c# - PushSharp APNS通知错误不支持所请求的功能

我正在使用PushSharp 4.0.10
在Apns代理的OnNotificationFailed事件中，出现“不支持所请求的功能”异常。有我的经纪人创作者

private static ApnsServiceBroker CreateApnsBroker(string certificate)
{
    // Configuration (NOTE: .pfx can also be used here)
    var config = newApnsConfiguration(
        ApnsConfiguration.ApnsServerEnvironment.Sandbox,
        certificate,
        ConfigurationManager.AppSettings["Cert_Passwd"],
        false);

    // Create a new broker
    var apnsBroker = new ApnsServiceBroker(config);

    // Wire up events
    apnsBroker.OnNotificationFailed += (notification, aggregateEx) =>
    {
        aggregateEx.Handle(ex =>
        {
            // See what kind of exception it was to further diagnose
            if (ex is ApnsNotificationException notificationException)
            {
                // Deal with the failed notification
                var apnsNotification = notificationException.Notification;
                var statusCode = notificationException.ErrorStatusCode;

                Logger.Info($"Apple Notification Failed:
                    ID={apnsNotification.Identifier},
                    Code={statusCode}",
                    ex);
            }
            else
            {
                // Inner exception might hold more useful information
                // like an ApnsConnectionException
                Logger.Info($"Apple Notification Failed for some unknown reason:
                    {ex.InnerException}",
                    ex);
            }
                // Mark it as handled
                return true;
            });
    };

    apnsBroker.OnNotificationSucceeded += (notification) =>
    {
        Logger.Info($"Apple Notification Sent for device {notification.DeviceToken}");
    };

    return apnsBroker;
}

发送通知

private static void QueueNotification(
    ApnsServiceBroker apnsBroker,
    string deviceToken,
    string payload)
{
    // Queue a notification to send
    apnsBroker.QueueNotification(new ApnsNotification
    {
        DeviceToken = deviceToken,
        Payload = JObject.Parse(payload),
        Expiration = DateTime.Now.AddDays(2)
    });
}

当我在OnNotificationFailed中停止代理时，捕获异常。在PushSharp和我的代码中，我使用ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
使用.p12证书进行voip通知，该证书已添加到mmc中
我怎么了

最佳答案

我克隆了PushSharp存储库，编译了本地dll，更改了项目链接，这是可行的，但是我不知道为什么。
