}示例2: login
/**
* login on Relution
* @link [relution-sdk](https://github.com/relution-io/relution-sdk)
*/
login(serverModel: ServerModelRc, force?: boolean): Observable<{ user: Relution.security.User }> {
Relution.init({
serverUrl: serverModel.serverUrl,
application: 'studio'
});
if (!force) {
let currentUser: Relution.security.User = Relution.security.getCurrentUser();
if (currentUser) {
return Observable.create((observer: any) => {
observer.next({
user: currentUser
});
observer.complete();
});
}
}

userName: serverModel.userName,
password: serverModel.password
}, serverModel));
}示例3: Promise
import { Observable } from '@reactivex/rxjs';
/*
var clicks = Observable.interval(1000);
var interval = Observable.interval(200);
var buffered = interval.buffer(clicks);
buffered.subscribe(x => console.log(x));
*/
/*
var clicks = Observable.interval(200);
var buffered = clicks.bufferWhen(() =>
Observable.interval(1000)
);
buffered.subscribe(x => console.log(x));
*/
let update$ = Observable.interval(200);
let init$ = Observable.fromPromise(new Promise((resolve, reject) => resolve('hi')));
update$.bufferWhen(() => init$)
.subscribe(x => console.log(x));
