如何使用Microsoft Graph更新SharePoint中的查找字段和用户字段?

问题描述：

我正在寻找一种如何使用Microsoft graph更新查找字段和用户字段的方法? 我可以阅读该项目，但是即使输入正确的ID值，也找不到创建或更新此类字段的方法.

I'm looking for a way how to update a lookup field and a user field with Microsoft graph ? I can read the item, but I don't find a way to create or update this kind of field even if I put a correct ID value.

答

现在，它支持通过Microsoft Graph API更新查找字段.

Nowadays it is supported to update lookup fields via Microsoft Graph API.

让我们说有一个名为Category的字段，然后根据查找字段是以单值还是多值表示，下面的示例演示了如何设置查找字段值.

Lets say there is a field named Category, then depending whether lookup field is represented as single or multi valued, the following examples demonstrate how to set lookup field value.

用于单值字段:

Url: https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}/fields    
Method: PATCH 
Body: {
  "CategoryLookupId": "1"
}

其中

field name以以下格式提供:{field-name}LookupId
field value对应于查找ID，并以字符串形式提供

field name is provided in the following format: {field-name}LookupId
field value corresponds to lookup id and provided as a string

用于多值字段

Url: https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}/fields    
Method: PATCH 
{
    "CategoryLookupId@odata.type": "Collection(Edm.String)",
    "CategoryLookupId":["1","2"]
}
