Question

我对此很陌生。 android的例子来自 GetStartedFirebase

以下是步骤：

1）我将android安装到手机

2）我按照这个例子来创建我的web api HTTPS // docs.microsoft.com / EN-US /天青/通知-集线器/通知-集线器-ASPNET-后端-GCM-机器人推到用户谷歌通知

3）我注释掉AuthenticationTestHandler类

4）我从小提琴中调用以下代码

DeviceRegistration对象

{
  "Platform": "gcm",
  "Handle": "regid i get from android",
  "Tags": [
    "1",
    "2"
  ]
}

//这将创建或更新指定ID

的注册（使用提供的channelURI）

      public async Task<HttpResponseMessage> Put(string id, DeviceRegistration deviceUpdate)
    {
        RegistrationDescription registration = null;
        switch (deviceUpdate.Platform)
        {
            case "mpns":
                registration = new MpnsRegistrationDescription(deviceUpdate.Handle);
                break;
            case "wns":
                registration = new WindowsRegistrationDescription(deviceUpdate.Handle);
                break;
            case "apns":
                registration = new AppleRegistrationDescription(deviceUpdate.Handle);
                break;
            case "gcm":
                registration = new GcmRegistrationDescription(deviceUpdate.Handle);
                break;
            default:
                throw new HttpResponseException(HttpStatusCode.BadRequest);
        }

        registration.RegistrationId = id;

        var username = "test";

        string[] userTag = new string[1];
        userTag[0] = "username:" + username;
        registration.Tags = new HashSet<string>(userTag);
        try
        {
            await hub.CreateOrUpdateRegistrationAsync(registration);
        }
        catch (MessagingException e)
        {
            ReturnGoneIfHubResponseIsGone(e);
        }

        return Request.CreateResponse(HttpStatusCode.OK);
    }

5）然后我打电话发送推送通知

http://localhost:4486/api/Notifications?pns=gcm&to_tag=test

public async Task<HttpResponseMessage> Post(string pns, [FromBody]string message, string to_tag)
{

    var user = "test";
    message = "msg";
    string[] userTag = new string[1];
    userTag[0] = "username:" + to_tag;     

    Microsoft.Azure.NotificationHubs.NotificationOutcome outcome = null;
    HttpStatusCode ret = HttpStatusCode.InternalServerError;

    switch (pns.ToLower())
    {
        case "wns":
            // Windows 8.1 / Windows Phone 8.1
            var toast = @"<toast><visual><binding template=""ToastText01""><text id=""1"">" +
                        "From " + user + ": " + message + "</text></binding></visual></toast>";
            outcome = await Notifications.Instance.Hub.SendWindowsNativeNotificationAsync(toast, userTag);
            break;
        case "apns":
            // iOS
            var alert = "{\"aps\":{\"alert\":\"" + "From " + user + ": " + message + "\"}}";
            outcome = await Notifications.Instance.Hub.SendAppleNativeNotificationAsync(alert, userTag);
            break;
        case "gcm":
            // Android
            var notif = "{ \"data\" : {\"message\":\"" + "From " + user + ": " + message + "\"}}";
            outcome = await Notifications.Instance.Hub.SendGcmNativeNotificationAsync(notif, userTag);
            break;
    }

    if (outcome != null)
    {
        if (!((outcome.State == Microsoft.Azure.NotificationHubs.NotificationOutcomeState.Abandoned) ||
            (outcome.State == Microsoft.Azure.NotificationHubs.NotificationOutcomeState.Unknown)))
        {
            ret = HttpStatusCode.OK;
        }
    }

    return Request.CreateResponse(ret);
}

没有返回任何错误，但我没有收到任何通知。

我尝试删除usertag，如下所示：

outcome = await Notifications.Instance.Hub.SendGcmNativeNotificationAsync(notif);

我可以收到通知。

为什么标签不起作用？

任何帮助表示感谢。

RtlDecodePointer

在API-MS-*中查看您的代码。如果它在那里它应该工作。

您可以查看http://pushtry.com

的测试通知

Answer 2

我很困惑 - 来自Fiddler的JSON表明注册有＆＃34; 1＆＃34;和＆＃34; 2＆＃34;标签，但你正在使用的代码中的任何地方＆＃34;用户名：test＆＃34;标签。你能从集线器获得这个注册并确保它有正确的标签吗？您可以使用GetRegistrationAsync<TRegistrationDescription>(String) [1]，GetRegistrationsByChannelAsync(String, Int32) [2]或GetAllRegistrationsAsync(Int32) [3]方法进行注册。

[1] https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.notificationhubs.notificationhubclient#Microsoft_Azure_NotificationHubs_NotificationHubClient_GetRegistrationAsync__1_System_String_

[2] https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.notificationhubs.notificationhubclient#Microsoft_Azure_NotificationHubs_NotificationHubClient_GetRegistrationsByChannelAsync_System_String_System_Int32_

[3] https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.notificationhubs.notificationhubclient#Microsoft_Azure_NotificationHubs_NotificationHubClient_GetAllRegistrationsAsync_System_Int32_

使用标记时，不会收到azure通知中心的通知
