C#开发BIMFACE系列17 服务端API之获取模型数据2：获取构件材质列表

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：

/// <summary>
/// 获取单个模型单个构件的材质列表返回的结果类
/// </summary>
public class SingleModelSingleElementMaterials : GeneralResponse<List<MaterialInfo>>
{

}

public class MaterialInfo
{
[JsonProperty("id")]
public string Id { get; set; }

[JsonProperty("name")]
public string Name { get; set; }

[JsonProperty("parameters")]
public PropertyGroup[] Parameters { get; set; }

/// <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>
public override string ToString()
{
StringBuilder sb = new StringBuilder();
if (Parameters != null && Parameters.Length > 0)
{
foreach (var param in Parameters)
{
sb.AppendLine(param.ToString());
}
}

return string.Format("[id={0}, name={1}, parameters={2}]",
Id, Name, sb);
}
}

public class PropertyGroup
{
[JsonProperty("group")]
public string Group { get; set; }

[JsonProperty("items")]
public PropertyItem[] Items { 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()
{
StringBuilder sb = new StringBuilder();
if (Items != null && Items.Length > 0)
{
foreach (var item in Items)
{
sb.AppendLine(item.ToString());
}

3ff8
}

return string.Format("[group={0}, items={1}]",
Group, sb);
}
}

public class PropertyItem
{
[JsonProperty("code")]
public string Code { get; set; }

[JsonProperty("extension")]
public object Extension { get; set; }

[JsonProperty("key")]
public string Key { get; set; }

[JsonProperty("orderNumber")]
public int? OrderNumber { get; set; }

[JsonProperty("unit")]
public string Unit { get; set; }

[JsonProperty("value")]
public object Value { get; set; }

[JsonProperty("valueType")]
public int? ValueType { 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("
",
Code, Extension, Key, OrderNumber, Unit, Value, ValueType);
}
}

C#实现方法：

[code] /// <summary>
///  获取构件材质列表
/// </summary>
/// <param name="accessToken">令牌</param>
/// <param name="fileId">【必填】代表该单模型的文件ID</param>
/// <param name="elementId">【必填】代表该单模型的构件ID</param>
/// <returns></returns>
public virtual SingleModelSingleElementMaterials GetSingleModelSingleElementMaterials(string accessToken, long fileId,string elementId)
{
// GET https://api.bimface.com/data/v2/files/{fileId}/elements/{elementId}/materials
string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/elements/{1}/materials", fileId, elementId);

BimFaceHttpHeaders headers = new BimFaceHttpHeaders();
headers.AddOAuth2Header(accessToken);

try
{
SingleModelSingleElementMaterials response;

HttpManager httpManager = new HttpManager(headers);
HttpResult httpResult = httpManager.Get(url);
if (httpResult.Status == HttpResult.STATUS_SUCCESS)
{
response = httpResult.Text.DeserializeJsonToObject<SingleModelSingleElementMaterials>();
}
else
{
response = new SingleModelSingleElementMaterials
{
Message = httpResult.RefText
};
}

return response;
}
catch (Exception ex)
{
throw new Exception("[获取构件材质列表]发生异常！", ex);
}
}

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：

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：

[code] // 获取构件材质列表
protected void btnGetSingleModelSingleElementMaterials_Click(object sender, EventArgs e)
{
FileConvertApi api = new FileConvertApi();

string elementId = ddlSingleModelElements.SelectedValue;

SingleModelSingleElementMaterials response = api.GetSingleModelSingleElementMaterials(txtAccessToken.Text, txtFileID.Text.ToLong(), elementId);

txtResult.Text = response.Code.ToString2()
+ Environment.NewLine
+ "elementId:" + elementId
+ Environment.NewLine
+ response.Message.ToString2()
+ Environment.NewLine
+ response.Data.ToStringWith(",");
}
