No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. The response had HTTP status code 401

Thank you @dknutsen for your valuable response. I found a solution to the error (No access-control-allow-origin ) , first thing if we want to make any rest call through our controller we make a request through the proxy.

so first start ember server with proxy

$ ember s --proxy https://www.abc.com/api

after that we make our rest call with only our respected method, not whole URL

Ember.$.ajax( {

        method : 'GET',
url : '/friends',

}).then((response) =>{

}

so in URL no need that domain name etc, directly calls our method that’s enough .

in this way, I solve the issue(No access-control-allow-origin).

cheers Happy EMBERING.
