How to cancel a HTTPRequest in Angular 2?

I know how to reject the request promise only.

return new Promise((resolve, reject) => {     this.currentLoading.set(url, {resolve, reject});      this.http.get(url, {headers: reqHeaders})         .subscribe(             (res) => {                 res = res.json();                  this.currentLoading.delete(url);                 this.cache.set(url, res);                  resolve(res);             }         ); });

You can use the following simple solution:

if ( this.subscription ) {    this.subscription.unsubscribe(); } this.subscription = this.http.get( 'awesomeApi' )  .subscribe((res)=> {   // your awesome code.. })
