azure - Xamarin.iOS 无法在 iOS 13.1.2 中向 Azure 通知中心注册

Question

我已经处理这个问题几天了。

昨天发布了 Xamarin.Azure.NotificationHubs.iOS NuGet 包的更新。

nuget 包的 Github 链接上的示例中注册通知中心的方式现在与 Microsoft Azure 文档中的方式不同。

我缩小了我认为的问题范围，以获得正确的连接字符串。 错误发生在这一行: var hub = new SBNotificationHub(connectionString,HubName);

------注册集线器的文档方式(“旧”方式，仅适用于我的 iOS 12):

public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
    Hub = new SBNotificationHub(Constants.ListenConnectionString, Constants.NotificationHubName);

    Hub.UnregisterAllAsync (deviceToken, (error) => {
        if (error != null)
        {
            System.Diagnostics.Debug.WriteLine("Error calling Unregister: {0}", error.ToString());
            return;
        }

        NSSet tags = null; // create tags if you want
        Hub.RegisterNativeAsync(deviceToken, tags, (errorCallback) => {
            if (errorCallback != null)
                System.Diagnostics.Debug.WriteLine("RegisterNativeAsync error: " + errorCallback.ToString());
        });
    });
}

------昨天更新了 Xamarin.Azure.NotificationHubs.iOS nuget 包的 Github 示例代码:

public override void RegisteredForRemoteNotifications (UIApplication application, NSData deviceToken)
        {
            // Connection string from your azure dashboard
            var cs = SBConnectionString.CreateListenAccess(
                new NSUrl("sb://" + HUB_NAME + "-ns.servicebus.windows.net/"),
                HUB_LISTEN_SECRET);

            // Register our info with Azure
            var hub = new SBNotificationHub (cs, HUB_NAME);
            hub.RegisterNative (deviceToken, null, err => {

                if (err != null) {
                    Console.WriteLine("Error: " + err.Description);
                    homeViewController.RegisteredForNotifications ("Error: " + err.Description);
                } else  {
                    Console.WriteLine("Success");
                    homeViewController.RegisteredForNotifications ("Successfully registered for notifications");
                }
            });
        }

或者来自不同 azure 文档的相同代码也在 13 小时前更新:

public override void RegisteredForRemoteNotifications (UIApplication app, NSData deviceToken)
{
    // Connection string from your azure dashboard
    var cs = SBConnectionString.CreateListenAccess(
        new NSUrl("sb://yourservicebus-ns.servicebus.windows.net/"),
        "YOUR-KEY");

    // Register our info with Azure
    var hub = new SBNotificationHub (cs, "your-hub-name");
    hub.RegisterNativeAsync (deviceToken, null, err => {
        if (err != null)
            Console.WriteLine("Error: " + err.Description);
        else
            Console.WriteLine("Success");
    });
}

我似乎无法正确创建连接字符串。 在 Azure 门户上，“通知中心访问策略”选项卡中的连接字符串如下所示:

Endpoint=sb://namespace.servicebus.windows.net/;SharedAccessKeyName=ListenSharedPolicyName;SharedAccessKey=AccessKey

如何正确创建连接字符串？哪个是服务总线部分，哪个是关键(或 secret )部分，为什么会有“-ns”部分。

迄今为止最好的尝试是创建如下连接字符串:

public override void RegisteredForRemoteNotifications(
            UIApplication application, NSData deviceToken)
        {

            try
            {
                var cs = SBConnectionString.CreateListenAccess(
                new NSUrl("sb://" + AppConstants.HUBNAME + "-ns.servicebus.windows.net/"),
                AppConstants.AccessKey);

                var hub = new SBNotificationHub(cs, AppConstants.DEV3_HUBNAME);

                // await hub.UnregisterAllAsync(deviceToken);

                hub.RegisterNative(deviceToken, null, err => {

                    if (err != null)
                    {
                        Console.WriteLine("Error: " + err.Description);
                        //homeViewController.RegisteredForNotifications("Error: " + err.Description);
                    }
                    else
                    {
                        Console.WriteLine("Success");
                        //homeViewController.RegisteredForNotifications("Successfully registered for notifications");
                    }
                });
            }
            catch(Exception ex)
            {
                Debug.WriteLine(ex.Message);
            }

但是我曾经遇到过这个错误:

Could not initialize an instance of the type 'Foundation.NSUrl': the native 'initWithString:' method returned nil. It is possible to ignore this condition by setting ObjCRuntime.Class.ThrowOnInitFailure to false.

大多数时候是这样的:

如果有人遇到同样的问题，我就完成了这项工作，下面是工作代码。 与 NuGet 包一起使用:

Xamarin.Azure.NotificationHubs.iOS v2.0.4

  try
     {
           AzureNotifHub = new SBNotificationHub(HUB_LISTENSHARED_CONNSTRING, HUBNAME);

          // update registration with Azure Notification Hub
           await AzureNotifHub.UnregisterAllAsync(deviceToken);


           var tags = new NSSet(AppConstants.IOSSUBSCRIPTIONTAGS.ToArray());
           await AzureNotifHub.RegisterNativeAsync(deviceToken, tags);

           var templateExpiration = DateTime.Now.AddDays(120).ToString(System.Globalization.CultureInfo.CreateSpecificCulture("en-US"));
                    await AzureNotifHub.RegisterTemplateAsync(deviceToken, "defaultTemplate", AppConstants.IOS_APNS_TEMPLATE_BODY, templateExpiration, tags);
      }
      catch (Exception ex)
      {
           Debug.WriteLine(ex.Message);
      }
