Bekerja dengan Item Kalender di Server Exchange

Mengirim Permintaan Pertemuan

Artikel ini menunjukkan cara mengirim permintaan pertemuan ke beberapa penerima menggunakan Exchange Web Services dan Aspose.Email.

  1. Buat permintaan pertemuan menggunakan kelas Appointment dan atur lokasi, waktu, serta peserta.
  2. Buat instance kelas MailMessage dan atur janji menggunakan metode MailMessage.addAlternateView().
  3. Hubungkan ke Server Exchange dan kirim permintaan pertemuan menggunakan metode send(MailMessage).

The EWSClient kelas dapat digunakan untuk terhubung ke Server Exchange dengan dukungan Exchange Web Services (EWS). Agar ini berfungsi, server harus Exchange Server 2007 atau lebih baru. Potongan kode berikut menunjukkan cara menggunakan EWS untuk mengirim permintaan pertemuan.

try {
    // Create instance of IEWSClient class by giving credentials
    IEWSClient client = EWSClient.getEWSClient("https://outlook.office365.com/ews/exchange.asmx", "testUser", "pwd", "domain");

    Calendar c = Calendar.getInstance();
    c.add(Calendar.HOUR_OF_DAY, 1);
    Date startTime = c.getTime();
    c.add(Calendar.MINUTE, 90);
    Date endTime = c.getTime();

    // Create the meeting request
    Appointment app = new Appointment("meeting request", startTime, endTime, MailAddress.to_MailAddress("administrator@test.com"),
            MailAddressCollection.to_MailAddressCollection("bob@test.com"));
    app.setSummary("meeting request summary");
    app.setDescription("description");

    c = Calendar.getInstance();
    c.add(Calendar.DATE, 5);
    RecurrencePattern pattern = new DailyRecurrencePattern(c.getTime());
    app.setRecurrence(pattern);

    // Create the message and set the meeting request
    MailMessage msg = new MailMessage();
    msg.setFrom(MailAddress.to_MailAddress("administrator@test.com"));
    msg.setTo(MailAddressCollection.to_MailAddressCollection("bob@test.com"));
    msg.isBodyHtml(true);
    msg.setHtmlBody("<h3>HTML Heading</h3><p>Email Message detail</p>");
    msg.setSubject("meeting request");
    msg.addAlternateView(app.requestApointment(0));

    // send the appointment
    client.send(msg);
    System.out.println("Appointment request sent");
} catch (java.lang.RuntimeException ex) {
    System.out.println(ex.getMessage());
}

Bekerja dengan Item Kalender menggunakan EWS

Aspose.Email menyediakan kemampuan untuk menambahkan, memperbarui, dan membatalkan janji menggunakan klien Exchange Web Service (EWS). The IEWSClients createAppointment, updateAppointment, dan cancelAppointment metode memungkinkan memanipulasi item kalender menggunakan EWS. Artikel ini menyediakan contoh kode terperinci tentang bekerja dengan item Kalender. Contoh kode berikut menunjukkan cara:

  1. Buat sebuah janji.
  2. Perbarui janji.
  3. Hapus/Batalkan janji.
IEWSClient client = EWSClient.getEWSClient("https://outlook.office365.com/ews/exchange.asmx", "your.username", "your.Password");
Calendar c = Calendar.getInstance();
c.set(Calendar.MINUTE, 0);
c.set(Calendar.SECOND, 0);
c.set(Calendar.MILLISECOND, 0);
Date startTime = c.getTime();
c.add(Calendar.HOUR_OF_DAY, 1);
Date endTime = c.getTime();
String timeZone = "America/New_York";

Appointment app = new Appointment("Room 112", startTime, endTime, MailAddress.to_MailAddress("organizeraspose-email.test3@domain.com"),
        MailAddressCollection.to_MailAddressCollection("attendee@gmail.com"));
app.setTimeZone(timeZone);
app.setSummary("NETWORKNET-34136" + UUID.randomUUID().toString());
app.setDescription("NETWORKNET-34136 Exchange 2007/EWS: Provide support for Add/Update/Delete calendar items");

