Azure 通知中心 - “从令牌提供程序获取的令牌错误”

Question

使用 Notifications REST API 和 JavaScript，我们通过 FCM 订阅我们的 Progressive Web App，然后调用registrations 端点在我们的 ANH 上注册

注册完成正常，我们可以在我们的集线器上使用正确的平台和填充的 PNS 标识符看到注册

当我们尝试向所有注册设备发送测试消息时，我们在 ANH 中收到以下错误

从令牌提供者获取的令牌错误

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

错误信息是否意味着我们使用了错误的密钥对进行了订阅，或者令牌的格式不正确？在注册端点注册时，没有任何地方显示GcmRegistrationId 格式的示例

您可以使用以下方法注册您的设备：

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);           
            }
