SharePoint Onlie REST Api LookUp查询

Question

我正在尝试构建SharePoint在线查询。有些专栏是 LookUp列。我想从uQmsParent列中获取源自我想要描述的列表的描述。该列被称为＆＃34; uQmsDescription＆＃34;。我用Google搜索并找到了很多答案。但是没有一个解决方案适合我。

查询：

_spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getbytitle('Processobjekt')/items?$select=Title,Id,uQmsDescription,uQmsOrder,uQmsType,uQmsBgColor,uQmsArea/Id,uQmsParent/Id,uQmsParent/Title,uQmsResponsible/Title,uQmsResponsible/uQmsName&$expand=uQmsArea,uQmsParent,uQmsResponsible&$filter=uQmsParent/Id eq '" + processItemId + "'&$orderby=uQmsOrder asc"

我可以毫不费力地获得身份和头衔。但是当我向选择查询添加uQmsParent / uQmsDescription时，我收到此错误The question in the uQmsParent/uQmsDescription field is not valid.

这就是查询生成错误的方式：

_spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getbytitle('Processobjekt')/items?$select=Title,Id,uQmsDescription,uQmsOrder,uQmsType,uQmsBgColor,uQmsArea/Id,uQmsParent/Id,uQmsParent/Title,uQmsParent/uQmsDescription, uQmsResponsible/Title,uQmsResponsible/uQmsName&$expand=uQmsArea,uQmsParent,uQmsResponsible&$filter=uQmsParent/Id eq '" + processItemId + "'&$orderby=uQmsOrder asc"

非常感谢帮助。

Answer 1

看起来您的查询错误，您没有在$ expand参数中获得所需的值。

它应该像：

$ select = Title，Id，uQmsDescription，uQmsOrder，uQmsType，uQmsBgColor，uQmsArea / Id，uQmsParent / Id，uQmsParent / Title，uQmsParent / uQmsDescription，uQmsResponsible / Title，uQmsResponsible / uQmsName＆amp; $ expand = uQmsArea / Title，uQmsParent /标题，uQmsResponsible /编号

这里非常好地解释了如何使用查找：
