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>>

22             }
23         }
24 
25         return string.Format("[id={0}, name={1}, parameters={2}]",

30     }

C#实现方法:

 1 /// <summary>

 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:

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 }
