在《C#开发BIMFACE系列25 服务端API之获取模型数据9:获取楼层对应面积分区列表》一文中介绍了如何获取单个模型中单个楼层包含的面积分区列表。有了面积分区列表之后,即可查询单个面积分区的具体信息。
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面积分区包含的信息
参数:
请求 path(示例):https://api.bimface.com/data/v2/files/1211223382064960/areas/313467
请求 header(示例):"Authorization: Bearer dc671840-bacc-4dc5-a134-97c1918d664b"
HTTP响应示例(200):
{ "code" : "success", "data" : { "area" : 5.168684733047761E7, "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" : 28802.013920728663, "properties" : [ { "group" : "dimension", "items" : [ { "code" : "perimeter", "extension" : "object", "key" : "perimeter", "orderNumber" : 0, "unit" : "mm", "value" : 17200, "valueType" : 2 } ] } ], "viewName" : "1 1" }, "message" : "" }
封装成对应的C#类如下:
/// <summary> /// 获取单个面积分区信息返回的结果类 /// </summary> [Serializable] public class SingleModelSingleArea : GeneralResponse<Area> { }
其中 Area 类,请参考《C#开发BIMFACE系列25 服务端API之获取模型数据10:获取楼层对应面积分区列表》。
C#实现方法:
1 /// <summary> 2 /// 获取单个模型中单个面积分区信息 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="areaId">【必填】面积分区ID</param> 7 /// <returns></returns> 8 public virtual SingleModelSingleArea GetSingleModelSingleArea(string accessToken, long fileId, string areaId) 9 { 10 // GET https://api.bimface.com/data/v2/files/{fileId}/areas/{areaId} 11 string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/areas/{1}", fileId, areaId); 12 13 BimFaceHttpHeaders headers = new BimFaceHttpHeaders(); 14 headers.AddOAuth2Header(accessToken); 15 16 try 17 { 18 SingleModelSingleArea 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<SingleModelSingleArea>(); 25 } 26 else 27 { 28 response = new SingleModelSingleArea 29 { 30 Message = httpResult.RefText 31 }; 32 } 33 34 return response; 35 } 36 catch (Exception ex) 37 { 38 throw new Exception("[获取单个面积分区信息]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25 服务端API之获取模型数据10:获取楼层对应面积分区列表》中返回了2个面积分区ID,分别是1092832与1092841。
1092841完整的面积分区信息如下:
success [area=4333552.00744229, boundary={"version":"2.0", "loops":[[[{"z":2999.9998798520546,"y":-3201.5938503598827,"x":4505.6454184675295}, {"z":2999.9998798520546,"y":-3201.5938503598904,"x":7001.9312370150637} ], [{"z":2999.9998798520546,"y":-3302.5938463149096,"x":7001.9312370150637}, {"z":2999.9998798520546,"y":-1465.5939198856749,"x":7001.9312370150674} ], [{"z":2999.9998798520546,"y":-1465.5939198856749,"x":7001.9312370150665}, {"z":2999.9998798520546,"y":-1465.5939198856668,"x":4505.6454184675331} ], [{"z":2999.9998798520546,"y":-1465.5939198856677,"x":4505.6454184675331}, {"z":2999.9998798520546,"y":-3302.5938463149018,"x":4505.64541846753} ] ] ] }, id=1092841, levelId=, maxPt=[x=7001.93123701507, y=-1465.59391988567, z=2999.99987985205], minPt=[x=4505.64541846753, y=-3302.59384631491, z=2999.99987985205], name=面积 3, perimeter=8104.57151246125, properties=[group=其他, items=[code=, extension=, key=面积类型, orderNumber=,unit=,value=建筑公共面积,valueType=4] ] [group=尺寸标注, items=[code=, extension=, key=周长, orderNumber=,unit=mm,value=8105,valueType=2] [code=, extension=, key=计算高度, orderNumber=,unit=mm,value=0,valueType=2] [code=, extension=, key=面积, orderNumber=,unit=m²,value=4,valueType=2] ] [group=标识数据, items=[code=, extension=, key=名称, orderNumber=,unit=,value=面积,valueType=3] [code=, extension=, key=图像, orderNumber=,unit=,value=,valueType=4] [code=, extension=, key=注释, orderNumber=,unit=,value=,valueType=3] [code=, extension=, key=编号, orderNumber=,unit=,value=3,valueType=3] ] [group=限制条件, items=[code=, extension=, key=标高, orderNumber=,unit=,value=Level 2,valueType=4] ], viewName= ]
测试代码如下:
// 获取单个面积分区信息 protected void btnGetSingleModelSingleArea_Click(object sender, EventArgs e) { long fileId = txtFileID.Text.Trim().ToLong(); string areaId = txtAreaId.Text.Trim(); FileConvertApi api = new FileConvertApi(); SingleModelSingleArea response = api.GetSingleModelSingleArea(txtAccessToken.Text, fileId, areaId); txtResult.Text = response.Code.ToString2() + Environment.NewLine + response.Message.ToString2() + Environment.NewLine + response.Data; }
