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 /// <summary>  2 /// 获取单个模型单个构件的材质列表返回的结果类  3 /// </summary>  4 public class SingleModelSingleElementMaterials : GeneralResponse<List<MaterialInfo>>  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     /// <summary>返回表示当前对象的字符串。</summary>  13     /// <returns>表示当前对象的字符串。</returns>  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     /// <summary>返回表示当前对象的字符串。</summary>  10     /// <returns>表示当前对象的字符串。</returns>  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     /// <summary>返回表示当前对象的字符串。</summary>  25     /// <returns>表示当前对象的字符串。</returns>  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 /// <summary>   2 ///  获取构件材质列表   3 /// </summary>   4 /// <param name="accessToken">令牌</param>   5 /// <param name="fileId">【必填】代表该单模型的文件ID</param>   6 /// <param name="elementId">【必填】代表该单模型的构件ID</param>   7 /// <returns></returns>   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<SingleModelSingleElementMaterials>();  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》

测试

在BIMFACE的控制台中可以看到我们上传的文件列表,共计2个文件。模型状态均为转换成功。

以“01_BIMFACE示例文件-Revit模型.rvt”为例来测试。

 完整的材质列表为:

[id=268711, name=金属 - 铝, parameters=[group=标识数据, items=[code=, extension=, key=型号, orderNumber=,unit=,value=,valueType=3]  [code=, extension=, key=成本, orderNumber=,unit=,value=0.00,valueType=2]  [code=, extension=, key=URL, orderNumber=,unit=,value=,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=注释记号, orderNumber=,unit=,value=,valueType=3]  [code=, extension=, key=标记, orderNumber=,unit=,value=,valueType=3]  [code=, extension=, key=制造商, orderNumber=,unit=,value=,valueType=3]  [code=, extension=, key=说明, orderNumber=,unit=,value=,valueType=3]  ]  [group=材质和装饰, items=[code=, extension=, key=名称, orderNumber=,unit=,value=金属 - 铝,valueType=3]  [code=, extension=, key=高光, orderNumber=,unit=,value=128,valueType=1]  [code=, extension=, key=辉光, orderNumber=,unit=,value=False,valueType=1]  [code=, extension=, key=平滑度, orderNumber=,unit=,value=50,valueType=1]  [code=, extension=, key=透明度, orderNumber=,unit=,value=0,valueType=1]  ]  ]

更换其他的构建ID,再次查询

完整的材质列表为:

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 }
