Cors issues when application server api applications (express) and Angulars js application are running on a different port

Question

I have a leisure api application written in node.js, and express runs on port 3000 and an angularjs application running on port 9001 on the same server. When rst api is called from an angularjs application, it gives a cors problem.

In the rest api application, I used the "cors" module

var cors = require('cors');

app.use(cors());

But it gives me the following error

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:3000/api/user/login. This can be fixed by moving the resource to the same domain or enabling CORS

The header of the request and response header is as follows:

Answer Header

Content-Length 222
Content-Type application/json; charset=utf-8
