The HttpClient methods allow you to configure the parameters in the options.

Import the HttpClientModule from the @angular/common/http package to configure it.

import {HttpClientModule} from '@angular/common/http';

  imports: [ BrowserModule, HttpClientModule ],
  declarations: [ App ],
  bootstrap: [ App ]
export class AppModule {}


Following that, you can inject the HttpClient and use it to execute the request.

import {HttpClient} from '@angular/common/http'

  selector: 'my-app',
  template: `
      <h2>Hello {{name}}</h2>
export class App {
  constructor(private httpClient: HttpClient) {
    this.httpClient.get('/url', {
      params: {
        appid: 'id1234',
        cnt: '5'
      observe: 'response'
    .then(response => {

You can achieve the same thing with Angular versions prior to version 4 by utilizing the HTTP service.

As a second parameter, the HTTP. get function accepts an object that implements RequestOptionsArgs.

The object’s search field may be used to set a string or a URLSearchParams object.


An example:

let params: URLSearchParams = new URLSearchParams();
params.set('appid', StaticSettings.API_KEY);
params.set('cnt', days.toString());

//Http request-
return this.http.get(StaticSettings.BASE_URL, {
  search: params
  (response) => this.onGetForecastResult(response.json()), 
  (error) => this.onGetForecastError(error.json()), 
  () => this.onGetForecastComplete()
