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》
测试
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：

]测试代码如下：
// 获取单个房间信息
protected void btnGetSingleModelSingleRoom_Click(object sender, EventArgs e)
{
long fileId = txtFileID.Text.Trim().ToLong();
string roomId = txtRoomId.Text.Trim();
FileConvertApi api = new FileConvertApi();
SingleModelSingleRoom response = api.GetSingleModelSingleRoom(txtAccessToken.Text, fileId, roomId);
txtResult.Text = response.Code.ToString2()
+ Environment.NewLine
+ response.Message.ToString2()
+ Environment.NewLine
+ response.Data;
}该接口返回的响应信息，封装成对应的C# SingleModelSingleRoom 类：
/// <summary>
/// 获取单个模型单个房间信息返回的结果类
/// </summary>
public class SingleModelSingleRoom : GeneralResponse<Room>
{
}Room 类如下：
