我有一个工作的Azure应用服务连接到配置了GCM和APNS的通知中心。它在两个平台上都运行了好几个月。
我现在已经开启了应用服务中的身份验证，并配置了google和facebook。这些也可以很好地工作，并且正确的访问权限适用于简单的表格。
但是，自启用身份验证以来，移动应用程序中的设备注册现已失败。
以下是我在应用服务（NodeJS）上遇到的错误：
System.NullReferenceException: Object reference not set to an instance of an object.

我能够将通知（使用测试发送和通过我的服务器推送代码）发送到现有注册，我只是无法创建新的注册。
当我关闭身份验证时，它会再次正常工作。
在此身份验证方案中，是否需要在通知中心中手动创建注册？
我不知道自己哪里出错了，所以任何帮助都会非常感激。

作为导致问题的RegisterAsync的替代方案;您可以使用HttpClient调用来PUT Notification Hub安装。以下代码将在Android上设置安装，例如：
public async Task RegisterForPushNotifications(MobileServiceClient client)
{
if (GcmClient.IsRegistered(RootView))
{
try
{
var registrationId = GcmClient.GetRegistrationId(RootView);
//var push = client.GetPush();
//await push.RegisterAsync(registrationId);
var installation = new DeviceInstallation
{
InstallationId = client.InstallationId,
Platform = "gcm",
PushChannel = registrationId
};
// Set up tags to request
installation.Tags.Add("topic:Sports");
// Set up templates to request
PushTemplate genericTemplate = new PushTemplate
{
Body = "{\"data\":{\"message\":\"$(messageParam)\"}}"
};
// Register with NH
var response = await client.InvokeApiAsync<DeviceInstallation, DeviceInstallation>(
$"/push/installations/{client.InstallationId}",
installation,
HttpMethod.Put,
new Dictionary<string, string>());
}
catch (Exception ex)
{
Log.Error("DroidPlatformProvider", $"Could not register with NH: {ex.Message}");
}
}
else
{
Log.Error("DroidPlatformProvider", $"Not registered with GCM");
}
}
DeviceInstallation类看起来像这样：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Newtonsoft.Json;
namespace TaskList.Abstractions
{
public class DeviceInstallation
{
public DeviceInstallation()
{
Tags = new List<string>();
Templates = new Dictionary<string, PushTemplate>();
}
[JsonProperty(PropertyName = "installationId")]
public string InstallationId { get; set; }
[JsonProperty(PropertyName = "platform")]
public string Platform { get; set; }
[JsonProperty(PropertyName = "pushChannel")]
public string PushChannel { get; set; }
[JsonProperty(PropertyName = "tags")]
public List<string> Tags { get; set; }
[JsonProperty(PropertyName = "templates")]
public Dictionary<string, PushTemplate> Templates { get; set; }
}
public class PushTemplate
{
public PushTemplate()
{
Tags = new List<string>();
Headers = new Dictionary<string, string>();
}
[JsonProperty(PropertyName = "body")]
public string Body { get; set; }
[JsonProperty(PropertyName = "tags")]
public List<string> Tags { get; set; }
[JsonProperty(PropertyName = "headers")]
public Dictionary<string, string> Headers { get; set; }
}
}
将RegisterForPushNotifications（）方法放在特定于平台的代码中。 DeviceInstallation可以在PCL中。
