我需要为 gcm 的服务器端实现一个独立的应用程序，以将通知推送到设备。除了“入门”页面上的参考之外，我还能获得任何参考。人们对 xmpp 说了些什么。我们需要使用这个还是我们可以直接使用gcm服务器端方法。帮助。或者有没有其他简单的方法来实现这个。我希望我能正确地提出我的问题。

这是Java的GCM服务器端实现的好教程。网址：java gcm 服务器端实现

示例代码：java gcm 服务器端实现`{

    new Thread(){

        public void run(){

            try {
                //Please add here your project API key: "Key for browser apps (with referers)".
                //If you added "API key Key for server apps (with IP locking)" or "Key for Android apps (with certificates)" here
                //then you may get error responses.
                Sender sender = new  Sender("AIzaSyB7Ej255tpTaemk_-Ljmn4GcklldT14Hp4");

                // use this to send message with payload data
                Message message = new Message.Builder()
                .collapseKey("message")
                .timeToLive(3)
                .delayWhileIdle(true)
                .addData("message", "Welcome to Push Notifications") //you can get this message on client side app
                .build(); 

                //Use this code to send notification message to a single device
                Result result = sender.send(message,
                        "APA91bEbKqwTbvvRuc24vAYljcrhslOw-jXBqozgH8C2OB3H8R7U00NbIf1xp151ptweX9VkZXyHMik022cNrEETm7eM0Z2JnFksWEw1niJ2sQfU3BjQGiGMq8KsaQ7E0jpz8YKJNbzkTYotLfmertE3K7RsJ1_hAA",
                        1);
                System.out.println("Message Result: "+result.toString()); //Print message result on console

                //Use this code to send notification message to multiple devices
                ArrayList<String> devicesList = new ArrayList<String>();
                //add your devices RegisterationID, one for each device               
                devicesList.add("APA91bEbKqwTbvvRuc24vAYljcrhslOw-jXBqozgH8C2OB3H8R7U00NbIf1xp151ptweX9VkZXyHMik022cNrEETm7eM0Z2JnFksWEw1niJ2sQfU3BjQGiGMq8KsaQ7E0jpz8YKJNbzkTYotLfmertE3K7RsJ1_hAA");   
                devicesList.add("APA91bEVcqKmPnESzgnGpEstHHymcpOwv52THv6u6u2Rl-PaMI4mU3Wkb9bZtuHp4NLs4snBl7aXXVkNn-IPEInGO2jEBnBI_oKEdrEoTo9BpY0i6a0QHeq8LDZd_XRzGRSv_R0rjzzZ1b6jXY60QqAI4P3PL79hMg");   

                //Use this code for multicast messages   
                MulticastResult multicastResult = sender.send(message, devicesList, 0);
                System.out.println("Message Result: "+multicastResult.toString());//Print multicast message result on console

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }.start();   
}`

为 Java 实现 GCM 服务器端的最简单方法是使用 restful POST。网址：“ https://android.googleapis.com/gcm/send ”

示例代码：使用 scribe 框架作为使用者

public void pushToAndroidDevice(String deviceToken, String data) {  
    OAuthRequest request = new OAuthRequest(Verb.POST, "https://android.googleapis.com/gcm/send");
    request.addHeader("Authorization", "key=" + apiKey);
    request.addHeader("Content-Type", "application/json");

    request.addPayload(data);

    Response response = request.send();
}

有 2 种方法可以为 GCM 连接实现服务器
1) XMPP
2) HTTP

不同之处在于 XMPP 允许您从设备向服务器（双向）获取响应，而对于 GCM，HTTP 是（单向），您只能向设备发送推送通知。

如果您需要 Java 客户端和 HTTP 服务器的完整实现，这里是 GCM 客户端和服务器的链接
