How to handle CORS in angular?

Asked on May 08, 2018

I am using spring boot micro service with angular application. And I am using UAA as authorization server. If session expires means the application should show the message in pop up and should redirect to login page. How to achieve this in angular?

Can any one provide solution in this?

Thanks and Regards

If session expired means in the console it is trying to redirect to login page but the cross-origin request is blocking .
 I am getting the following error: 

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at localhost:8081/uaa/oauth/…. (Reason: CORS preflight channel did not succeed)

How to resolve this?

You need to allow cross-origin request. Use @CrossOrigin at server side controller and configure client domains. For example.  

@CrossOrigin(origins = {"http://localhost:8081", "http://localhost:8088"})
public class MyController {
