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，这个案例对于用于Gmail的IMAP服务器（即IMAP）是成功的。gmail。com，但我正在尝试使用雅虎IMAP服务器。邮政雅虎。com，收件箱。搜索（searrr[0]）返回null。

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电子邮件的协议跟踪-

文件夹Gmail搜索（MessageIDTerm）工作正常。我发现这两种类型的服务器在协议跟踪中返回的响应之间存在许多差异。我发现两条消息的字符集不同（Gmail中BODYSTRUCTURE的大写字母）-

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

Yahoo不支持MessageIDTerm搜索消息吗？？在为Yahoo搜索SearchTerm时，只有我在Yahoo IMAP帐户中找到了关于FlagTerm的示例。

雅虎是否需要任何其他设置？或者Yahoo不支持搜索特定消息？？

更新：

我已经尝试了javaMail-1.5的更新方法

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

我通过了“utf-8”来代替null它在使用folder.search方法插入时返回消息。变化是-

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

一封雅虎邮件的协议跟踪现在是在进行上述更改后-

这是获取信息的正确方式吗？？

已编辑：将SearchTerm类的方法match（）重写为match 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message-ID给出的消息。

谢谢

Answer 1

我假设您已确保邮箱中确实存在具有该邮件ID的邮件？

查看YahooIMAP服务器实际返回的内容会很有趣。尝试打开会话调试并查看协议跟踪。YahooIMAP服务器可能不支持此功能；它似乎只支持现有移动客户端的需求。

Answer 2

通过将SearchTerm类的方法match（）重写为match messageID，我的问题得以解决-

  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message-ID给出的消息。我使用的是JavaMail-1.5版本。它起作用了！！
