HTTP post appends null to the data


I have this data coming from form using <form #form=“ngForm” (ngSubmit)=“myFunction(form.value)”>

I am sending the form value to HTTP post method as

let headers = new HttpHeaders({
‘Content-Type’: ‘application/x-www-form-urlencoded’,
return new Promise( resolve => {, formData, { headers: headers})
.subscribe( data => {

When i console the, i get

{name: ‘myname’, address:‘myaddress’}

what i get in the api is

{{“name”:“myname”, “address”:“myaddress”} : null }

which is making me hard to get the values in my backend.

P.S. I am using Laravel as Backend

Why is that : null is getting appended to the request?
How to get the values in the Laravel backend?


Don’t make headers objects and don’t instantiate promises.

The type of object you pass as a payload to the post call determines the content type. If it’s a PODO, the content type will be application/json. If it’s an instance of HttpParams, the content type will be application/x-www-form-urlencoded.

If you control the backend, the easiest solution would be to change it to accept JSON, at which point your client code becomes as simple as:

return, formData);

If you can’t do that, you will have to build up an HttpParams like so:

let body = new HttpParams();
for (let k in formData) {
  if (formData.hasOwnProperty(k)) {
    body = body.set(k, formData[k]);
return, body);
