feat: update the assignment method of host in baseUrl

[junxiongchu]

Summary

When local development is allowed and the browser is automatically opened, the host of baseUrl uses the server host configuration by default, instead of directly defaulting to hard-coding localhost
(although it can be specified through open, it is more troublesome for those who use the default open configuration)
