JavaMail IMAP郵件內容SSL/NON SSL

我在JavaMail中遇到了有關IMAP的奇怪問題。JavaMail IMAP郵件內容SSL/NON SSL

我已經知道很多關於JavaMail，我也知道在哪裏尋找問題/答案，但我找不到這個問題的解決方案。

我有IMAP頻道，我可以在其上設置啓用或禁用SSL。當我創建新的電子郵件（例如，主題：「TEST」，正文：「HELLO」）並從Thunderbird客戶端發送，以便能夠使用我的IMAP頻道下載它時，情況變得很奇怪。

在SSL啓用上，一切正常。（在我的IMAP頻道），我從電子郵件文件夾中獲得消息，成功連接到商店後，然後我從此消息getContent（）（它始終是字符串類型，而不是MimeMultipart或多部分），並且輸出爲「HELLO」。

但是，在SSL DISABLED上，一切都正常，但我收到不同的身體。它看起來像整個消息解析（看下面）

message.getContent（）。toString（）;使用SSL

HELLO

message.getContent（）。toString（）;不使用SSL

有沒有人有任何想法是怎麼回事？下面是我的代碼片段（向您展示最重要的部分：

// properties used to create session 
String protocol = useSSL ? "imaps" : imap"; 

properties.setProperty("mail.store.protocol", protocol); 
properties.setProperty("mail." + protocol + ".host", ...); 
properties.setProperty("mail." + protocol + ".user", ...); 
properties.setProperty("mail." + protocol + ".port", ...); 
properties.setProperty("mail." + protocol + ".password", ...); 

// only when using ssl 
properties.setProperty("mail.imaps.auth", "true"); 
properties.setProperty("mail.imaps.starttls.enable", "true"); 
properties.setProperty("mail.imaps.ssl.checkserveridentity", "true"); 
properties.setProperty("javax.net.ssl.trustStore", ...); 
properties.setProperty("javax.net.ssl.trustStorePassword", ...); 

// get store and other important things 
Store store = this.session.getStore(protocol); 
Folder folder = store.getFolder("INBOX"); 
folder.open(Folder.READ_WRITE); 
Message[] newMessages = folder.getMessages(); 
for (Message newMessage : newMessages) { 
    Object o = newMessage.getContent(); 
    System.out(o.toString()); // should write "HELLO", but instead it parses whole message (only on NON SSL MODE!) 
}

//編輯：加調試信息 //編輯2：調試信息包含使用{CONTENT_INFO，旗幟獲取的文件夾，現在全部細節，信封}

服務器hMailServer，在啓用SSL和NONSSL 127.0.0.1端口運行。

它的出現，我得到的郵件只有標題，但不是身體..

感謝您的任何建議，祝您有美好的一天！

是否在SSL和非SSL端口上運行相同的服務器軟件？ – Max

如果打開JavaMail會話調試，協議跟蹤會顯示什麼內容？每種情況下您使用的是哪種類型的服務器？ –

我以郵編編輯的形式回覆 – Przunk

我解決了這個問題。我遇到的錯誤鏈接到「無法加載BODYSTRUCTURE」錯誤（下面的鏈接 - 閱讀有關IMAP的複雜性）。

https://java.net/projects/javamail/pages/Exchange

http://www.oracle.com/technetwork/java/javamail/faq/index.html#imapserverbug

所有這一切必須做的，以獲得適當的身體信息，是創建郵件的副本，使用的MimeMessage構造函數。

// newMessages - it is array of messages from the mail inbox 
// create copy of the message using MimeMessage constructor 
MimeMessage message = new MimeMessage(newMessages[0]); // without it, the content was as in my first post 
// get content from the mssage 
Object messageContent = message.getContent(); 
// output it as a string 
System.out.println(messageContent.toString());

問題解決了，現在我收到了我想要的和我應該做的。唯一剩下的是，爲什麼SSL和NONSSL消息內容有區別？也許防病毒問題？

感謝您的幫助和關注。

祝您有美好的一天。
