通过FCM C＃发送推到Android（火力地堡云通讯） [英] Send push to Android by C# using FCM (Firebase Cloud Messaging)

问题描述

我用这个代码用C＃与GCM发送通知消息，使用的WinForms，Web表单，等等。现在我要发送到FCM（火力地堡云通讯）。我应该更新我的代码？

I am using this code to send notification message by C# with GCM, using Winforms, Webforms, whatever. Now I want to send to FCM (Firebase Cloud Messaging). Should I update my code? :

public class AndroidGCMPushNotification
{
    public AndroidGCMPushNotification()
    {
        //
        // TODO: Add constructor logic here
        //
    }
    public string SendNotification(string deviceId, string message)
    {
        string SERVER_API_KEY = "server api key";        
        var SENDER_ID = "application number";
        var value = message;
        WebRequest tRequest;
        tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
        tRequest.Method = "post";
        tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
        tRequest.Headers.Add(string.Format("Authorization: key={0}", SERVER_API_KEY));

        tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));

        string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + value + "&data.time=" + System.DateTime.Now.ToString() + "&registration_id=" + deviceId + "";
        Console.WriteLine(postData);
        Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
        tRequest.ContentLength = byteArray.Length;

        Stream dataStream = tRequest.GetRequestStream();
        dataStream.Write(byteArray, 0, byteArray.Length);
        dataStream.Close();

        WebResponse tResponse = tRequest.GetResponse();

        dataStream = tResponse.GetResponseStream();

        StreamReader tReader = new StreamReader(dataStream);

        String sResponseFromServer = tReader.ReadToEnd();


        tReader.Close();
        dataStream.Close();
        tResponse.Close();
        return sResponseFromServer;
    }
}

但GCM改为FCM。这是相同的代码来发送通知？
我在哪里可以找到SERVER_API_KEY？是相同的解决方案？

but the GCM was changed to FCM. Is this same code to send the notification? Where can I find the SERVER_API_KEY? Is the same solution?

推荐答案

试图发送一个JSON对象。
替换这样的：

Try to send a json object. Replace this:

tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";    
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + value + "&data.time=" + System.DateTime.Now.ToString() + "&registration_id=" + deviceId + "";
        Console.WriteLine(postData);
        Byte[] byteArray = Encoding.UTF8.GetBytes(postData);

有关这一点：

tRequest.ContentType = "application/json"; 
    var data = new
        {
            to = deviceId,
            notification = new
            {
                body = "This is the message",
                title = "This is the title",
                icon = "myicon"
            }
        };

        var serializer = new JavaScriptSerializer();
        var json = serializer.Serialize(data);

        Byte[] byteArray = Encoding.UTF8.GetBytes(json);
