在《C#开发BIMFACE系列22 服务端API之获取模型数据7：获取多个模型的楼层信息》中，返回的楼层信息结果中包含了楼层的具体信息，其中包含楼层ID。
一个楼层中可能包含多个面积分区，本文介绍如何获取楼层对应面积分区列表。
请求地址：GET https://api.bimface.com/data/v2/files/{fileId}/areas
说明：获取单个模型中单个楼层对应的分区列表。
参数：
请求 path(示例)：https://api.bimface.com/data/v2/files/1211223382064960/areas?floorId=311
请求 header(示例)："Authorization: Bearer dc671840-bacc-4dc5-a134-97c1918d664b"
HTTP响应示例(200)：

封装成对应的C#类：
/// <summary>
/// 获取单个模型种单个楼层对应面积分区列表的返回结果类
/// </summary>
public class SingleModelSingleFloorAreas : GeneralResponse<List<Area>>
{ }
其中 Area 类定义为
/// <summary>
/// 楼层区域信息
/// </summary>
[Serializable]
public class Area
{
/// <summary>
/// 样例 : 7.256476003661832E7

public string Boundary { get; set; } /// <summary>

[JsonProperty("id")]
public string Id { get; set; } /// <summary>

[JsonProperty("levelId")]
public string LevelId { get; set; } [JsonProperty("maxPt")]
public Coordinate MaxPt { get; set; } [JsonProperty("minPt")]

public override string ToString()

if (Properties != null && Properties.Length > )
{
foreach (var property in Properties)
{
sb.AppendLine(property.ToString());
}
} return string.Format("[area={0}, boundary={1}, id={2}, levelId={3}, maxPt={4}, minPt={5}, name={6}, perimeter={7}, properties={8}, viewName={9}]",
AreaValue, Boundary, Id, LevelId, MaxPt, MinPt, Name, Perimeter, sb, ViewName);
}
}
其中 Coordinate 、PropertyGroup 类请参考《C#开发BIMFACE系列17 服务端API之获取模型数据2：获取构件材质列表》。
C#实现方法：
/// <summary>
/// 获取单个模型中单个楼层对应面积分区列表
/// </summary>
/// <param name="accessToken">【必填】令牌</param>
/// <param name="fileId">【必填】代表该单模型的文件ID</param>
/// <param name="floorId">【必填】代表该单模型的楼层ID</param>
/// <returns></returns>
public virtual SingleModelSingleFloorAreas GetSingleModelSingleFloorAreas(string accessToken, long fileId, string floorId)
{
// GET https://api.bimface.com/data/v2/files/{fileId}/areas
string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/areas?floorId={1}", fileId, floorId); BimFaceHttpHeaders headers = new BimFaceHttpHeaders();
headers.AddOAuth2Header(accessToken); try
{
SingleModelSingleFloorAreas response; HttpManager httpManager = new HttpManager(headers);
HttpResult httpResult = httpManager.Get(url);
if (httpResult.Status == HttpResult.STATUS_SUCCESS)
{
response = httpResult.Text.DeserializeJsonToObject<SingleModelSingleFloorAreas>();
}
else
{
response = new SingleModelSingleFloorAreas
{
Message = httpResult.RefText
};
} return response;
}
catch (Exception ex)
{
throw new Exception("[获取楼层对应面积分区列表]发生异常！", ex);
}
}
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我们上传的文件列表，模型状态均为转换成功。
使用“bimface_2018_mdv_room.rvt”为例测试上述方法。
在《C#开发BIMFACE系列22 服务端API之获取模型数据7：获取多个模型的楼层信息》中可以查询到该文件的楼层信息
下面查询 FloorID 等于 245423 的面积分区列表
查询到的完整的面积分区列表为
