listItem：delta

项目
04/30/2024

命名空间：microsoft.graph

获取新创建、更新或删除的列表项，而无需执行整个项目集合的完全读取。

一开始，应用不使用任何参数调用 delta。服务开始枚举列表的层次结构，返回项页，以及 @odata.nextLink 或 @odata.deltaLink。你的应用应继续使用 @odata.nextLink 调用，直到你看到返回 的 @odata.deltaLink 。

收到所有更改后，可以将它们应用于本地状态。若要检查将来的更改，请使用上一响应中的 @odata.deltaLink 再次调用 delta 。

增量源显示每项的最新状态，而不是每个更改的最新状态。如果项目重命名了两次，则仅显示一次，其最新名称为。由于各种原因，同一项可能会在增量源中多次出现。应使用最后一次出现的项。

应从本地州中删除具有此属性的项。

此 API 可用于以下国家级云部署。

权限

为此 API 选择标记为最低特权的权限。只有在应用需要它时，才使用更高的特权权限。有关委派权限和应用程序权限的详细信息，请参阅权限类型。要了解有关这些权限的详细信息，请参阅权限参考。

权限类型	最低特权权限	更高特权权限
委派（工作或学校帐户）	Sites.Read.All	Sites.ReadWrite.All
委派（个人 Microsoft 帐户）	不支持。	不支持。
应用程序	Sites.Read.All	Sites.ReadWrite.All

HTTP 请求

GET /sites/{siteId}/lists/{listId}/items/delta

查询参数

在请求 URL 中，可以包含以下可选查询参数。

参数	类型	说明
令牌	String	如果未指定，则枚举层次结构的当前状态。如果 `latest`为，则返回具有最新增量令牌的空响应。如果以前的增量令牌，则返回自该令牌以来的新状态。

此方法还支持 $select、 $expand和 $topOData 查询参数来自定义响应。

请求标头

标头	值
Authorization	持有者 {token}。必填。详细了解身份验证和授权。

请求正文

请勿提供此方法的请求正文。

响应

如果成功，此方法将在响应正文中返回 200 OK 响应代码和 listItem 对象集合。

除了 listItem 对象的集合外，响应还包含以下属性之一。

名称	值	说明
@odata.nextLink	URL	一个 URL，用于检索下一个可用更改页（如果当前集中存在更多更改）。
@odata.deltaLink	URL	返回当前所有更改后返回的 URL，而不是 @odata.nextLink。使用此属性可读取将来的下一组更改。

在某些情况下，服务返回一个 410 Gone 响应代码，其中包含一个错误响应，该响应包含以下错误代码之一，以及一个 Location 标头，该标头包含一个新的 nextLink ，用于启动新的增量枚举。当服务无法为给定令牌提供更改列表时，会出现这种情况。例如，如果客户端在长时间断开连接后尝试重用旧令牌，或者服务器状态已更改并且需要新令牌。

完成完整枚举后，将返回的项与本地状态进行比较，并根据错误类型按照说明进行操作。

错误类型	说明
resyncChangesApplyDifferences	将任何本地项替换为服务器 (版本，包括删除) （如果确定服务在上次同步时本地更改是最新的）。上载服务器并不清楚的任意本地更改。
resyncChangesUploadDifferences	上传服务未返回的任何本地项目，并上传与服务器版本不同的任何项。如果不确定哪个副本是最新的，请保留这两个副本。

除了重新同步错误和有关如何返回错误的更多详细信息，请参阅 Microsoft Graph 错误响应和资源类型。

在某些情况下，你可能想要请求当前 deltaLink 值，而不首先枚举列表中已有的所有项。如果你的应用只想要了解更改，而不需要了解现有项，这很有用。若要检索最新的 deltaLink，请使用查询字符串参数 ?token=latest调用 delta 。
