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
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》中介绍获取单个模型的所有楼层信息。某些场景下根据需要也可以一次性获取多个模型的楼层信息。
请求地址：GET https://api.bimface.com/data/v2/files/{fileIds}/fileIdfloorsMappings
说明：一次性查询多个模型的楼层信息
参数：
请求 path(示例)：https://api.bimface.com/data/v2/files/1211223382064960,1211223382064961/fileIdfloorsMappings
多个模型之间，使用半角英文逗号分隔。
请求 header(示例)："Authorization: Bearer dc671840-bacc-4dc5-a134-97c1918d664b"
HTTP响应示例(200)：
{ "code": "success", "message": null, "data": [ { "fileId": "1211223382064960", "floors": [ { "archElev": 0, "areas": null, "elevation": 0, "height": null, "id": "311", "miniMap": "m.bimface.com/b5dee8260e202863066714ace1633ad9/resource/model/maps/1F.png", "name": "1F", "rooms": null, "structElev": 0 }, { "archElev": 4200, "areas": null, "elevation": 4200, "height": null, "id": "694", "miniMap": "m.bimface.com/b5dee8260e202863066714ace1633ad9/resource/model/maps/2F.png", "name": "2F", "rooms": null, "structElev": 4200 }, { "archElev": -9900, "areas": null, "elevation": -9900, "height": null, "id": "268400", "miniMap": null, "name": "-2F", "rooms": null, "structElev": -9900 } ] }, { "fileId": "1570831055575328", "floors": [ { "archElev": 0, "areas": null, "elevation": 0, "height": null, "id": "13071", "miniMap": null, "name": "F1", "rooms": null, "structElev": 0 }, { "archElev": 3500, "areas": null, "elevation": 3500, "height": null, "id": "15913", "miniMap": null, "name": "F2", "rooms": null, "structElev": 3500 } ] } ] }
该返回结果的结构比较复杂，包含每个模型的ID，以及每个模型包含的所有楼层信息。封装成对应的 C# MultipleModelsFloors.cs 类 ：
/// <summary> /// 获取多个模型的楼层信息 /// </summary> public class MultipleModelsFloors : GeneralResponse<List<MultipleModelsFloorsEntity>> { }
public class MultipleModelsFloorsEntity { [JsonProperty("fileId")] public string FileId { get; set; } [JsonProperty("floors")] public Floor[] Floors { get; set; } /// <summary>返回表示当前对象的字符串。</summary> /// <returns>表示当前对象的字符串。</returns> public override string ToString() { StringBuilder sb = new StringBuilder(); if (Floors != null && Floors.Length > 0) { foreach (var floor in Floors) { sb.AppendLine(floor.ToString()); } } return String.Format("[fileId={0}, floors={1}]", FileId, sb); } }
引用的 Floor 类，请参考《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》。
C#实现方法：

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。
以模型 “01_BIMFACE示例文件-Revit模型.rvt”、“GLD_结构B2.rvt” 为例测试上述的方法

测试代码如下：
1 // 获取多模型的楼层信息 2 protected void btnGetMultipleModelFloors_Click(object sender, EventArgs e) 3 { 4 string[] fileIds = txtFileID.Text.Split(','); 5 FileConvertApi api = new FileConvertApi(); 6 MultipleModelsFloors response = api.GetMultipleModelFloors(txtAccessToken.Text, fileIds, chkIncludeArea.Checked, chkIncludeRoom.Checked); 7 8 StringBuilder sb = new StringBuilder(); 9 List<MultipleModelsFloorsEntity> lstFloor = response.Data; 10 foreach (var floor in lstFloor) 11 { 12 sb.AppendLine(floor.ToString()); 13 } 14 15 txtResult.Text = response.Code.ToString2() 16 + Environment.NewLine 17 + response.Message.ToString2() 18 + Environment.NewLine 19 + sb; 20 }
成在管理，败在经验；嬴在选择，输在不学！ 贵在坚持！