String uid = client.createAppointment(app);
Appointment fetchedAppointment1 = client.fetchAppointment(uid);
app.setLocation("Room 115");
app.setSummary("New summary for " + app.getSummary());
app.setDescription("New Description");
client.updateAppointment(app);

Appointment[] appointments1 = client.listAppointments();
System.out.println("Total Appointments: " + appointments1.length);
Appointment fetchedAppointment2 = client.fetchAppointment(uid);
System.out.println("Summary: " + fetchedAppointment2.getSummary());
System.out.println("Location: " + fetchedAppointment2.getLocation());
System.out.println("Description: " + fetchedAppointment2.getDescription());
client.cancelAppointment(app);
Appointment[] appointments2 = client.listAppointments();
System.out.println("Total Appointments: " + appointments2.length);

Kembalikan Item Kalender Berulang dalam Rentang Tanggal yang Ditentukan

Aspose.Email EWSClient mendukung pengembalian item kalender berulang dalam rentang yang ditentukan oleh StartDate dan EndDate. AppointmentQueryBuilder.setCalendarView(Date startDate, Date endDate, int maxEntriesReturned) metode, jika CalendarView ditentukan, mengembalikan daftar item kalender tunggal dan kejadian item kalender berulang dalam rentang yang ditentukan oleh StartDate dan EndDate. Parameter maxEntriesReturned menggambarkan jumlah hasil maksimum. (Nilai <= 0 untuk semua hasil).

ExchangeQueryBuilder builder = new ExchangeQueryBuilder();
builder.getAppointment().setCalendarView(startDate, endDate, -1);

Appointment[] appointments = client.listAppointments(builder.getQuery());

Menyebutkan Janji dengan Dukungan Paging

Metode ListAppointments yang disediakan oleh IEWSClient API mengambil daftar lengkap janji dari server Exchange. Ini mungkin memerlukan waktu jika ada banyak janji di Server Exchange. API menyediakan metode overload dari listAppointments metode yang memberikan dukungan paging pada operasi. Ini dapat digunakan dalam kombinasi berbeda dengan fitur query juga. Metode overload berikut tersedia untuk menyebutkan janji dari Server Exchange dengan dukungan Paging.

  • AppointmentCollection IEWSClient.listAppointments(int itemsPerPage).
  • AppointmentCollection IEWSClient.listAppointments(String folderUri, int itemsPerPage).
  • AppointmentCollection IEWSClient.listAppointments(MailQuery query, int itemsPerPage).
  • AppointmentCollection IEWSClient.listAppointments(String folderUri, MailQuery query, int itemsPerPage).
  • AppointmentCollection IEWSClient.listAppointments(int itemsPerPage, int itemOffset).
  • AppointmentCollection IEWSClient.listAppointments(String folderUri, int itemsPerPage, int itemOffset).
  • AppointmentCollection IEWSClient.listAppointments(MailQuery query, int itemsPerPage, int itemOffset).
  • AppointmentCollection IEWSClient.listAppointments(String folderUri, MailQuery query, int itemsPerPage, int itemOffset).

Potongan kode berikut menunjukkan cara menyebutkan janji dengan dukungan paging.

        IEWSClient client = EWSClient.getEWSClient("exchange.domain.com", "username", "password");
        try {
            try {
                Appointment[] appts = client.listAppointments();
                System.out.println(appts.length);

                Calendar c = Calendar.getInstance();
                c.set(Calendar.MINUTE, 0);
                c.set(Calendar.SECOND, 0);
                c.set(Calendar.MILLISECOND, 0);

                int appNumber = 10;
                Map<String, Appointment> appointmentsDict = new HashMap<String, Appointment>();
                for (int i = 0; i < appNumber; i++) {
                    c.set(Calendar.HOUR_OF_DAY, i + 1);
                    Date startTime = c.getTime();
                    c.set(Calendar.HOUR_OF_DAY, i + 2);
                    Date endTime = c.getTime();

