如何使用 sp.web SPFX 检索计算列值

Question

我正在创建一个 SPFX (ReactJS/TypeScript) webpart 并使用：

let docs = sp.web.lists.getByTitle("Case Documents").items.select("ID","Title","CaseID").orderBy("Modified", true).get();

尝试从 SharePoint DOC 库中检索列值。 CaseID 是查看 SP 列表的查找列。查找列中有从其他列表填充的值。

我可以从图书馆获取 Id 和 Title 值，但不能获取 CaseID（查找列）。我收到此错误：

Uncaught (in promise) Error: Error making HttpClient request in queryable [400]  ::> 
{"odata.error":{"code":"-1, Microsoft.SharePoint.SPException","message":
{"lang":"en-US","value":"The query to field 'CaseID' is not valid. 
The $select query string must specify the target fields and the $expand query string must contains CaseID."}}}

知道是什么原因造成的吗？

您可以通过以下方式获取查找列值的查找值：

let docs = sp.web.lists.getByTitle("Case Documents").items.select("ID","Title","CaseID/Title", "CaseID/ID").expand("CaseID").orderBy("Modified", true).get();
