在上一篇《C#开发BIMFACE系列16 服务端API之获取模型数据1:查询满足条件的构件ID列表》中介绍了获取单文件(模型)的所有构建ID列表。每个构建由多种材质组成,本文介绍获取单个构建ID的材质列表。
请求地址:GET https://api.bimface.com/data/v2/files/{fileId}/elements/{elementId}/materials
说明:根据单个构建ID获取其所有材质
参数:
请求 path(示例):https://api.bimface.com/data/v2/files/1211223382064960/elements/618987/materials
请求 header(示例):"Authorization: Bearer dc671840-bacc-4dc5-a134-97c1918d664b"
HTTP响应示例(200):
{ "code" : "success", "data" : [ { "id" : "2856106", "name" : "METAL_(229,80,30)Steel", "parameters" : [ { "group" : "dimension", "items" : [ { "code" : "perimeter", "extension" : "object", "key" : "perimeter", "orderNumber" : 0, "unit" : "mm", "value" : 17200, "valueType" : 2 } ] } ] } ], "message" : "" }
该响应结果的结构比较复杂,封装成C#实体类 SingleModelSingleElementMaterials 如下:
1 ///2 /// 获取单个模型单个构件的材质列表返回的结果类 3 /// 4 public class SingleModelSingleElementMaterials : GeneralResponse > 5 { 6 7 }
1 public class MaterialInfo 2 { 3 [JsonProperty("id")] 4 public string Id { get; set; } 5 6 [JsonProperty("name")] 7 public string Name { get; set; } 8 9 [JsonProperty("parameters")] 10 public PropertyGroup[] Parameters { get; set; } 11 12 ///返回表示当前对象的字符串。 13 /// 表示当前对象的字符串。 14 public override string ToString() 15 { 16 StringBuilder sb = new StringBuilder(); 17 if (Parameters != null && Parameters.Length > 0) 18 { 19 foreach (var param in Parameters) 20 { 21 sb.AppendLine(param.ToString()); 22 } 23 } 24 25 return string.Format("[id={0}, name={1}, parameters={2}]", 26 Id, Name, sb); 27 } 28 }
1 public class PropertyGroup 2 { 3 [JsonProperty("group")] 4 public string Group { get; set; } 5 6 [JsonProperty("items")] 7 public PropertyItem[] Items { get; set; } 8 9 ///返回表示当前对象的字符串。 10 /// 表示当前对象的字符串。 11 public override string ToString() 12 { 13 StringBuilder sb = new StringBuilder(); 14 if (Items != null && Items.Length > 0) 15 { 16 foreach (var item in Items) 17 { 18 sb.AppendLine(item.ToString()); 19 } 20 } 21 22 return string.Format("[group={0}, items={1}]", 23 Group, sb); 24 } 25 }
1 public class PropertyItem 2 { 3 [JsonProperty("code")] 4 public string Code { get; set; } 5 6 [JsonProperty("extension")] 7 public object Extension { get; set; } 8 9 [JsonProperty("key")] 10 public string Key { get; set; } 11 12 [JsonProperty("orderNumber")] 13 public int? OrderNumber { get; set; } 14 15 [JsonProperty("unit")] 16 public string Unit { get; set; } 17 18 [JsonProperty("value")] 19 public object Value { get; set; } 20 21 [JsonProperty("valueType")] 22 public int? ValueType { get; set; } 23 24 ///返回表示当前对象的字符串。 25 /// 表示当前对象的字符串。 26 public override string ToString() 27 { 28 return string.Format("[code={0}, extension={1}, key={2}, orderNumber={3},unit={4},value={5},valueType={6}]", 29 Code, Extension, Key, OrderNumber, Unit, Value, ValueType); 30 } 31 }
C#实现方法:
1 ///2 /// 获取构件材质列表 3 /// 4 /// 令牌 5 /// 【必填】代表该单模型的文件ID 6 /// 【必填】代表该单模型的构件ID 7 /// 8 public virtual SingleModelSingleElementMaterials GetSingleModelSingleElementMaterials(string accessToken, long fileId,string elementId) 9 { 10 // GET https://api.bimface.com/data/v2/files/{fileId}/elements/{elementId}/materials 11 string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/elements/{1}/materials", fileId, elementId); 12 13 BimFaceHttpHeaders headers = new BimFaceHttpHeaders(); 14 headers.AddOAuth2Header(accessToken); 15 16 try 17 { 18 SingleModelSingleElementMaterials 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 (); 25 } 26 else 27 { 28 response = new SingleModelSingleElementMaterials 29 { 30 Message = httpResult.RefText 31 }; 32 } 33 34 return response; 35 } 36 catch (Exception ex) 37 { 38 throw new Exception("[获取构件材质列表]发生异常!", ex); 39 } 40 }
其中调用到的 httpManager.Get() 方法,请参考《C# HTTP系列》
以“01_BIMFACE示例文件-Revit模型.rvt”为例来测试。
完整的材质列表为:

更换其他的构建ID,再次查询

可以看到不同的构建ID,其组成材质不同。
测试代码如下:
1 // 获取构件材质列表 2 protected void btnGetSingleModelSingleElementMaterials_Click(object sender, EventArgs e) 3 { 4 FileConvertApi api = new FileConvertApi(); 5 6 string elementId = ddlSingleModelElements.SelectedValue; 7 8 SingleModelSingleElementMaterials response = api.GetSingleModelSingleElementMaterials(txtAccessToken.Text, txtFileID.Text.ToLong(), elementId); 9 10 txtResult.Text = response.Code.ToString2() 11 + Environment.NewLine 12 + "elementId:" + elementId 13 + Environment.NewLine 14 + response.Message.ToString2() 15 + Environment.NewLine 16 + response.Data.ToStringWith(","); 17 }
