Description

HttpClient 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).

Methods

request()

Constructs an observable for a generic HTTP request that, when subscribed, fires the request through the chain of registered interceptors and on to the server.

Parameters

method

string

The HTTP method.

url

string

The endpoint URL.

options

object

The HTTP options to send with the request.

Optional. Default is undefined.

Returns

Observable<any>: An Observable of the reuested response, wuth body of type any.

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

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

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

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

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

delete()

Constructs an observable that, when subscribed, causes the configured DELETE request to execute on the server. See the individual overloads for details on the return type.

jsonp()

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

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

      
      jsonp(url: string, callbackParam: string): Observable<Object>

Parameters

`url`	`string`	The resource URL.
`callbackParam`	`string`	The callback function name.

Returns

Observable<Object>: An Observable of the response object, with response body as an object.

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

      
      jsonp<T>(url: string, callbackParam: string): Observable<T>

Parameters

url

string

The resource URL.

callbackParam

string

The callback function name.

You must install a suitable interceptor, such as one provided by HttpClientJsonpModule. If no such interceptor is reached, then the JSONP request can be rejected by the configured backend.

Returns

Observable<T>: An Observable of the response object, with response body in the requested type.

options()

Constructs an Observable that, when subscribed, causes the configured OPTIONS request to execute on the server. This method allows the client to determine the supported HTTP methods and other capabilites of an endpoint, without implying a resource action. See the individual overloads for details on the return type.
