Angular 4 : " Set Cookie " flag in Http response is not setting Cookie in browser

Question

I'm working on a Website using Angular 4. We are using Cookie authentication method. After login process API response have cookie in Set Cookie field. But its not setting value in browser. So authentication of other APIs get failed. While using postman its working fine. Following is the Angular code using http get method ( this Api is created for testing purpose.)

this.http.get(
'http://test.xxx.com/test/testjsondata/login', 
{ withCredentials : true}
) 
.map(res => res.json()).
subscribe(data => {   console.log(data); });
