HttpClient

class

Perform HTTP requests.

      
      class HttpClient {
  request(first: string | HttpRequest<any>, url?: string, options: {...}): Observable<any>
  delete(url: string, options: {...}): Observable<any>
  get(url: string, options: {...}): Observable<any>
  head(url: string, options: {...}): Observable<any>
  jsonp<T>(url: string, callbackParam: string): Observable<T>
  options(url: string, options: {...}): Observable<any>
  patch(url: string, body: any | null, options: {...}): Observable<any>
  post(url: string, body: any | null, options: {...}): Observable<any>
  put(url: string, body: any | null, options: {...}): Observable<any>
}

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 according to which signature is called (mainly the values of observe and responseType).

Methods

request()

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

Optional. Default is undefined.

Returns

Observable<any>: an Observable of whatever was requested, typed to any.

This method can be called in one of two ways. Either an HttpRequest instance can be passed directly as the only parameter, or a method can be passed as the first parameter, a string URL as the second, and an options hash as the third.

If a HttpRequest object is passed directly, an Observable of the raw HttpEvent stream will be returned.

If a request is instead built by providing a URL, the options object determines the return type of request(). In addition to configuring request parameters such as the outgoing headers and/or the body, the options hash specifies two key pieces of information about the request: the responseType and what to observe.

The responseType value determines how a successful response body will be parsed. If responseType is the default json, a type interface for the resulting object may be passed as a type parameter to request().

The observe value determines the return type of request(), based on what the consumer is interested in observing. A value of events will return an Observable<HttpEvent> representing the raw HttpEvent stream, including progress events by default. A value of response will return an Observable<HttpResponse<T>> where the T parameter of HttpResponse depends on the responseType and any optionally provided type parameter. A value of body will return an Observable<T> with the same T body type.

delete()

Constructs an Observable which, when subscribed, will cause the configured DELETE request to be executed on the server. See the individual overloads for details of delete()'s return type based on the provided options.

jsonp()

Constructs an Observable which, when subscribed, will cause a request with the special method JSONP to be dispatched via the interceptor pipeline.

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

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

Parameters

url	Type: `string`.
callbackParam	Type: `string`.

Returns

Observable<Object>: an Observable of the response object as an Object
