If use autoPort, how to specify the port in config

[daolou]

If use autoPort, how to specify the port in config

this:

    if (!assetsConfig.url) {
      assetsConfig.url = 'http://127.0.0.1:' + port;
    } else {
      assetsConfig.url = assetsConfig.url + ':' + port;
    }

In addition, if someone want use himself url, in that case, he/she should know the port.
