我正在尝试在没有注册句柄的Android平台中发送推送通知。
https://azure.microsoft.com/en-us/updates/push-notification-hubs-batch-direct-send/ https://docs.microsoft.com/en-us/previous-versions/azure/reference/mt608572(v%3dazure.100)
我尝试使用NotificationHubClient.SendDirectNotificationAsync（notification，handle）方法，但出现错误。
{ “ Message”：“发生错误。”， “ ExceptionMessage”：“直接发送不支持模板通知”， “ ExceptionType”：“ System.ArgumentException”，
public class NotificationMessage : Microsoft.Azure.NotificationHubs.Notification
{
public NotificationMessage(IDictionary<string, string> additionalHeaders, string tag)
: base(additionalHeaders, tag)
{
}
protected override string PlatformType => "gcm";
protected override void OnValidateAndPopulateHeaders()
{
}
}
public async Task<HttpResponseMessage> DirectSend(string pns,string handle, [FromBody]string message)
{
Microsoft.Azure.NotificationHubs.NotificationOutcome outcome = null;
HttpStatusCode ret = HttpStatusCode.InternalServerError;
switch (pns.ToLower())
{
case "gcm":
NotificationMessage notificationMessage = new NotificationMessage(new Dictionary<string, string>(), string.Empty);
notificationMessage.Body = "{ \"data\" : {\"message\":\"" + "From AMS : " + message + "\"}}";
notificationMessage.ContentType = "application/json";
outcome = await Notifications.Instance.Hub.SendDirectNotificationAsync(notificationMessage, handle);
break;
}
if (outcome != null)
{
if (!((outcome.State == Microsoft.Azure.NotificationHubs.NotificationOutcomeState.Abandoned) ||
(outcome.State == Microsoft.Azure.NotificationHubs.NotificationOutcomeState.Unknown)))
{
ret = HttpStatusCode.OK;
}
}
return Request.CreateResponse(ret);
}
注意 Microsoft.Azure.NotificationHubs.Notification是Abstract类，因此我在NotificationMessage类中实现了该类并作为参数传递。我认为我的Abstract类实现不正确。
知道我做错了什么吗？
