使用Azure通知中心的InvalidDataContractException

我几乎要复制有关使用Windows Azure通知中心发送推送通知的文章:http://www.windowsazure.com/en-us/manage/services/notification-hubs/notify-users-aspnet/

不幸的是,当我尝试使用 CreateWindowsNativeRegistrationAsync 方法时,我遇到了在Microsoft.ServiceBus 中发生的 InvalidDataContractException。我无法看到我的代码与示例有任何区别,而且我没有进行序列化。 (大约一半的页面):

更新:将相同的代码放在控制台应用中,使用" http://test.com"因为channelURI导致异常并出现以下错误:"不支持的频道uri:http://test.com"

public async Task<bool> NotificationRegistration(User user, NotificationRegistration reg)
{
  var regs = await hubClient.GetRegistrationsByTagAsync(reg.InstallationID, 100);

  bool updated = false;
  bool firstRegistration = true;
  RegistrationDescription registration = null;

  foreach (var regDescription in regs)
  {
    if (firstRegistration)
    {
      regDescription.Tags = new HashSet<string>() { reg.InstallationID, user._id };

      // We need to handle each platform separately.
      switch (reg.Platform)
      {
        case "WP":
          var winReg = regDescription as WindowsRegistrationDescription;
          winReg.ChannelUri = new Uri(reg.ChannelUri);
          registration = await hubClient.UpdateRegistrationAsync(winReg);
          break;
      }
      updated = true;
      firstRegistration = false;
    }
    else
    {
      // We shouldn't have any extra registrations; delete if we do.
      await hubClient.DeleteRegistrationAsync(regDescription);
    }
  }

  // Create a new registration.
  if (!updated)
  {
    switch (reg.Platform)
    {
        case "WP":
        //always fails here
        registration = await hubClient.CreateWindowsNativeRegistrationAsync(reg.ChannelUri, new string [] { reg.InstallationID, user._id });
            break;
    }
  }
}

任何有关我出错的指导都将非常感谢....

答案 0 :(得分:1)

从平台看,您似乎正在使用WindowsPhone。如果是这种情况,则必须创建MpnsRegistrationDescription。因此,您可能会收到异常,因为CHANnelURI不是WIndows Store CHannelURI。
