C#开发BIMFACE系列24 服务端API之获取模型数据9：获取单个房间信息

BIMFACE二次开发系列目录     【已更新最新开发文章，点击查看详细】

　　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：

63         if (Properties != null && Properties.Length > 0)
64         {
65             foreach (var property in Properties)
66             {
67                 sb.AppendLine(property.ToString());

72                              Area, BboxMax, BboxMin, Boundary, Id, LevelId, MaxPt, MinPt, Name, Perimeter, sb);
73     }
