C#開發BIMFACE系列16 服務端API之獲取模型數據1:查詢知足條件的構件ID列表

源文件/模型轉換完成以後,能夠獲取模型的具體數據。本篇介紹根據文件ID查詢知足條件的構件ID列表。html

請求地址:GET https://api.bimface.com/data/v2/files/{fileId}/elementIds
api

說明:根據六個維度(專業,系統類型,樓層,構件類型,族,族類型)獲取對應的構件ID列表,任何維度都是可選的。restful

構件ID分頁查詢相關請參考這裏 測試

同時,也支持根據空間關係從房間計算出房間內的構件ID列表this

構件與房間空間關係計算相關請參考這裏 url

參數:
spa

請求 path(示例):https://api.bimface.com/data/v2/files/1211223382064960/elementIdsrest

請求 header(示例):"Authorization: Bearer dc671840-bacc-4dc5-a134-97c1918d664b"code

HTTP響應示例(200):orm

{
    "code": "success",
    "message": null,
    "data": [
        "1107237",
        "1109326",
        "1107234",
        "1109327",
        "1107235",

        "1109329",
        "1107236",
        "1109325",
        "1107238",
        "1109328"
    ]
}

C#實現方法:

 3 /// </summary>
 4 /// <param name="accessToken">令牌</param>
 5 /// <param name="fileId">文件ID</param>
 6 /// <param name="request">請求參數對象</param>
 7 /// <returns></returns>
 8 public virtual FileElementsGetResponse GetFileElements(string accessToken, string fileId, FileElementsGetRequest request = null)
 9 {
10     // GET https://api.bimface.com/data/v2/files/{fileId}/elementIds
11     string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/elementIds", fileId);
12 
13     BimFaceHttpHeaders headers = new BimFaceHttpHeaders();
14     headers.AddOAuth2Header(accessToken);
15 
16     string data = string.Empty;
17     if (request != null)
18     {
19         data = request.SerializeToJson();
20     }
21 
22     try
23     {
24         FileElementsGetResponse response;
25 
26         HttpManager httpManager = new HttpManager(headers);
27         HttpResult httpResult = httpManager.Get(url, data);
28         if (httpResult.Status == HttpResult.STATUS_SUCCESS)
29         {
30             response = httpResult.Text.DeserializeJsonToObject<FileElementsGetResponse>();
31         }
32         else
33         {
34             response = new FileElementsGetResponse
35             {
36                 Message = httpResult.RefText
37             };
38         }
39 
40         return response;
41     }
42     catch (Exception ex)
43     {
44         throw new Exception("[查詢知足條件的構件ID列表]發生異常!", ex);
45     }
46 }

其中調用到的 httpManager.Get() 方法,請參考《C# HTTP系列》

測試

在BIMFACE的控制檯中能夠看到咱們上傳的文件列表,共計2個文件。模型狀態均爲轉換成功。

以「01_BIMFACE示例文件-Revit模型.rvt」爲例查詢其構建ID列表

查看結果中返回了構建ID列表。

若是使用 .dwg 二維文件進行測試則返回一下信息:unsupported operation:[please upgrade this databag to support specialty tree]

查詢知足條件的構件ID列表 ,只對三維模型適用。二維圖紙沒有目錄樹。

測試代碼以下:

// 查詢知足條件的構件ID列表
protected void btnGetFileElements_Click(object sender, EventArgs e)
{
    FileConvertApi api = new FileConvertApi();
    FileElementsGetResponse response = api.GetFileElements(txtAccessToken.Text, txtFileID.Text);

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

查詢構建ID列表返回類 FileElementsGetResponse 

/// <summary>
///  查詢知足條件的構件ID列表返回的結果類
/// </summary>
public class FileElementsGetResponse : GeneralResponse<List<string>>
{
}
