subscribe

问题 I am using Akka HTTP cachedHostConnectionPoolHttps pool to send requests as part of Akka Streams Flow: private val requestFlow: Flow[(HttpRequest, HelperClass), Either[Error, String], _] = Http().cachedHostConnectionPoolHttps(BaseUrl).mapAsync(1) { case (Success(HttpResponse(_, _, entity, _)), _) => Unmarshal(entity).to[String].map(response => { Right(response) }) case (Failure(ex), _) => Future(Left(Error(ex))) } For some reason not all request responses are being processed. Some results in

问题 I read about this awesome feature in RXJS which would theoretically allow me to subscribe only for one response, but can't seem to implement it. Instead, I'm getting this error, "Property 'first' does not exist on type 'Observable'." although I am just copy-pasting from existing examples. Here's my code: implementHash( token ){ console.log('trying to implement hash', token); const req = this.http.get('http://localhost:3003/token/' + token ); const sub = req //.first() .subscribe( res =>{ sub

问题 I'm banging my head against the wall with observables. Almost all of the documentation I can find is in the older rxjs syntax. I have an API call which is an observable. I'm calling it elsewhere and subscribing to it - trying to populate a table with the data from this GET request. If I simply console.log my getData function, it logs the subscription rather than my data. I can successfully console.log data within the .subscribe function, but I want to use data outside of .subscribe() . How do

问题 finalize nested observables after the last item is processed. Stackblitz finalize() should be called when the observables complete - all the numbers (11, 12, 13) are output. How should the observables be nested? import { from } from "rxjs"; import { map, finalize } from "rxjs/operators"; //emit (1,2,3) const data = [ { userId: 1, id: 1 }, { userId: 1, id: 2 }, { userId: 1, id: 3 } ]; const source = from(data); //add 10 to each value const example = source.pipe(map(val => add(val.id))); /

问题 So I want to return a value from a subscribe function like this: async obtenerListadoClases(categoria) { var clasesDB = await this.getClases(categoria) .subscribe((data: any) => { clasesDB = data.clasesDB // **Want to return this** console.log(clasesDB,'clasesDB'); // **Getting Value** }) console.log(clasesDB, 'outside'); // **Not Getting Value** return clasesDB; } Also, I want to use this function in another place like this: var listaClases = await this.claseServicio.obtenerListadoClases
