TFS API - WIQL - 仅查询返回id和url

Question

我试图在TFS服务器上执行WIQL查询(按照此示例)并获取具有tittle和其他字段的工作项.即使我在输出中定义了我想要的列,json也只返回id和url.

询问

 Select [System.Title],
    [System.Description],
    [System.WorkItemType],[System.Id]
    From WorkItems 
    Where [System.WorkItemType] = 'Task' 
       AND [State] <> 'Closed' 
       AND [State] <> 'Removed' 
      AND [System.AssignedTo] = @me 
    order by [Microsoft.VSTS.Common.Priority] asc, [System.CreatedDate] desc

是否有任何标志我应该传递给查询,以便我可以在输出上获取这些字段？

Answer 1

从我可以看出的面值来看,问题是基于您引用的文档页面上提供的第一个POST示例.

查看json结果的内容,您会注意到以下json数组:

"workItems":[
{"id":7331, 
"url":"https://<hostname>/tfs/<collection>/_apis/wit/workItems/7331"}, ... etc.

在文档页面中阅读引用如下:

"执行查询后,使用查询结果响应中返回的ID获取工作项.一次最多可以获得200个工作项."

这意味着查询是一个两步过程

1.在第一次调用中检索工作项ID的列表.

2.通过进行额外的调用,检索第一个api调用中返回的工作项的更多细节.

200工作项限制的原因是有道理的,如果没有这样的限制,服务的响应性将受到负面影响.

然后,文档继续提供一个简明的示例,用于从第一个api调用中返回(在workItems数组中)返回的每个工作项ID的数据.

下面引用的示例(来自同一个文档),请注意在第一个查询中返回的ID将在此查询中使用:

GET: https://fabrikam.visualstudio.com/DefaultCollection/_apis/wit/WorkItems?ids=300,299,298,17,16,15,14,9,8&fields=System.Id,System.Title,System.State&asOf=2014-12-29T20:49:34.617Z&api-version=1.0

底线:此时,没有标志强制api返回初始查询产生的所有工作项.
