.purposes);
我收到一条错误消息,指出 属性 'of' 在类型 'typeof Observable'
上不存在
看起来 cartant 的评论是正确的,RxJS upgrade guide 没有具体涵盖该方法,但确实说 "Classes that operate on observables have been replaced by functions"
这似乎意味着所有或大部分 class 方法,如 .of、.throw 等已被函数取代
所以不用
import { Observable, of } from "rxjs";
Observable.of(this.purposes);
做
import { of } from "rxjs";
of(this.purposes);
rxjs 6
import { PreloadingStrategy, Route } from '@angular/router';
import { Observable, of } from 'rxjs';
export class SelectivePreloadingStrategy implements PreloadingStrategy {
preload(route: Route, load: Function): Observable<any> {
return route.data && route.data.preload === false ? of(null) : load();
}
}
为了避免 ,像这样导入它们:
import { Observable } from 'rxjs/Observable';
import { of } from 'rxjs/observable/of';
import { Observable, of } from "rxjs";
// And if I try to return like this
return Observable.of(this.purposes);
