Ionic 2 how to do cross domain request?

Question

JavaScript

I am writing in ionic 2. I will send a request like this:

let headers = new Headers({
              'Content-Type':'application/x-www-form-urlencoded; charset=UTF-8'

            });
            let options = new RequestOptions({
              headers: headers,
              withCredentials: true,

            });
            this.items = 'l='+credentials.lgn+'&p='+credentials.pwd;
                this.http.post(this.apiUrl+credentials.sch + '/login', this.items, options)
                    .map(res => res.json())
                    .subscribe(data => {
                        console.log(data);

I get:
XMLHttpRequest cannot load edu.uray.ru:8082/5/login. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' localhost:8100 ' is therefore not allowed access.
In the response from the server in the "developer tools" in the browser, the response is received.
