Observables are lazy so you need to subscribe on them to make the request execute even if you don’t want to handle the response.
Something like that:
save(model) {
var uri = this._baseUri + "/api/contact/AddContact";
let md = JSON.stringify(model);
this.http.post(uri,
JSON.stringify(md),
{
headers: new Headers({
'Content-Type': 'application/json'
})
})
.map(res => res.json()).subscribe();
}
Hope it helps you,