                    String timeZone = "America/New_York";
                    Appointment appointment = new Appointment("Room 112", startTime, endTime, MailAddress.to_MailAddress("from@domain.com"),
                            MailAddressCollection.to_MailAddressCollection("to@domain.com"));
                    appointment.setTimeZone(timeZone);
                    appointment.setSummary("NETWORKNET-35157_3 - " + UUID.randomUUID().toString());
                    appointment.setDescription("EMAILNET-35157 Move paging parameters to separate class");
                    String uid = client.createAppointment(appointment);
                    appointmentsDict.put(uid, appointment);
                }
                AppointmentCollection totalAppointmentCol = AppointmentCollection.to_AppointmentCollection(client.listAppointments());

                ///// LISTING APPOINTMENTS WITH PAGING SUPPORT ///////
                int itemsPerPage = 2;
                List<AppointmentPageInfo> pages = new ArrayList<AppointmentPageInfo>();
                AppointmentPageInfo pagedAppointmentCol = client.listAppointmentsByPage(itemsPerPage);
                System.out.println(pagedAppointmentCol.getItems().size());
                pages.add(pagedAppointmentCol);
                while (!pagedAppointmentCol.getLastPage()) {
                    pagedAppointmentCol = client.listAppointmentsByPage(itemsPerPage, pagedAppointmentCol.getPageOffset() + 1);
                    pages.add(pagedAppointmentCol);
                }
                int retrievedItems = 0;
                // foreach to while statements conversion
                for (AppointmentPageInfo folderCol : pages) {
                    retrievedItems += folderCol.getItems().size();
                }
            } finally {
            }
        } finally {
            client.dispose();
        }

Menambahkan Acara ke Folder Kalender Sekunder di Server Exchange

API Aspose.Email memungkinkan Anda membuat folder Kalender sekunder di Server Exchange menggunakan IEWSClient. Janjian kemudian dapat ditambahkan, diperbarui, atau dibatalkan dari kalender sekunder menggunakan createAppointment, updateAppointment dan cancelAppointment metode. Metode API dan properti berikut digunakan dalam contoh kode di bawah untuk menunjukkan fungsi fitur ini. Harap dicatat bahwa fitur ini didukung oleh Aspose.Email untuk Java 6.5.0 ke atas.

  • Metode IEWSClient.cancelAppointment(Appointment, String).
  • Metode IEWSClient.cancelAppointment(String, String).
  • Metode IEWSClient.createAppointment(Appointment, String).
  • Metode IEWSClient.createFolder(String, String, ExchangeFolderPermissionCollection, String).
  • Metode IEWSClient.fetchAppointment(String, String).
  • Metode IEWSClient.updateAppointment(Appointment, String).
  • Properti IEWSClient.CurrentCalendarFolderUri.

Potongan kode berikut menunjukkan cara menambahkan acara ke folder kalender sekunder di server exchange.

IEWSClient client = EWSClient.getEWSClient("https://outlook.office365.com/ews/exchange.asmx", "your.username", "your.Password");
try {
    try {
        // Create an appointmenta that will be added to secondary calendar folder

        Calendar c = Calendar.getInstance();
        c.set(Calendar.MINUTE, 0);
        c.set(Calendar.SECOND, 0);
        c.set(Calendar.MILLISECOND, 0);
        Date startTime = c.getTime();
        c.add(Calendar.HOUR_OF_DAY, 1);
        Date endTime = c.getTime();

        String timeZone = "America/New_York";

        Appointment[] listAppointments;
        Appointment appointment = new Appointment("Room 121", startTime, endTime, MailAddress.to_MailAddress("from@domain.com"),
                MailAddressCollection.to_MailAddressCollection("attendee@domain.com"));
        appointment.setTimeZone(timeZone);
        appointment.setSummary("EMAILNET-35198 - " + UUID.randomUUID().toString());
        appointment.setDescription("EMAILNET-35198 Ability to add event to Secondary Calendar of Office 365");

        // Verify that the new folder has been created
        ExchangeFolderInfoCollection calendarSubFolders = client.listSubFolders(client.getMailboxInfo().getCalendarUri());

        String getfolderName;
        String setFolderName = "New Calendar";
        boolean alreadyExits = false;

