大厦建筑模型中，基本上包含多个楼层，每个楼层包含多个房间等信息。在《C#开发BIMFACE系列21 服务端API之获取模型数据6：获取单模型的楼层信息》中介绍了如何获取一个模型中包含的楼层信息、面积分区、房间等信息。本篇主要介绍如何获取单个模型中单个房间信息。
请求地址：GET https://api.bimface.com/data/v2/files/{fileId}/rooms/{roomId}
说明：获取单个模型种单个房间信息
参数：
请求 path(示例)：https://api.bimface.com/data/v2/files/1211223382064960/rooms/857279
请求 header(示例)："Authorization: Bearer dc671840-bacc-4dc5-a134-97c1918d664b"
HTTP响应示例(200)：
{ "code" : "success", "data" : { "area" : 7.256476003661832E7, "bboxMax" : { "x" : -4938.068482562385, "y" : -3201.59397858169, "z" : 0.0 }, "bboxMin" : { "x" : -4938.068482562385, "y" : -3201.59397858169, "z" : 0.0 }, "boundary" : "", "id" : "313137", "levelId" : "11", "maxPt" : { "x" : -4938.068482562385, "y" : -3201.59397858169, "z" : 0.0 }, "minPt" : { "x" : -4938.068482562385, "y" : -3201.59397858169, "z" : 0.0 }, "name" : "dining room 4", "perimeter" : 40087.80000000279, "properties" : [ { "group" : "dimension", "items" : [ { "code" : "perimeter", "extension" : "object", "key" : "perimeter", "orderNumber" : 0, "unit" : "mm", "value" : 17200, "valueType" : 2 } ] } ] }, "message" : "" }
该返回结果的结构比较复杂。在文章最后会给出对应封装成的C#类。
C#实现方法：
1 /// <summary> 2 /// 获取单个模型中单个楼层信息 3 /// </summary> 4 /// <param name="accessToken">【必填】令牌</param> 5 /// <param name="fileId">【必填】代表该单模型的文件ID</param> 6 /// <param name="roomId">【必填】房间ID</param> 7 /// <returns></returns> 8 public virtual SingleModelSingleRoom GetSingleModelSingleRoom(string accessToken, long fileId, string roomId) 9 { 10 // GET https://api.bimface.com/data/v2/files/{fileId}/rooms/{roomId} 11 string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/rooms/{1}", fileId, roomId); 12 13 BimFaceHttpHeaders headers = new BimFaceHttpHeaders(); 14 headers.AddOAuth2Header(accessToken); 15 16 try 17 { 18 SingleModelSingleRoom response; 19 20 HttpManager httpManager = new HttpManager(headers); 21 HttpResult httpResult = httpManager.Get(url); 22 if (httpResult.Status == HttpResult.STATUS_SUCCESS) 23 { 24 response = httpResult.Text.DeserializeJsonToObject<SingleModelSingleRoom>(); 25 } 26 else 27 { 28 response = new SingleModelSingleRoom 29 { 30 Message = httpResult.RefText 31 }; 32 } 33 34 return response; 35 } 36 catch (Exception ex) 37 { 38 throw new Exception("[获取单个房间信息]发生异常！", ex); 39 } 40 }
其中调用到的 httpManager.Get() 方法，请参考《C# HTTP系列》
在BIMFACE的控制台中可以看到以下文件列表。模型状态均为转换成功。
以“Revit案例项目改.0001.rvt”为例测试上述的方法。
在《C#开发BIMFACE系列21 服务端API之获取模型数据6：获取单模型的楼层信息》中查询返回的结果中包含 RoomId
以 RoomID 为 857552 为例来查询该房间的详细信息
完整的房间信息如下：

该接口返回的响应信息，封装成对应的C# SingleModelSingleRoom 类：
