Create the HTTP POST request body using an object in readiness for submission

Question

Create the HTTP POST request body using an object in readiness for submission

When sending the body of an http post request in Angular, I typically use the following approach:

  let requestBody: String = "";

  //dataObject is the object containing form values to send
  for (let key in dataObject) {
    if (dataObject[key]) {
      requestBody += (body.length ? '&' : '') + key + "=" + dataObject[key];
    }
  }

After assembling the requestBody, I include it in my http post request like this:

let headers = new Headers();
headers.append('Content-Type', 'application/x-www-form-urlencoded');
let requestOptions = new RequestOptions({ headers: headers });
//http represents an Http instance
http.post(URI, requestBody, requestOptions)

I'm curious if there is a more efficient way or a built-in method that allows for the direct usage of the dataObject within the post method rather than the aforementioned implementation.

Is there a way to achieve this using the deprecated Http Module? The new HttpClient does support it.

constructor(http: HttpClient) {
    let headers = new HttpHeaders();
    headers = headers.append('Content-Type', 'application/x-www-form-urlencoded');

    let params = new HttpParams()
    params = params.set('a', '1')
    http.post('/api/v1/login', params, {headers: headers}).subscribe(res => {});

}

Experiment with URLSearchParams for a different approach:

import { URLSearchParams } from '@angular/http';

//...

let params = new URLSearchParams();

for (const prop in newData) {
  params.set(prop, newData[prop]);
}