        // Verify that the new folder has been created already exits or not

        for (int i = 0; i < calendarSubFolders.size(); i++) {
            getfolderName = calendarSubFolders.get_Item(i).getDisplayName();

            if (getfolderName.equals(setFolderName)) {
                alreadyExits = true;
            }
        }

        if (alreadyExits) {
            System.out.println("Folder Already Exists");
        } else {
            // Create new calendar folder
            client.createFolder(client.getMailboxInfo().getCalendarUri(), setFolderName, null, "IPF.Appointment");

            System.out.println(calendarSubFolders.size());

            // Get the created folder URI
            String newCalendarFolderUri = calendarSubFolders.get_Item(0).getUri();

            // appointment api with calendar folder uri
            // Create
            client.createAppointment(appointment, newCalendarFolderUri);
            appointment.setLocation("Room 122");
            // update
            client.updateAppointment(appointment, newCalendarFolderUri);
            // list
            listAppointments = client.listAppointments(newCalendarFolderUri);

            // list default calendar folder
            listAppointments = client.listAppointments(client.getMailboxInfo().getCalendarUri());

            // Cancel
            client.cancelAppointment(appointment, newCalendarFolderUri);
            listAppointments = client.listAppointments(newCalendarFolderUri);

            // appointment api with context current calendar folder uri
            client.setCurrentCalendarFolderUri(newCalendarFolderUri);
            // Create
            client.createAppointment(appointment);
            appointment.setLocation("Room 122");
            // update
            client.updateAppointment(appointment);
            // list
            listAppointments = client.listAppointments();

            // list default calendar folder
            listAppointments = client.listAppointments(client.getMailboxInfo().getCalendarUri());

            // Cancel
            client.cancelAppointment(appointment);
            listAppointments = client.listAppointments();

        }
    } finally {
    }
} finally {
    client.dispose();
}

Berbagi Undangan Kalender

Server Microsoft Exchange menyediakan kemampuan untuk berbagi kalender dengan mengirim undangan kalender ke pengguna lain yang terdaftar pada server Exchange yang sama. API Aspose.Email menyediakan kemampuan yang sama dengan memungkinkan berbagi kalender menggunakan API EWS.

final IEWSClient client = EWSClient.getEWSClient("https://outlook.office365.com/ews/exchange.asmx", "testUser", "pwd", "domain");
try {
    // delegate calendar access permission
    ExchangeDelegateUser delegateUser = new ExchangeDelegateUser("sharingfrom@domain.com", ExchangeDelegateFolderPermissionLevel.NotSpecified);
    delegateUser.getFolderPermissions().setCalendarFolderPermissionLevel(ExchangeDelegateFolderPermissionLevel.Reviewer);
    client.delegateAccess(delegateUser, "sharingfrom@domain.com");

    // Create invitation
    MapiMessage mapiMessage = client.createCalendarSharingInvitationMessage("sharingfrom@domain.com");
    MailConversionOptions options = new MailConversionOptions();
    options.setConvertAsTnef(true);
    MailMessage mail = mapiMessage.toMailMessage(options);
    client.send(mail);
} finally {
    client.dispose();
}

Mengambil Informasi Atribut Ekstended dari Item Kalender

IEWSClient client = EWSClient.getEWSClient("https://exchange.office365.com/Exchange.asmx", "username", "password");

java.util.List<String> uriList = java.util.Arrays.asList(client.listItems(client.getMailboxInfo().getCalendarUri()));

// Define the Extended Attribute Property Descriptor for searching purpose
// In this case, we have a K1 Long named property for Calendar item
UUID uuid = UUID.fromString("00020329-0000-0000-C000-000000000046");
PropertyDescriptor propertyDescriptor = new PidNamePropertyDescriptor("K1", PropertyDataType.Integer32, uuid);

java.util.List<PropertyDescriptor> propertyDescriptors = java.util.Arrays.asList(new PropertyDescriptor[] { propertyDescriptor });
IGenericList<MapiCalendar> mapiCalendarList = client.fetchMapiCalendar(uriList, propertyDescriptors);

for (MapiCalendar cal : mapiCalendarList) {
    for (MapiNamedProperty namedProperty : (Iterable<MapiNamedProperty>) cal.getNamedProperties().getValues()) {
        System.out.println(namedProperty.getNameId() + " = " + namedProperty.getInt32());
    }
}
