sockjs.js:2999
WebSocket connection to

Ursache:
der Controller Pfad wurde nicht richtig aufgerufen
Aufruf als Beispiel: Controller ->Route hier api/articles dann die Action Methode = endpoints
Hier List
Aufruf unter Angular Daten Service
Aufruf aus Angular Service mit:
Falsche API URL https://localhost:44344/api/articles vollständig mit /list
export class ArticleDataService {
private url_Api_Base: string = "https://localhost:44344/api/articles";
resultsLength = 0;
isLoadingResults = true;
isRateLimitReached = false;
constructor(private http: HttpClient) { }
//----< get_Data_List
>----
//*read web-API : entire List
top20
get_Data_List(): Observable<ArticleModel[]> {
return this.http
.get<ArticleModel[]>(this.url_Api_Base)
.pipe(
map((response: ArticleModel[]) => {
return response;
}
)
)
}
//----</ get_Data_List >----
