我開發了一個小型控制檯應用程序來測試EWS StreamingSubscriptions/Notifications。過去我們使用推送通知,但理論上,在使用StreamingNotifications時,我應該能夠避免創建監聽器http端點及其所有問題(防火牆等)。StreamingNotifications不適用於Office 365/Exchange Online
所以,從我的本地機器;我這樣做:
static void Main(string[] args)
{
if (String.IsNullOrEmpty(ConfigurationManager.AppSettings["PrimaryLabUserId"]))
{
throw new ArgumentNullException("Please provide a value for PrimaryLabUserId in app.config");
}
_primaryLabUserId = ConfigurationManager.AppSettings["PrimaryLabUserId"];
string ServiceAccountName = ConfigurationManager.AppSettings["ExchangeServiceAccountName"];
string ServiceAccountPassword = ConfigurationManager.AppSettings["ExchangeServiceAccountPassword"];
_service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
_service.Credentials = new WebCredentials(ServiceAccountName, ServiceAccountPassword);
_service.AutodiscoverUrl(_primaryLabUserId, (x) => true);
_ewsUrl = _service.Url.AbsoluteUri;
var _connection = new StreamingSubscriptionConnection(_service, 30);
var sub = SubscribeForStreamingNotifications();
_connection.AddSubscription(sub);
_connection.OnDisconnect +=
new StreamingSubscriptionConnection.SubscriptionErrorDelegate(OnDisconnect);
// set up subscriptions here.
_connection.OnNotificationEvent +=
new StreamingSubscriptionConnection.NotificationEventDelegate(OnNewMail);
_connection.Open();
Console.WriteLine("Listening streaming...");
Console.ReadLine();
}
public static StreamingSubscription SubscribeForStreamingNotifications()
{
var folderIds = new List<FolderId>()
{
WellKnownFolderName.Inbox,
WellKnownFolderName.Calendar
};
var eventTypes = new List<EventType>();
eventTypes.Add(EventType.NewMail);
eventTypes.Add(EventType.Deleted);
eventTypes.Add(EventType.Moved);
eventTypes.Add(EventType.Created);
eventTypes.Add(EventType.Modified);
return _service.SubscribeToStreamingNotifications(folderIds, eventTypes.ToArray());
}
private static void OnNewMail(object sender, NotificationEventArgs args)
{
var test = args;
Console.WriteLine("Incoming");
}
認購初始化OK,但是當我發送新郵件到LabUser沒有任何反應。通知事件不會觸發。我嘗試pushnotifications一樣,它正在工作(在另一臺服務器上有一個公共http端點用於交換回叫)。 我想知道這可能與我的本地機器有什麼關係。
