角度5访问包围可见光的场

嗨,角度和字体大师,

https://medium.com/@benlesh/rxjs-observable-interop-with-promises-and-async-await-bebb05306875

在这个例子中,我面临两个问题: -如何访问包含Observable的类的字段

这是一个示例/伪类

import { Observable, Subscription } from 'rxjs/Rx';

export class TestComponent {

    private isRunning: boolean = false;

    construct() {
       this.createObservable()
         .subscribe(
            data => {
               console.log("observable sent: " + data);
            }
            ,error => {
               console.log("observable had an error:");
               console.log(error);
            }
         );

       console.log("If the observable above is asynchronous this will be executed before the observable ends...");

       //for some random event here terminate the observable
       while(Math.floor(Math.random() * 10000) != 6073){ }
       this.isRunning = false;
    }

    private createObservable():Observable<string> {
        this.isRunning = true;
        var obs: Observable<string> = Observable.defer(async function() {
           while(this.isRunning) { //accessing this.isRunning here is an error
             console.log("Observable is still running");
             setTimeout(() => { }, 2000);
             //main logic of the observable goes here...
           }

           //for some event I want to do a
           //observer.next("test string");

           //if an error occurs I want to do a
           //observer.error()

           //after some time... I will need to a
           //observer.complete()
        });

        return obs;
     }

}

接下来的问题是,这是不是一个适当的方法,使异步手动观察? 或者,我是否有正确的心态,认为每个可观察到的都是异步的。 因为当我在这里创建同一个类时,可观察对象/类基于“ import { Observable } from '../../node_modules/rxjs';
顺便说一下,我上面的例子是基于这个 import { Observable } from 'rxjs/Rx';
