how should I configure it?

Node.js vue-cli vue.js javascript

now that the proxy has been configured, axios does not need to set baseURL , otherwise it will not be processed by the agent.

const baseURL = "http://192.168.0.143:9300"

Change

const baseURL = ""

after setting proxyTable, you can no longer set baseURL

Cross-domain problem handling: the development environment uses proxyTable to configure the reverse proxy, while in the production environment, if the nginx server is used, the reverse proxy can be configured on the nginx, so the interface domain name is generally configured on the server
