获取邮件的 MIME 内容

  • 项目

MIME 是一种行业电子邮件标准。 许多电子邮件应用程序以 MIME 格式创建邮件并将其保存在扩展名为 .EML 的文件中。

即使 Outlook 不以 MIME 格式保存邮件，也有两种方法可以获得 MIME 格式的 Outlook 邮件正文：

  • 你可以将 $value 段附加到该邮件的 get-message 操作。
  • 如果邮件附加到 Outlook 项目或组帖子，则可以将 $value 段附加到该项目或组帖子的 get-attachment 操作。

在任何一种情况下，你的应用都必须具有访问 Outlook 项目或组帖子的相应权限才能应用 get-message 或 get-attachment 操作。

然后，你可以将邮件正文内容保存在 .EML 文件中，并将该文件附加到企业系统中的记录，例如 CRM、ERP 和错误跟踪的记录。

什么是 MIME？

MIME 是 Internet 电子邮件用于通过 SMTP 传输以下类型内容的标准：

  • 纯文本邮件
  • 带有可选内容（即，纯文本和 HTML）邮件
  • 回复邮件附上原始邮件
  • 带有图像、音频、视频或应用程序文件附件的文本邮件
  • 其他邮件构造

以下是邮件中的典型 MIME 标头。 有关详细信息，请参阅 RFC 2045。

  • MIME-Version - 指示邮件是 MIME 格式的。
  • Content-Type - 指示邮件或邮件的一部分的媒体类型，由类型和子类型表示。 它还包括一个 boundary 字段，该字段将字符串指定为 MIME 边界或封装边界，具体取决于 Content-Type 的位置。
  • Content-Disposition - 提供附件的详细信息，例如其演示样式（inline 或 attachment）、文件名、创建日期和上次修改日期。
  • Content-Transfer-Encoding - 指定表示二进制数据的编码方法。

获取 Outlook 邮件的 MIME 内容

你可以通过在获取邮件时附加 $value 段来获取邮件的 MIME 表示：

GET /users/{id}/messages/{id}/$value

示例

以下是请求使用其 MIME 内容返回登录用户邮箱中的邮件的示例。

GET https://graph.microsoft.com/v1.0/me/messages/4aade2547798441eab5188a7a2436bc1/$value

以下是答复。 MIME 内容以 MIME-Version 标头开头。

获取附加到 Outlook 项目或组帖子的 Outlook 邮件的 MIME 内容

你还可以获取 Outlook 邮件的 MIME 表示，如果邮件附加到 Outlook 事件、邮件、任务或组帖子，你的应用程序可以访问。

为此，标识邮件附件，并在获取该附件时附加 $value 段。 以下显示了访问附件的一些常用方法。 有关详细信息，请参阅获取附件。

如果邮件附加到用户默认日历中的事件：

GET /users/{id}/events/{id}/attachments/{id}/$value

如果邮件附加到用户邮箱中的其他邮件：

GET /users/{id}/messages/{id}/attachments/{id}/$value

如果邮件附加到用户默认任务文件夹中的 Outlook 任务：

GET /users/{id}/outlook/tasks/{id}/attachments/{id}/$value

如果邮件附加到指定的组帖子：

GET /groups/{id}/threads/{id}/posts/{id}/attachments/{id}/$value

示例

以下是获取已附加到另一封邮件的邮件，并以 MIME 格式返回正文的示例。

GET https://graph.microsoft.com/v1.0/me/messages/AAMkAGUAAA7XW-lAAA=/attachments/AAMkAGUAAA7XW-lAAABEgAQAFBZJBq4EN5FlCSvNV-M-FI=/$value
