Is there any spanning problem with websocket? Probably not, it’s probably a backend server problem

WEBSOCKET definitely has cross-domain issues. If cross-domain is required, settings must be made on both the server and client web pages. Cross-domain access must be allowed in the server code, and CSP must be set on the client web page. In this way, cross-domain issues can be dealt with.
