发送包含来自用户收件箱的不同邮件作为附件的新邮件

Dha*_*ana 4 outlook-restapi microsoft-graph-api

我正在开发一个多租户守护程序应用程序。应用程序需要代表用户发送电子邮件。应用程序发送的电子邮件必须包含来自用户收件箱的另一封电子邮件作为附件。

这可以通过简单地引用现有电子邮件的 id 而不是下载现有电子邮件的内容来实现吗？

我正在尝试下面这样的事情。使用sendMailapi 并尝试将现有电子邮件项目作为附件引用。但我收到此错误：

无法处理抽象类型的输入 Microsoft.OutlookServices.Item

我是在正确的方向吗？实现此用例的最佳方法是什么。

POST https://graph.microsoft.com/v1.0/me/sendMail HTTP/1.1
authorization: bearer {access_token}
content-type: application/json
content-length: 96

    "message": {
        "subject": "Meet for lunch?",
        "body": {
            "contentType": "Text",
            "content": "The new cafeteria is open."

您不能只提供id消息的。如果你这样做，你会得到一个空白的附件。不幸的是，API 没有设置为通过 ID 检索项目并为您插入。

所以这意味着您需要自己检索消息并将整个 JSON 有效负载包含item在附件的属性中。（参见https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/message_post_attachments）

您需要注意一个关键细节：在添加要附加的消息的 JSON 表示之前，您需要为其添加一个@odata.type属性，并将其设置为microsoft.graph.message.

例如：

获取要附加的消息

GET /me/messages/{id}
