// Initialize the WebMap and pass in the webmap idconst webmap = new WebMap({
portalItem: { // autocasts as new PortalItem()id: "471eb0bf37074b1fbb972b1da70fb310"// webmap id }

初始化 web 地图时，用户需要将 URL 设置为托管 web 地图的门户。默认门户 URL 为 "https://www.geoscene.cn"。为此，需要导入 geoscene/config 类，并设置其 portalUrl 集。以下代码段阐释了此工作流。

// Set the hostname to the on-premise portal geosceneConfig.portalUrl = "https://myHostName.domainName.com/webadaptorName";
