• C#开发BIMFACE系列34 服务端API之模型对比5：获取模型构件对比差异

    　　BIMFACE平台提供了服务端“获取修改构件属性差异”API，其返回的结果也是一个列表，仅针对修改的构件（不包含新增、删除的构件），是指对于一个修改过的构件ID，其修改前后分别新增、删除了哪些属性，或是属性值发生了变化。

    请求地址：GET https://api.bimface.com/data/v2/comparisons/{comparisonId}/elementChange

    参数：

    请求 path(示例)：https://api.bimface.com/data/v2/comparisons/1136906400211168/elementChange?followingElementId=296524&followingFileId=1136893002033344&previousElementId=296524&previousFileId=1136239003943104

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

    HTTP响应示例(200)：

    C#实现方法：

11 public virtual ModelCompareChangeResponse GetModelCompareChange(string accessToken, long compareId,

13 {
14     // GET https: //api.bimface.com/data/v2/comparisons/{comparisonId}/elementChange
15     string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/comparisons/{0}/elementChange", compareId);

21     BimFaceHttpHeaders headers = new BimFaceHttpHeaders();
22     headers.AddOAuth2Header(accessToken);
23 
24     try

28         HttpManager httpManager = new HttpManager(headers);
29         HttpResult httpResult = httpManager.Get(url);
30         if (httpResult.Status == HttpResult.STATUS_SUCCESS)
31         {

    代码中使用的 HttpManager 类请参考我的博客文章《C# HTTP系列 HttpWebRequest 与 HttpWebResponse》。
