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 并使用可出租的运算符...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，现在似乎所有静态创建方法，如 of、from 都应该从 rxjs 导入/observable/ ?

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

我仍然对 5.5 感到困惑，但看起来现在不是导入 throw 而是使用 ErrorObservable.

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');

从这个指南看来它必须是_throw 以避免关键字冲突(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)
