ruby - 邮寄 gem : how to set an email to "read"?

Question

我必须用 Ruby 编写一个电子邮件导入程序，我偶然发现了 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

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
