    class HttpClient {
}

Performs HTTP requests. This service is available as an injectable class, with methods to perform HTTP requests. Each request method has multiple signatures, and the return type varies based on the signature that is called (mainly the values of observe and responseType).

Note that the responseType options value is a String that identifies the single data type of the response. A single overload version of the method handles each response type. The value of responseType cannot be a union, as the combined signature could imply.

HTTP Request Example

           // GET heroes whose name contains search termsearchHeroes(term: string): observable<Hero[]>{ const params = new HttpParams({fromString: 'name=term'});   return this.httpClient.request('GET', this.heroesUrl, {responseType:'json', params});}

Alternatively, the parameter string can be used without invoking HttpParams by directly joining to the URL.

          this.httpClient.request('GET', this.heroesUrl + '?' + 'name=term', {responseType:'json'});

JSONP Example

          requestJsonp(url, callback = 'callback') { return this.httpClient.jsonp(this.heroesURL, callback);}

PATCH Example

          // PATCH one of the heroes' namepatchHero (id: number, heroName: string): Observable<{}> {const url = `${this.heroesUrl}/${id}`;   // PATCH api/heroes/42 return this.httpClient.patch(url, {name: heroName}, httpOptions)   .pipe(catchError(this.handleError('patchHero')));}
