dynamic host for swagger ui 3.x

change_swagger_host.js

// not the most elgant way but it works 

// in the console post the function below and call changeSwagger("http","localhost:5050","/my_path/)

function changeSwagger (scheme,host,path) {
  var newspec = ui.spec().toJSON().resolved
  newspec.scheme = [scheme] || newspec.scheme 
  newspec.host = host || newspec.host
  newspec.basePath = path || newspec.basePath
  ui.getStore().dispatch({type:'set_scheme',payload: {scheme: newspec.scheme[0]}})
  ui.getStore().dispatch({type:'spec_update_resolved',payload:newspec})
}

It does not seem to work for openapi 3, is there any way to do it?
