Question

使用Notifications REST API和JavaScript，我们通过FCM订阅了渐进式Web应用，然后调用registrations端点在ANH上注册

注册完成正常，我们可以在具有正确平台和已填充PNS标识符的集线器上看到注册

当我们尝试向所有注册的设备发送测试消息时，我们在ANH中收到以下错误消息

从令牌提供者获得的令牌是错误的

我们尝试发送Firebase返回的整个endpoint对象，仅发送subscriptionId和其他各种组合

错误消息是否表示我们已使用错误的密钥对进行了订阅，或者令牌的格式不正确？没有地方显示GcmRegistrationId格式向注册端点注册时的示例

您可以使用以下方法注册设备：

如果是GCM，请遵循以下方法：

将Nuget包用于通知中心。

对于DeviceRegistration.cs

 public class DeviceRegistration
    {
        public string Platform { get; set; } 
        public string Handle { get; set; }
        public string[] Tags { get; set; }
    }

对于NotificationClient.cs

 using Microsoft.Azure.NotificationHubs; // Namespace to be used

// Use below method to get registrationID

 public async Task<string> GetRegistrationID(NotificationHubClient Hub, string handle = null)
        {
            string newRegistrationId = null;

            // make sure there are no existing registrations for this push handle (used for iOS and Android)
            if (handle != null)
            {
                var registrations = await Hub.GetRegistrationsByChannelAsync(handle, 100);
                foreach (RegistrationDescription registration in registrations)
                {
                    if (newRegistrationId == null)
                    {
                        newRegistrationId = registration.RegistrationId;
                    }
                    else
                    {
                        await Hub.DeleteRegistrationAsync(registration);
                    }
                }
            }

            if (newRegistrationId == null)
                newRegistrationId = await Hub.CreateRegistrationIdAsync();

            return newRegistrationId;
        }

// Use below method to upsert registration to azure

 public async Task UpsertRegistration(string registrationid, DeviceRegistration deviceUpdate, NotificationHubClient Hub)
            {
    string[] tags = { "abc","def" }; // These are used to send notifications
     DeviceRegistration deviceRegistration = new DeviceRegistration
                    {
                        Handle = newDeviceToken, // Device token given by Firebase
                        Platform = "gcm", // Specify gcm for android and "apns" for ios  
                        Tags = tags
                    };

                RegistrationDescription registration
                         = new GcmRegistrationDescription(deviceRegistration.Handle);



                registration.RegistrationId = registrationid;

                // add check if user is allowed to add these tags
                registration.Tags = new HashSet<string>();
                foreach (string tag in deviceUpdate.Tags)
                {
                    registration.Tags.Add(tag);
                }

               await Hub.CreateOrUpdateRegistrationAsync(registration);           
            }
