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

Descriptionlink

\n

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

\n

You can pass an HttpRequest directly as the only parameter. In this case,\nthe call returns an observable of the raw HttpEvent stream.

\n

Alternatively you can pass an HTTP method as the first parameter,\na URL string as the second, and an options hash containing the request body as the third.\nSee addBody(). In this case, the specified responseType and observe options determine the\ntype of returned observable.

\n
    \n
  • The responseType value determines how a successful response body is parsed.
    • \n
  • If responseType is the default json, you can pass a type interface for the resulting\nobject as a type parameter to the call.
    • \n
\n

The observe value determines the return type, according to what you are interested in\nobserving.

\n
    \n
  • An observe value of events returns an observable of the raw HttpEvent stream, including\nprogress events by default.
    • \n
  • An observe value of response returns an observable of HttpResponse<T>,\nwhere the T parameter depends on the responseType and any optionally provided type\nparameter.
    • \n
  • An observe value of body returns an observable of <T> with the same T body type.

\n
\n mode_edit\n code\n
\n
\n
\n

Constructs an Observable that, when subscribed, causes a request with the special method\nJSONP to be dispatched via the interceptor pipeline.\nThe JSONP pattern works around limitations of certain\nAPI endpoints that don't support newer,\nand preferable CORS protocol.\nJSONP treats the endpoint API as a JavaScript file and tricks the browser to process the\nrequests even if the API endpoint is not located on the same domain (origin) as the client-side\napplication making the request.\nThe endpoint API must support JSONP callback for JSONP requests to work.\nThe resource API returns the JSON response wrapped in a callback function.\nYou can pass the callback function name as one of the query parameters.\nNote that JSONP requests can only be used with GET requests.

\n\n
\n
\n \n
\n

Constructs a JSONP request for the given URL and name of the callback parameter.

\n \n url\n string\n

\n\n
\n \n callbackParam\n string\n

Usage noteslink

\n

Sample HTTP requests for the Tour of Heroes application.

\n

HTTP Request Examplelink

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

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

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

JSONP Examplelink

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

PATCH Examplelink

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