获取消息附件列表，而无需下载整个消息 [英] Get list of message attachments without downloading whole message

问题描述

我想要一种无需下载整个邮件即可获取邮件附件列表的方法.

I want a way to get a list of the attachments for a Message without having to download the whole message.

使用"Users.messages:获取"，我们可以设置要返回的字段，但我们只能选择有效载荷"，它将返回消息的整个有效载荷

With "Users.messages: get" we can set the fields to be returned but we can only choose "Payload" which will return the whole payload for the message

我只想要附件列表，以便用户可以选择要提取的附件.

I only want a list of the attachments so that the user can select which attachment to go and fetch.

有没有更有效的方法?

感谢您的帮助，

推荐答案

不幸的是，目前没有.就是说，执行get?format = FULL应该是非常有效的，而不是那么大的响应(几百KB)-它通常不会返回任何很大的主体部分，因此主要是元数据.通常，人们不仅想要一个附件列表，而且还想要有关这些附件的元数据(文件名，大小，类型，配置，它们在MIME树中的位置)，因为顶级附件可能不适合以与附件相同的方式显示. .eml附件中的附件等).

Unfortunately, no there is not currently. That said, doing a get?format=FULL should be pretty efficient and not that large of a response (few hundred KB)--it won't typically return any body parts that are very large so it's mostly just metadata. Typically people don't want just a list of attachments but also metadata about those attachments (filename, size, type, disposition, where they are in the MIME tree since a top-level attachment may not make sense to surface the same way as an attachment inside a .eml attachment, etc).
