 public virtual SingleModelViews GetSingleModelViews(string accessToken, long fileId)

 {

     // GET https://api.bimface.com/data/v2/files/{fileId}/views

     string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/views", fileId);

     BimFaceHttpHeaders headers = new BimFaceHttpHeaders();

     headers.AddOAuth2Header(accessToken);

     try

     {

         SingleModelViews response;

         HttpManager httpManager = new HttpManager(headers);

         HttpResult httpResult = httpManager.Get(url);

         if (httpResult.Status == HttpResult.STATUS_SUCCESS)

         {

             response = httpResult.Text.DeserializeJsonToObject<SingleModelViews>();

         }

         else

         {

             response = new SingleModelViews

             {

                 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。

完整的视图列表为
