express.io

问题 I try to connect from angular to a Express.io socket, but I have error 404 CORS. How can I solve this? XMLHttpRequest cannot load http://localhost:3000/socket.io/?EIO=3&transport=polling&t=1447367208172-29. No 'Access-Control-Allow-Origin' header is present on the requested resource.

In my express.io
