Angular 2 http.get with params

You can leverage the URLSearchParams class for this:

getTranslation(lang: string): Observable<any> {
  let params = new URLSearchParams();
  params.set('param1', 'value1');

  return this.http.get(routes.Localization.Get, { search: params });
}

This will result to an URL like this (parameters are added in the query string): http://...?param1=value1.

See the documentation of this class:

• https://angular.io/docs/ts/latest/api/http/index/URLSearchParams-class.html

It now providers support for encoding / decoding parameters.

This is pretty simple - you can define your URLSearchParams and pass them in the second parameter of the http.get method:

import { URLSearchParams } from '@angular/http'

let params: URLSearchParams = new URLSearchParams();
params.set('param1', 'someValue');
params.set('param2', 'someValue');

return this.http.get(routes.Localization.Get, { search: params });
