How can I retrieve the list of IMAP UIDs from the selected folder? I want to get the list of mail UIDs, so I am passing the 1150 UID FETCH FLAGS (\Seen \Flagged), but I am not able to retrieve the list: it gives me an error like BAD Command. So how I can retrieve the list of UID from the selected folder?

推荐答案

列出当前所选文件夹中所有UID的最简单(也是最紧凑)的方法是通过UID SEARCH ALL:

The easiest (and most compact) way to list all the UIDs in the currently-selected folder is via UID SEARCH ALL:

A001 UID SEARCH ALL
* SEARCH 288 291 292 293 295 323 324 325 326 327 385 387 472 474 641 720 748
A001 OK UID SEARCH completed

UID FETCH请求中的错误是遗漏了序列集，并包括了标志列表.如果您将其改写为

The errors in your UID FETCH request were leaving out the sequence-set and including a list of flags. If you rewrote it as

A002 UID FETCH 1:* (UID)

或

A002 UID FETCH 1:* (UID FLAGS)

它会工作.
