从共享点获取元数据（列信息）

Question

我正在使用 Java (https://github.com/microsoftgraph/msgraph-sdk-java) 的 Microsoft Graph SDK 从 Sharepoint 中提取文档。除了 GraphServiceClient 提供的 "standard" 之外，是否还有可能提取有关文档的信息？

GraphServiceClient 的意思是我可以获得 createdBy、description、lastModifiedDateTime、webUrl... 并且我试图从中提取可以在 Sharepoint 中额外定义的信息 - 有可能进行自定义 fields/columns 用于文档并为每个文档设置值。

我想提取额外的 "metadata"。我该怎么做？

Answer 1

尝试将 $expand 添加到您的查询中。

items = client
  .users(mailbox)
  .drives(drive-id)
  .items(att.id)
  .buildRequest(Lists.newArrayList(new QueryOption("$expand","fields"))) 
  .get();

注：

Graph 无法检索所有自定义元数据 API。

短：

/items?expand=fields

我的实际测试查询：

https://graph.microsoft.com/v1.0/sites/{site id}/drives/{drive-id}/list/items?expand=fields

响应（MyTestMetadata1 是我的测试元数据）：

Answer 2

基本上，DriveItem 中关于共享点上的文件的信息较少。因此，使用 ListItem 获取为文档定义的所有内容...

IGraphServiceClient graphClient = GraphServiceClient.
                                  builder().
                                  authenticationProvider(authenticator).
                                  logger(new Slf4jGraphLogger(logger)).
                                  buildClient();

ListItem fileMetadata = 
           graphClient.
           drives(driveId).
           items(item.id).
           listItem().
           buildRequest().get();

那里的文件元数据 "fields" 存储了所有元数据，包括自定义元数据和常用元数据...

我对单个文档的测试查询是：

  https://graph.microsoft.com/v1.0/sites/{site id}/drives/{drive-id}/items/{item-id}/listItem

和

  https://graph.microsoft.com/v1.0/sites/{site id}/drives/{drive-id}/items/{item-id}/listItem/fields

回复和之前的回答一样
