Structuring GCM messages in PushSharp 4.0

问题

I'm somewhat confused in how I'm supposed to structure the message body for a GCM push notification using PushSharp. The docs as well as the test files in the GitHub repo show what looks to be the message structure as this:

            broker.QueueNotification (new GcmNotification {
                RegistrationIds = new List<string> { 
                    regId
                },
                Data = JObject.Parse ("{ \"somekey\" : \"somevalue\" }")
            });

I've been using Postman for testing in which I send a message in the following JSON format to https://gcm-http.googleapis.com/gcm/send.

{
    "to": "000-0000-mytoken-foo",
    "notification" : {
        "title" : "Push Test Notification",
        "body" : "GCM Test Push",
        "icon" : "icon",
        "color" : "#FF4081"
    }

}

Is the 'to' and the 'notification' sections of the message already taken care of by the framework? Based off the examples I've seen it seems as though I only need to enter the key:value pairs of the notification object but I can't seem to find where that is stated or an example of an actual message in the docs. I'm using the newest version (4.x) of PushSharp.

Hi there you can go like this

var config = new GcmConfiguration("senderKey", "apiKey", null);
config.GcmUrl = "https://fcm.googleapis.com/fcm/send"; //!!!!!gmc changed to fcm;)

var gcmBroker = new GcmServiceBroker(config);
gcmBroker.Start();

_gcmBroker.QueueNotification(new GcmNotification
                {
                    RegistrationIds = new List<string> { "YourDeviceToken" },
                    Notification = JObject.Parse(
                        "{" +
                            "\"title\" : \"" + yourMessageTitle + "\"," +
                            "\"body\" : \"" + yourMessageBody + "\"," +
                            "\"sound\" : \"mySound.caf\"" +
                        "}") ,
                    Data = JObject.Parse(
                        "{" +                            
                            "\"CustomDataKey1\" : \"" + yourCustomDataValue1 + "\"," +
                            "\"CustomDataKey2\" : \"" + yourCustomDataValue2 + "\"" +
                        "}")
                });

I did not test if the custom data values are arriving but the notification does:) The items starts with "your" are your dynamic arguments like parameters that you pass to that method etc. The question asked long time ago but i started to use pushsharp just now :) Hope this helps to PushSharp users.
