如何通过 Microsoft Graph API 检索 .msg（Outlook 项目）contentBytes？

Question

我正在尝试使用 Graph API 从 Outlook 中提取邮件附件，以便将它们添加到 DevOps 中的工作项中。这对于大多数附件类型（.jpg、.txt 等）来说很容易，因为我可以使用附件的 ID 进行调用，并且 returns JSON 响应包括附件的 contentBytes 属性.但是 Outlook 项目 (.msg) 附件不是这种情况；当我调用检索一个时，响应不包含 .msg contentBytes 属性并且 contentType 为 null，尽管它包含一个大小。这是我正在拨打的电话：

https://graph.microsoft.com/v1.0/me/mailfolders/AAMkADQ3MjYwZDViLTRlNzAtNDA1Ny04Zjc4LTUwYmM2Nzg2M2EyMAAuAAAAAAAfmvj9nlKwQplPl8PwU0KdsfdgfQBGOwCVHaiaRqlanlgEYx7vAAADnEUzAAA=/messages/AAMkADQ3MjYwZDViLTRlNzAtNDA1Ny04Zjc4LTUwYmM2Nzg2M2EyMABGAAAAAAAfmvj9nlKwQpldfgdgd8PwU0KbBwBGOwCVHaiaRqlanlgEYx7vAAADnEUzAABGOwCVHaiaRqlanlgEYx7vAAADnFF0AAA=/attachments/AAMkADQ3MjYwZDViLTRlNzAtNDA1Ny04Zjc4LTUwYmM2Nzg2M2EyMABGAAAAAAAfmvj9nlKwQplPl8PwU0KbBwBGOwCVHaiaRqlanlgEYx7vAAADnEUzAABGOwCVHadfgdfgRqlanlgEYx7vAAADnFF0AAABEgAQAI1OgY3EDyJOvJn5C5Y4EL4=?$expand=microsoft.graph.itemattachment/item

这是返回的示例：

}

有没有办法检索此附件的 contentBytes？如果没有，我是否应该只向包含 .msg 网络链接的工作项添加评论？

谢谢！

我相信你要找的是here。

GET https://graph.microsoft.com/v1.0/me/messages/AAMkAGUzY5QKjAAA=/attachments/AAMkAGUzY5QKjAAABEgAQAMkpJI_X-LBFgvrv1PlZYd8=/$value

注意末尾的 /$value 段。
