邮件宝石：如何将电子邮件设置为“阅读”？

Question

我必须用 Ruby 编写一个电子邮件导入器，我偶然发现了用于 Ruby 1.9 的非常漂亮的 Mail gem。我知道如何遍历未读消息，但我不知道如何将它们标记为已读（文档很详尽，但我真的不知道要注意什么）：

Mail.defaults do
  retriever_method :imap,
    address:    email_account.email_server.host,
    port:       email_account.email_server.port,
    user_name:  email_account.address,
    password:   email_account.password,
    enable_ssl: email_account.email_server.ssl
end

emails = Mail.find(
  what: :first,
  count: 3,
  order: :asc
)

emails.each do |email|
  # Do some stuff and then mark as read!
end

非常感谢您为我指明了正确的方向。

Answer 1

做起来很简单

Mail.defaults do
    retriever_method :imap,
    address:    email_account.email_server.host,
    port:       email_account.email_server.port,
    user_name:  email_account.address,
    password:   email_account.password,
    enable_ssl: email_account.email_server.ssl
end

Mail.find(what: :first, count: 3, order: :asc) do |email, imap, uid|
    # Do some stuff
    # ..
    # mark as read
    imap.uid_store( uid, "+FLAGS", [Net::IMAP::SEEN] )
end

请试试这个..

Mark IMAP Email as Read/Unread (Seen/Unseen):

require 'chilkat'

imap = Chilkat::CkImap.new()

#  Anything unlocks the component and begins a fully-functional 30-day trial.
success = imap.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print imap.lastErrorText() + "\n";
    exit
end

#  Connect to an IMAP server.
success = imap.Connect("mail.chilkatsoft.com")
if (success != true)
    print imap.lastErrorText() + "\n";
    exit
end

#  Login
success = imap.Login("myLogin","myPassword")
if (success != true)
    print imap.lastErrorText() + "\n";
    exit
end

#  Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
if (success != true)
    print imap.lastErrorText() + "\n";
    exit
end

#  Set PeekMode so that downloaded messages are not
#  automatically marked as seen.
imap.put_PeekMode(true)

#  The NumMessages property contains the number of messages
#  in the currently selected mailbox.
numMsgs = imap.get_NumMessages()
if (numMsgs == 0)
    exit
end

for i in 1 .. numMsgs
    #  Download each email by sequence number (not UID)

    # email is a CkEmail
    email = imap.FetchSingle(i,false)
    if (email == nil )
        print imap.lastErrorText() + "\n";
        exit
    end

    #  If desired, mark the email as SEEN.  There are two
    #  ways to do it:

    #  1) Set the flag directly by using the sequence number
    #  Indicate that we are passing a sequence number and
    #  not a UID:
    bIsUid = false
    #  Set the SEEN flag = 1 to mark the email as SEEN,
    #  or set it to 0 to mark it as not-seen.
    success = imap.SetFlag(i,bIsUid,"SEEN",1)
    if (success != true)
        print imap.lastErrorText() + "\n";
        exit
    end

    #  2) Alternatively, we can use the email object.
    #  When an email is downloaded from the IMAP server
    #  Chilkat will add a "ckx-imap-uid" header to the email.
    #  This makes it possible to know the UID associated with
    #  the email.  (This is not the sequence number, which may change
    #  from session to session, but the UID which does not change.
    #  The SetMailFlag method is identical to SetFlag, except
    #  it gets the UID from the ckx-imap-uid header.
    #  For example:
    success = imap.SetMailFlag(email,"SEEN",1)
    if (success != true)
        print imap.lastErrorText() + "\n";
        exit
    end

end

#  Disconnect from the IMAP server.
imap.Disconnect()

Mark All Unread Mail As Read In Ruby

试试这个：

Mail.find(keys: ['NOT','SEEN']) do |email, imap, uid|
  imap.uid_store(uid, "+FLAGS", [:Seen])
end
