请问体验版环境跟线上环境的url如何做到自动切换？How can the url of the trial version environment and the online environment switch automatically?

The URL of the small program request background is written by me in the app.js In the experience version, we point to the address of the test environment“ http://xxtest.com ”When it's time to go online, you can only manually change the address to the online environment, and then submit a version of the experience version for review. Then you have to manually change the address and go back. Is there any way to use a different configuration between the online environment and the experience version What about items
