Question

我尝试使用经过身份验证的服务器向我的Windows Phone 8应用发送通知，但每当尝试发送通知时，我都会收到401错误。

我一直在按照MSDN网页上的说明进行操作，即http://msdn.microsoft.com/library/windows/apps/ff941099(v=vs.105).aspx，其中The Key-Usage value of the TLS certificate must be set to include client authentication.我不知道这意味着什么，但在线搜索并不是给我任何线索。

可能是，这是不正确的，或者它可能是我的代码所以如下所示。

VB.NET代码：

Private Async Sub ApplicationBarPin_Click(sender As Object, e As EventArgs)
    ' Holds the push channel that is created or found.
            Dim pushChannel As HttpNotificationChannel

            ' The name of our push channel.
            Dim channelName As String = "WindowsPhoneTrainTileNotification"

            ' Try to find the push channel.
            pushChannel = HttpNotificationChannel.Find(channelName)

            ' If the channel was not found, then create a new connection to the push service.
            If pushChannel Is Nothing Then
                pushChannel = New HttpNotificationChannel(channelName, "redsquirrelsoftware.co.uk")
                uri_timer = New DispatcherTimer
                uri_timer.Interval = TimeSpan.FromSeconds(5)
                AddHandler uri_timer.Tick, AddressOf UriTimerTick
                uri_timer.Start()

                ' Register for all the events before attempting to open the channel.
                AddHandler pushChannel.ChannelUriUpdated, AddressOf PushChannel_TileChannelUriUpdated
                AddHandler pushChannel.ErrorOccurred, AddressOf PushChannel_TileErrorOccurred

                pushChannel.Open()

                pushChannel.BindToShellTile()
            Else
                ' The channel was already open, so just register for all the events.
                AddHandler pushChannel.ChannelUriUpdated, AddressOf PushChannel_TileChannelUriUpdated
                AddHandler pushChannel.ErrorOccurred, AddressOf PushChannel_TileErrorOccurred

                Dim form As New MultipartFormDataContent()
                form.Add(New StringContent(Statics.getUserID), "userId")
                form.Add(New StringContent(pushChannel.ChannelUri.ToString()), "uri")
                form.Add(New StringContent(Statics.CurrentScheduleId), "scheduleId")

                Dim httpClient As HttpClient = New HttpClient()

                Dim response As HttpResponseMessage = Await httpClient.PostAsync("http://redsquirrelsoftware.co.uk/trains/push/WPTileSubscribe.php", form)
            End If

            ShellTile.Create(New Uri("/Route.xaml?scheduleId=" & scheduleId, UriKind.Relative), secondaryTile, True) 'Create SecondaryTile and pass querystring to navigation url.
        Catch ex As Exception
        End Try

    End If
End Sub

Private Async Sub PushChannel_TileChannelUriUpdated(sender As Object, e As NotificationChannelUriEventArgs)
    Dim form As New MultipartFormDataContent()
    form.Add(New StringContent(Statics.getUserID), "userId")
    form.Add(New StringContent(e.ChannelUri.ToString()), "uri")
    form.Add(New StringContent(Statics.CurrentScheduleId), "scheduleId")

    Dim httpClient As HttpClient = New HttpClient()

    Dim response As HttpResponseMessage = Await httpClient.PostAsync("http://redsquirrelsoftware.co.uk/trains/push/WPTileSubscribe.php", form)
End Sub

Private Sub PushChannel_TileErrorOccurred(sender As Object, e As NotificationChannelErrorEventArgs)
    MessageBox.Show("Error creating live tile, please try again")
End Sub

Private Async Sub UriTimerTick(sender As Object, e As EventArgs)
    Try
        If pushChannel.ChannelUri IsNot Nothing Then
            Dim form As New MultipartFormDataContent()
            form.Add(New StringContent(Statics.getUserID), "userId")
            form.Add(New StringContent(pushChannel.ChannelUri.ToString()), "uri")
            form.Add(New StringContent(Statics.CurrentScheduleId), "scheduleId")

            Dim httpClient As HttpClient = New HttpClient()

            Dim response As HttpResponseMessage = Await httpClient.PostAsync("http://redsquirrelsoftware.co.uk/trains/push/WPTileSubscribe.php", form)
            uri_timer.Stop()
        End If
    Catch ex As Exception
    End Try

End Sub

按预期工作，URI存储在我的数据库中（从HTTPS开始，并且在URI中也不包含throttledthirdparty，表明此代码有效）。

train_movements.php：

<?php

$WPN = new WPN($packageSID, $clientSecret);
$xml_data = $WPN->build_tile_xml($sched_id, strtoupper($loc), "$eventTypeStr $dt (". strtolower($variation_status) . ")");
$WPNResponse = $WPN->post_tile($uri, $xml_data);
if($WPNResponse->error == true) {
    $my_file = $logFile;
    $handle = fopen($my_file, 'a') or die('Cannot open file:  '.$my_file);

        else{
            return new WPNResponse('Unknown error while sending message', $code, true);
        }
    }
}
?>

我的代码可能存在错误，或者可能是因为我没有正确设置后端内容（大多数MSDN文档都针对的是Windows服务器和.aspx，所以我很高兴试图复制这些说明，但可能在某个地方出错！）。

如果有人可以帮助修复代码中的错误，或者使用SSL证书的客户端身份验证，那将非常感激！

谢谢，杰克

看一看 Windows Notifications Service: 401 Invalid Token when trying to create a Toast notification in PHP 无效-令牌时-试图对创建-A-吐司-N

请确保您在申请访问令牌时将应用的包SID 作为'client_id'参数发送，而不是应用的client_id。

这实在令人困惑，两者都可以从Microsoft的服务器获取access_token，但只有包裹SID请求的令牌在发送Toast通知时不会给你401错误。
