java - 如何从 MessageIDTerm 获取 Yahoo IMAP 配置文件的消息？

Question

我正在尝试从消息 ID 获取 IMAP 消息，这种情况对于 Gmail 的 IMAP 服务器是成功的，即 imap.gmail.com 但同样我正在尝试使用 Yahoo IMAP 服务器 imap.mail.yahoo.com，inbox.search(searArr[0]) 返回 null。

我获取消息的代码块是-

Message[] msgs = null;
 MessageIDTerm[] searArr = new MessageIDTerm[]{new MessageIDTerm((String) strMessageID)};
 if (inbox != null && inbox.isOpen()) {
        msgs = inbox.search(searArr[0]);
  }
  for (int i = 0; i < msgs.length; i++) {
        System.out.println("Message: " + msgs[i]);
  }

我使用的是 JavaMail-1.4.5 版本。

这是一封 Yahoo 电子邮件的协议(protocol)跟踪 -

folder.search(MessageIDTerm) 适用于 Gmail。我发现两种类型的服务器在协议(protocol)跟踪中返回的响应之间存在许多差异。一件事我发现两条消息的字符集不同(Gmail 中 BODYSTRUCTURE 中的 CAPITAL 响应)-

For Yahoo -- ("charset" "utf-8") 
For Gmail -- ("CHARSET" "utf-8" "FORMAT" "fixed")

Yahoo 不支持通过MessageIDTerm 搜索消息吗？？在搜索 Yahoo 的 SearchTerm 时，我只找到了关于 Yahoo IMAP 帐户的 FlagTerm 的示例。

Yahoo 是否需要任何其他设置？或者 Yahoo 不支持搜索特定消息吗？？

更新:

我已经尝试更新 javaMail 的方法 - 1.5

  private int[] search(String msgSequence, SearchTerm term)
            throws ProtocolException, SearchException {

我在使用 folder.search 方法搜索时传递了“utf-8”来代替 null 它重新发送消息。变化是——

return issueSearch(msgSequence, term, "utf-8");

一个雅虎邮件的协议(protocol)跟踪在进行上述更改后现在是-

这是获取消息的正确方式吗？？

已编辑:覆盖 SearchTerm 类的 match() 方法以匹配 messageID-

SearchTerm messageIDTerm= new SearchTerm() {
                    @Override
                    public boolean match(Message message) {
                        try {
                            if (((MimeMessage) message).getMessageID().contains(sMessageId)) {
                                return true;
                            }
                        } catch (MessagingException ex) {
                            ex.printStackTrace();
                        }
                        return false;
                    }
                };

                msgs = folder.search(messageIDTerm);

此搜索返回由消息 ID 给出的消息。

谢谢

我的问题是通过重写 SearchTerm 类的 match() 方法来匹配 messageID-

  SearchTerm messageIDTerm= new SearchTerm() {
     @Override
     public boolean match(Message message) {
     try {
          if (((MimeMessage) message).getMessageID().contains(sMessageId)) {
                   return true;
          }
         } catch (MessagingException ex) {
                    ex.printStackTrace();
         }
          return false;
      }
 };
msgs = folder.search(messageIDTerm);

此搜索返回由消息 ID 给出的消息。我正在使用 JavaMail-1.5 版本。有用!!
