本篇主要介绍如何获取一个模型中包含的三维视点或二维视图列表。
请求地址：GET https://api.bimface.com/data/v2/files/{fileId}/views
说明：获取单模型中包含的三维视点或二维视图列表。
参数：
请求 path(示例)：https://api.bimface.com/data/v2/files/1211223382064960/views
请求 header(示例)："Authorization: Bearer dc671840-bacc-4dc5-a134-97c1918d664b"
HTTP响应示例(200)：
{ "code" : "success", "data" : [ { "cropBox" : [ -12147.804809235151, -19279.554054815613, -30480.0, 22637.545576143948, 6805.089759789783, 30480.0 ], "elevation" : 0.0, "id" : "312", "levelId" : "312", "name" : "Level 1", "outline" : [ -146.52900292249365, -215.01048476685295, 240.3331231070219, 110.78415780710446 ], "preview" : { "height" : 0, "path" : "path", "width" : 0 }, "thumbnails" : [ "m.bimface.com/9b711803a43b92d871cde346b63e5019/resource/thumbnails/312/312.96x96.png" ], "viewPoint" : { "origin" : [ 0.0 ], "rightDirection" : [ 0.0 ], "scale" : 0, "upDirection" : [ 0.0 ], "viewDirection" : [ 0.0 ] }, "viewType" : "FloorPlain" } ], "message" : "" }
该返回结果的结构比较复杂，封装成如下的C#类
/// <summary> /// 获取三维视点或二维视图列表的返回结果类 /// </summary> [Serializable] public class SingleModelViews : GeneralResponse<List<ViewInfo>> { }
引用的 ViewInfo 类
/// <summary> /// 三维视点或二维视图 /// </summary> [Serializable] public class ViewInfo { /// <summary> /// 样例：[ -12147.804809235151, -19279.554054815613, -30480.0, 22637.545576143948, 6805.089759789783, 30480.0 ] /// </summary> [JsonProperty("cropBox")] public double?[] CropBox { get; set; } /// <summary> /// 样例：0.0 /// </summary> [JsonProperty("elevation")] public double?

其中引用的 Preview 类
[Serializable] public class Preview { /// <summary> /// 样例：0 /// </summary> [JsonProperty("height")] public int? Height { get; set; } [JsonProperty("path")] public string Path { get; set; } /// <summary> /// 样例：0 /// </summary> [JsonProperty("width")] public int? Width { 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() { return string.Format("[height={0}, path={1}, width={2}]", Height, Path, Width); } }
ViewPoint 类
[Serializable] public class ViewPoint { /// <summary> /// 样例 : [ 0.0 ] /// </summary> [JsonProperty("origin")] public double?[] Origin { get; set; } /// <summary> /// 样例 : [ 0.0 ] /// </summary> [JsonProperty("rightDirection")] public double?[] RightDirection { get; set; } /// <summary> /// 样例 : [ 0.0 ] /// </summary> [JsonProperty("scale")] public int? Scale { get; set; } /// <summary> /// 样例 : [ 0.0 ] /// </summary> [JsonProperty("upDirection")] public double?[] UpDirection { get; set; } /// <summary> /// 样例 : [ 0.0 ] /// </summary> [JsonProperty("viewDirection")] public double?[] ViewDirection { 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() { return String.Format("[origin={0}, rightDirection={1}, scale={2}， upDirection={3}, viewDirection={4}]", Origin.ToStringWith(","), RightDirection.ToStringWith(","), Scale, UpDirection.ToStringWith(","), ViewDirection.ToStringWith(",")); } }
C#实现方法：
1 /// <summary> 2 /// 获取三维视点或二维视图列表 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 /// <returns></returns> 7 public virtual SingleModelViews GetSingleModelViews(string accessToken, long fileId) 8 { 9 // GET https://api.bimface.com/data/v2/files/{fileId}/views 10 string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/views", fileId); 11 12 BimFaceHttpHeaders headers = new BimFaceHttpHeaders(); 13 headers.AddOAuth2Header(accessToken); 14 15 try 16 { 17 SingleModelViews response; 18 19 HttpManager httpManager = new HttpManager(headers); 20 HttpResult httpResult = httpManager.Get(url); 21 if (httpResult.Status == HttpResult.STATUS_SUCCESS) 22 { 23 response = httpResult.Text.DeserializeJsonToObject<SingleModelViews>(); 24 } 25 else 26 { 27 response = new SingleModelViews 28 { 29 Message = httpResult.RefText 30 }; 31 } 32 33 return response; 34 } 35 catch (Exception ex) 36 { 37 throw new Exception("[获取楼层对应面积分区列表]发生异常！", ex); 38 } 39 }
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。
