rxjs 5.5.2中的Observable.throw替换 [英] Observable.throw replacement in rxjs 5.5.2

问题描述

我正在迁移到rxjs@5.5.2并使用可操作的运算符...我还更新了Observable静态方法.我想知道Observable.throw和import 'rxjs/add/observable/throw';的对应物是什么.

I'm migrating to rxjs@5.5.2 and using lettable operators... I also update Observable static methods. I wonder what is the counterpart of Observable.throw and import 'rxjs/add/observable/throw';.

我应该导入丑陋的_throw吗?

import { _throw } from 'rxjs/observable/throw';

或者有更好的方法.老实说，我喜欢Observable上的静态方法，现在看来所有静态创建方法(例如of，from)都应从rxjs/observable/<methodName>导入?

Or there's a better way. Honestly I liked static methods on Observable, and now it seems that all static creating methods like of, from should be imported from rxjs/observable/<methodName> ?

推荐答案

我仍然能解决5.5问题，但现在看起来可以使用 ErrorObservable 而不是导入throw.

I'm still getting my head round 5.5 but it looks like now instead of importing throw use ErrorObservable.

// import { _throw } from 'rxjs/observable/throw';
import { ErrorObservable } from 'rxjs/observable/ErrorObservable';

ErrorObservable.create('error');

从此指南看来，它必须 _throw 避免关键字冲突(视频的其余部分非常适合5.5入门)

From this guide it looks like it has to be _throw to avoid a keyword clash (the rest of the video is good for getting started with 5.5)
