带有Firebase的Pushsharp 4.0

Question

在阅读了很多帖子后，我找不到一个完整的例子，如何在Firebase中使用Pushsharp 4.0发送GCM推送通知。很多使用PushSharp的例子都是使用旧的谷歌云消息，而不是Firebase和/或旧的PushSharp版本。

有没有人有一个使用PushSharp 4.0和Firebase发送GCM推送通知的稳定和有效的代码示例？

你可以试试这个：https://github.com/Redth/PushSharp/issues/711

我自己还没有尝试过，但从上面帖子的评论来看，似乎人们已经成功地使用了PushSharp和Firebase，并提出了修改建议。

我能够让PushSharp相对容易地与FCM一起工作。我以为这会难得多。以下是我采取的步骤：

我在console.firebase.google.com

• Then上创建了一个新项目，我转到了settings =>

1. Messaging。我使用该SenderID作为我的PushSharp发件人ID，旧版服务器密钥作为我的PushSharp身份验证密钥。
2. 接下来，我转到google play控制台，选择项目，然后选择开发工具=>服务和应用程序接口。
3. 然后我通过在“链接的发件人ID”字段中输入SenderID将应用程序项目链接到新的=>项目。

这应该是服务器正常工作所要做的全部工作。

现在，我需要将应用程序连接到这个新的SenderID。我认为这通常是通过输入google-services.json文件来完成的，如Firebase设置中所示。但是，我使用PhoneGap/Cordova插件来发送通知。所以，我这样做：

1. 将GCM_SENDER_ID更改为上面的SenderID。

不幸的是，我不得不重新发布新版本的应用程序才能让它正常工作。但它确实起作用了。

希望这对其他人有帮助。

这个控制台程序对我来说运行得很好。

    static void Main(string[] args)
    {
        try
        {
            string token = "putYourSecretTokenHere";
            using (var s = new FcmPushNotificationService())
            {
                s.SendPushNotification(token);
                Console.ReadLine();
            }

        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            Console.ReadLine();
