error handling

Look at the error prompt above, contains multiple values "*" means that two cross-domain settings have been set. On our side, I have set cross-domain processing in nginx, and development has also set cross-domain processing in the program, but only one is allowed. Remove any of them. If the server is set to allow cross-domain, there is no need to set cross-domain in the Nginx proxy.
