问题描述
我希望主要使用此处接受的答案来试验 forkJoin:
I was looking to experiment with a forkJoin mainly using the accepted answer here:
Angular2 Observable.forkJoin of observable variables - ReferenceError: Observable is not定义
我收到上述错误消息,因为 forkJoin 不可用.
I'm getting the above error message as forkJoin isn't available.
有人知道为什么吗?
推荐答案
Angular 6 稍微改变了这一点.forkJoin 已转换为常规函数,而不是:
Angular 6 changes this up a bit. forkJoin has been converted to a regular function so, instead of:
import {Observable} from 'rxjs/Observable';
...
return Observable.forkJoin(
this.http.get('someurl'),
this.http.get('someotherurl'));
使用:
import {forkJoin} from 'rxjs';
...
return forkJoin(
this.http.get('someurl'),
this.http.get('someotherurl'));
