nVisual二次开发——关于视图内对象的获取

nVisual作为一个图形化管理软件，首要的是将视图内对象渲染出来，对象渲染的数据来源于diagram接口，本章小编带大家了解这个接口。

• ​接口描述：传入视图节点id，获取视图属性、视图背景、视图内对象数据
• URL地址：http://ip:port /wapi/v1/diagram/{diagramId}
• 访问方法:：Get

样例传参：

常规视图：

localhost:8081/wapi/v1/diagram/24000000000001

地图：

localhost:8081/wapi/v1/diagram/24000000173161?top_left_x=12004144.930958997&top_left_y=5606184.75128747&bottom_right_x=13607488.03626885&bottom_right_y=4196074.4534825375&map_zoom=8&map_maxZoom=19

接口会根据传参返回当前视图要加载的数据的一切，包含：当前视图层级、视图权限、视图背景图片、视图宽高、视图比例、视图类型、内部节点对象、内部连线对象等…

返回成功样例​
