我在Angular 2中编写了一个observable.我的代码是这样的:

Observable.create(observer => {
    // fetched something from web service
    if (some condition) {
        observer.next('something');
        observer.complete();
    }
    else { // error with no data
        observer.error('something else');
        observer.complete(); // Is this required here? Or can I skip this in case of error() ?
    }
});

我正在使用Angular 5并使用该subscribe()方法订阅了一个observable .我想知道是否只调用unsubscribe()订阅上的方法就足以清理所有内容,或者我是否也应该调用remove()方法？

代码段:

`

// somewhere in a method
this.s1 = someObservable.subscribe((value) => {
     //somecode
 });
// in ngOnDestroy
this.s1.unsubscribe(); // should I also call .remove()

`
