Description

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.

Usage Notes

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')));}
