1472 * ### HTTP Request Example
1473 *
1474 * ```
1475 * // GET heroes whose name contains search term
1476 * searchHeroes(term: string): observable<Hero[]>{
1477 *
1478 * const params = new HttpParams({fromString: 'name=term'});
1479 * return this.httpClient.request('GET', this.heroesUrl, {responseType:'json', params});
1480 * }
1481 * ```
1482 *
1483 * Alternatively, the parameter string can be used without invoking HttpParams
1484 * by directly joining to the URL.
1485 * ```
1486 * this.httpClient.request('GET', this.heroesUrl + '?' + 'name=term', {responseType:'json'});
1487 * ```
1488 *
1489 *
1490 * ### JSONP Example
1491 * ```
1492 * requestJsonp(url, callback = 'callback') {
1493 * return this.httpClient.jsonp(this.heroesURL, callback);
1494 * }
1495 * ```
1496 *
1497 * ### PATCH Example
1498 * ```
1499 * // PATCH one of the heroes' name
1500 * patchHero (id: number, heroName: string): Observable<{}> {
1501 * const url = `${this.heroesUrl}/${id}`; // PATCH api/heroes/42
1502 * return this.httpClient.patch(url, {name: heroName}, httpOptions)
1503 * .pipe(catchError(this.handleError('patchHero')));
