background
Interface domain not hard-coded, but dynamic acquisition. Specific implementation is by reading a static json file to set the actual interface domain. Because before all the company's projects are of such a deal, the benefits of the original domain name is likely to be sealed, so you can directly modify the background operation configuration files; otherwise, h5 project might better say, app, then must be re-issued version.
