Question

无论如何是否有来获取最新消息，或者是50个最高的uid？

func getCode(findEmail string) (string, error) {
    uids, err := im.GetUIDs("1:*")
    if err != nil {
        imapLock.RUnlock()
        return "", err
    }

    if len(uids) > 50 {
        uids = uids[len(uids)-50:]
    }

    emails, err := im.GetEmails(uids...)
    if err != nil {
        return "", err
    }

    for _, email := range emails {
        // do something
    }
}

将您的UID提取范围定型为“*”或使用排序（如果支持）：uids, err := im.GetUIDs("50:*") // Fetch last 50 UIDs

Answer 1

or

uids, err := im.GetSortedUIDs("REVERSE DATE", 50) // If sorting is supported
