Question

我正在开发使用WNS的小型Windows应用商店应用。我创建了命令行应用程序，它向WNS发送Toast消息。从控制台应用程序发送消息后，我的Windows应用商店没有从WNS获得任何推送通知。

情景：

启动Windows商店应用程序，该应用程序将带有令牌的URL存储到文件中，comman line appplication获取url并在向WNS发送Toast消息时使用它。
启动控制台应用程序，它从文件中获取url并将创建的消息发送到WNS。
我的win store应用程序未收到来自WNS的任何推送通知。

控制台应用程序成功通过身份验证过程。发送toast后，我收到了来自WNS的回复，其中包含以下标题：

X-WNS-DEVICECONNECTIONSTATUS：已连接

X-WNS-NOTIFICATIONSTATUS：已收到

X-WNS-STATUS：已收到

X-WNS-MSG-ID：41C38906780D2A8C

X-WNS-DEBUG-TRACE：DB3WNS4011132

内容长度：0

在那个方法之后，wnsManager_PushNotificationReceived没有触发。 Windows应用与商店相关联。

命令行应用程序中的代码：

    class Program
    {
        private static string secret = "Client secret";
        private static string SID = "Package Security Identifier (SID)";
        private static OAuthToken _token;
        private static string XmlToastTemplate = @"<toast launch="">
<visual lang=""en-US"">
<binding template=""ToastText01"">
<text id=""1"">Test message</text>
</binding>
</visual>
</toast>";
        private static Uri accesTokenuri = new Uri("https://login.live.com/accesstoken.srf");


        static void Main(string[] args)
        {
            if (_token == null)
            {
                CreateToken();
            }

            var message = String.Empty;
            while(true)
            {
                Console.WriteLine("Enter toast message");
                message = Console.ReadLine();
                if (message == "exit") break;
                else
                {
                    var uriWithToken = GetUriWithToken();
                    var wc = HttpWebRequest.Create(uriWithToken) as HttpWebRequest;
                    wc.Method = "POST";
                    wc.Headers.Add("X-WNS-Type", "wns/toast");
                    wc.Headers.Add("X-WNS-RequestForStatus", "true");
                    wc.Headers.Add("Authorization", String.Format("Bearer {0}", _token.AccessToken));
                    wc.ContentType = "text/xml";
                    var byteContent = Encoding.UTF8.GetBytes(XmlToastTemplate);
                    using (var requestStream = wc.GetRequestStream())
                    {
                        requestStream.Write(byteContent,0,byteContent.Length);
                    }

                    using (var response = wc.GetResponse() as HttpWebResponse)
                    {
                        if (response != null)
                        {
                            var statusCode = response.StatusCode;
                            Console.WriteLine(statusCode);
                        }
                    }

                }


            } 
            Console.WriteLine("Press any key to exit.");
            Console.ReadKey();
        }

        private static string GetUriWithToken()
        {
            using(var file = File.OpenText(@"C:\Users\Michas\Pictures\uri.text"))
            { 
            return file.ReadToEnd();
            }
        }

        private static void CreateToken()
        {
            var encSid = WebUtility.UrlEncode(SID);
            var encSecret = WebUtility.UrlEncode(secret);

            var body =
                String.Format("grant_type=client_credentials&client_id={0}&client_secret={1}&scope=notify.windows.com",
                    encSid, encSecret);

            var wb = new WebClient();
            wb.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
            var response = wb.UploadString(accesTokenuri , body);
            _token = GetOAuthJSON(response);
        }

        private static OAuthToken GetOAuthJSON(string json)
        {
            using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
            {
                var ser = new DataContractJsonSerializer(typeof(OAuthToken));
                var oAuthToken = (OAuthToken)ser.ReadObject(ms);
                return oAuthToken;
            }
        }

        [DataContract]
        class OAuthToken
        {
            [DataMember(Name = "access_token")]
            public string AccessToken { get; set; }
            [DataMember(Name = "token_type")]
            public string TokenType { get; set; }
        }
    }

来自windows store app的代码：

    private async void WNSExample()
            {
                try
                {
                    var wnsManager = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();

                    wnsManager.PushNotificationReceived += wnsManager_PushNotificationReceived;
                    SaveUriToFile(wnsManager.Uri);
                (Exception ex)
                {

                }
            }
private async void SaveUriToFile(string uri)
        {
            var storageFile = await Windows.Storage.KnownFolders.PicturesLibrary.CreateFileAsync("uri.text", CreationCollisionOption.ReplaceExisting);
            using (var stream = await storageFile.OpenStreamForWriteAsync())
            {
                using (var textWriter = new StreamWriter(stream))
                {
                    textWriter.Write(uri);
                    textWriter.Flush();
                }
            }
}

问题是模板的语法：launch =“”

应该是

发射= “” “”

或者省略lauch参数。

Windows应用商店应用不会收到来自WNS的推送通知
