我目前有一个小问题，我不太确定如何解决它。情况是这样的。在 SharePoint 2013 中，我使用 REST-API 来更新和创建列表项。

如果有 ppl-Picker，则 Values 是 UserInformationList 中用户的 Id。到目前为止，一切都很好。但现在这是我的问题。

这不适用于尚未在 UserInformationList 中的用户。当我搜索尚不存在的用户时，nativc 中的 SharePoint 似乎会以某种方式发出 POST 请求。鉴于到目前为止在 ppl 选择器中输入的字符串，第一个似乎从另一个列表中获取用户。身体是这样的

   <?xml version="1.0" encoding="UTF-8"?>
<Request xmlns="http://schemas.microsoft.com/sharepoint/clientquery/2009" SchemaVersion="15.0.0.0" LibraryVersion="15.0.0.0" ApplicationName="Javascript Library">
   <Actions>
      <StaticMethod TypeId="{xxxxxxxxxxxxx}" Name="ClientPeoplePickerSearchUser" Id="5">
         <Parameters>
            <Parameter TypeId="{xxxxxxxxxxxxx}">
               <Property Name="AllowEmailAddresses" Type="Boolean">false</Property>
               <Property Name="AllowMultipleEntities" Type="Boolean">true</Property>
               <Property Name="AllUrlZones" Type="Boolean">false</Property>
               <Property Name="EnabledClaimProviders" Type="String" />
               <Property Name="ForceClaims" Type="Boolean">false</Property>
               <Property Name="MaximumEntitySuggestions" Type="Number">30</Property>
               <Property Name="PrincipalSource" Type="Number">15</Property>
               <Property Name="PrincipalType" Type="Number">1</Property>
               <Property Name="QueryString" Type="String">jack</Property>
               <Property Name="Required" Type="Boolean">false</Property>
               <Property Name="SharePointGroupID" Type="Number">0</Property>
               <Property Name="UrlZone" Type="Number">0</Property>
               <Property Name="UrlZoneSpecified" Type="Boolean">false</Property>
               <Property Name="Web" Type="Null" />
               <Property Name="WebApplicationID" Type="String">{00000000-0000-0000-0000-000000000000}</Property>
            </Parameter>
         </Parameters>
      </StaticMethod>
   </Actions>
   <ObjectPaths />
</Request>

然后它返回一个带有用户信息的 JSON。当我现在发送表单时，第二个 POST-Request 基本上包含所有的表单信息，看起来有点像这样

这第二篇文章似乎也以某种方式在 UserInformationList 中创建了用户。所以我的问题是。

有没有办法创建 UserInformationList 中尚不存在的用户并在创建后取回他们的 ID？

由于我只在前端开发了 SharePoint，所以我对它的架构不太熟悉。如果你们中的某个人可以在这里帮助我，那就太好了

您可以在 Web 上调用EnsureUser方法，该方法将创建用户（如果用户不存在）并返回其 ID。
