Question

有关更多背景信息，请参阅this thread。在弄清楚如何通过Office 365 Mail REST API从消息中检索ItemAttachments后，我现在遇到另一个问题：从ItemAttachments中检索FileAttachments。

API指南不包含此内容（据我所知）。当我检索ItemAttachment时，“HasAttachment”键的值为“true”，但我无法弄清楚如何检索它。

我（盲目地）尝试了以下URI：

/api/v1.0/me/messages/ {的MessageID} /附件/ {itemattachmentid}？$扩大= Microsoft.OutlookServices.ItemAttachment /项目/附件

/api/v1.0/me/messages/ {的MessageID} /附件/ {itemattachmentid}？$扩大= Microsoft.OutlookServices.ItemAttachment /项目/ Microsoft.OutlookServices.FileAttachment /文件

/api/v1.0/me/messages/ {的MessageID} /附件/ {itemattachmentid}？$扩大= Microsoft.OutlookServices.ItemAttachment /项目/文件

显然我不确定我在做什么：P

Answer 1

抱歉，目前暂不支持。我们将把它放在我们的产品积压上。

Answer 2

我们现在在API的Beta版本中支持此功能。您可以通过几种不同的方式从附加的消息或事件中获取附件。

通过扩展根消息

GET https://outlook.office.com/api/beta/me/messages/[message-id]?
$expand=Attachments($expand=Microsoft.OutlookServices.ItemAttachment/Item
($expand=Microsoft.OutlookServices.Event/Attachments))

注意：在上一个$expand我使用Microsoft.OutlookServices.Event作为类型，但您应该更改此项以匹配附加项的实际类型。对于消息，它将是Microsoft.OutlookServices.Message。
