Supporto per il comando IMAP IDLE e le estensioni

Supporto per il comando IMAP Idle

Aspose.Email API ImapClient fornisce la capacità di aprire una connessione al server e attendere l’arrivo di un messaggio email. Questo consente di evitare di interrogare ripetutamente il server per le email in arrivo. Il seguente frammento di codice mostra come supportare il comando IMAP Idle.

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
// Connect and log in to IMAP
ImapClient client = new ImapClient("imap.domain.com", "username", "password");

client.startMonitoring(new ImapMonitoringEventHandler() {
    public void invoke(Object sender, ImapMonitoringEventArgs e) {
        System.out.println(e.getNewMessages().length);
        System.out.println(e.getDeletedMessages().length);
    }
});
client.stopMonitoring("Inbox");

Supporto per le estensioni IMAP

L’API Aspose.Email fornisce il supporto per le estensioni IMAP. Attualmente le seguenti estensioni IMAP sono supportate dall’API. Queste estensioni IMAP non sono supportate da tutti i server.

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
final ImapClient client = new ImapClient("imap.gmail.com", 993, "username", "password");
try {
    // Set SecurityOptions
    client.setSecurityOptions(SecurityOptions.Auto);
    System.out.println(client.getIdSupported());

    ImapIdentificationInfo serverIdentificationInfo1 = client.introduceClient();
    ImapIdentificationInfo serverIdentificationInfo2 = client.introduceClient(ImapIdentificationInfo.getDefaultValue());

    // Display ImapIdentificationInfo properties
    System.out.println(serverIdentificationInfo1.toString() + serverIdentificationInfo2.toString());
    System.out.println(serverIdentificationInfo1.getName());
    System.out.println(serverIdentificationInfo1.getVendor());
    System.out.println(serverIdentificationInfo1.getSupportUrl());
    System.out.println(serverIdentificationInfo1.getVersion());
} finally {
    if (client != null)
        client.dispose();
}

Comando IMAP4 Extended List

Il seguente frammento di codice mostra come utilizzare il comando extended list di IMAP4.

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
final ImapClient client = new ImapClient("imap.gmail.com", 993, "username", "password");
try {
    ImapFolderInfoCollection folderInfoCol = client.listFolders("*");
    System.out.println("Extended List Supported: " + client.getExtendedListSupported());
    for (ImapFolderInfo folderInfo : (Iterable<ImapFolderInfo>) folderInfoCol) {
        if (folderInfo.getName().equals("[Gmail]/All Mail"))
            System.out.println("Has Children: " + folderInfo.hasChildren());
        if (folderInfo.getName().equals("[Gmail]/Bin"))
            System.out.println("Bin has children? " + folderInfo.hasChildren());
        if (folderInfo.getName().equals("[Gmail]/Drafts"))
            System.out.println("Drafts has children? " + folderInfo.hasChildren());
        if (folderInfo.getName().equals("[Gmail]/Important"))
            System.out.println("Important has Children? " + folderInfo.hasChildren());
        if (folderInfo.getName().equals("[Gmail]/Sent Mail"))
            System.out.println("Sent Mail has Children? " + folderInfo.hasChildren());
        if (folderInfo.getName().equals("[Gmail]/Spam"))
            System.out.println("Spam has Children? " + folderInfo.hasChildren());
        if (folderInfo.getName().equals("[Gmail]/Starred"))
            System.out.println("Starred has Children? " + folderInfo.hasChildren());
    }
} finally {
    if (client != null)
        client.dispose();
}
