问题描述
我正在尝试进入修订历史，但我不确定如何进入.无论我做什么，它都会返回 null.相关代码如下:
I am trying to get into the revision history, but I am unsure how to get to it. No matter what I do, it returns null. Relevant code is below:
string objectType = "HierarchicalRequirement";
string orderString = "";
bool fetchFullObjects = true;
long start = 1;
long pageSize = 200;
QueryResult queryResult = Global.service.query(Global.workspace, objectType, queryString, orderString, fetchFullObjects, start, pageSize);
int cnt = 0;
for (int i = 0; i < queryResult.Results.Length; i++)
{
// Results array is of type "DomainObject"
DomainObject rallyobject = queryResult.Results[i];
HierarchicalRequirement story = (HierarchicalRequirement)rallyobject;
var rev = story.RevisionHistory;
if (rev.Revisions != null)
{
// traverse revisions for info, never gets here
}
dataGridView3.Rows.Add(new object[] { story.FormattedID, story.Description, story.InProgressDate, story.AcceptedDate, story.PlanEstimate});
}
// Return the avereage days from inprogress to accepted
return;
}
在调试中，rev 总是返回 null..
In debug, rev always comes back null..
也许我的查询结果不正确??
Perhaps I am casting the query results incorrectly??
推荐答案
为了结束循环，这里有一个示例展示了如何执行 Kyle 提到的 service.read().Mark 建议使用 LBAPI 肯定会是一种更强大的跟踪工件快照的方法，但是您必须自己构建到 LBAPI 的 REST 查询 URL，Rally 没有用于 LBAPI 的 C# SDK(还).
To close the loop, here's an example showing how to do the service.read()'s that Kyle referred to. Mark's recommendation to use LBAPI will be a much more robust way to track artifact snapshots for sure, but you'll have to build the REST-query URL's to LBAPI on your own, Rally doesn't have a C# SDK for LBAPI (yet).
提醒一下，特别是如果您刚刚开始构建集成，我强烈建议您使用 Rally 的 .NET REST SDK 而不是 SOAP.
Just a heads-up, especially if you're just getting started with building your integration, I'd highly recommend using one of Rally's .NET REST SDK instead of SOAP.
REST 更健壮、性能更高，而且 Webservices API 1.4x(x 尚未确定)将成为支持 SOAP 的最终 API 版本.Webservices 2.x 将仅支持 REST，因此使用 REST 对于任何想要新的 Webservices 功能向前发展的人来说都是必不可少的.
REST is more robust, more performant, and, Webservices API 1.4x (x is yet-to-be-determined) will be the final API release to have SOAP support. Webservices 2.x will be REST-only, so using REST will be essential to anyone wanting new Webservices features moving forward.
