GCM java server example
提问by ViT-Vetal-
Does anyone have a link to GCM java 3rd Party Server example? I can't understand how to implement it. In http://developer.android.com/google/gcm/server.html, I could not find a complete example.
有没有人有 GCM java 3rd Party Server 示例的链接？我无法理解如何实现它。在http://developer.android.com/google/gcm/server.html 中，我找不到完整的示例。

The easiest way is to use gcm-server.jar(which you can get from here).
最简单的方法是使用gcm-server.jar（您可以从这里获得）。
Then the code you'll need to send a GCM message will look like this :
然后您需要发送 GCM 消息的代码将如下所示：
Sender sender = new Sender(apiKey);
Message message = new Message.Builder()
.addData("message", "this is the message")
.addData("other-parameter", "some value")
.build();
Result result = sender.send(message, registrationId, numOfRetries);

I would like to share a more better approach which confirms message delivered successfully or not. We can do this using RestTemplateand HTTPPost.
我想分享一个更好的方法来确认消息是否成功传递。我们可以使用RestTemplateand来做到这一点HTTPPost。
I will show how we can do it using gcm.jar
我将展示我们如何使用 gcm.jar
public class GCMJarGCM {
public static final String GCM_API_KEY = "Get this API key from Google Developer Console";
public static final String MESSAGE_VALUE = "Hello, Sending Notifications using GCM";
public static final String MESSAGE_KEY = "message";
public static final String REG_ID = "This you'll get once you register on GCM";
public static void main(String[] args) throws IOException {
Sender sender = new Sender(GCM_API_KEY);
ArrayList<String> devicesList = new ArrayList<String>();
devicesList.add(REG_ID);
Message message = new Message.Builder().timeToLive(30)
.delayWhileIdle(true).addData(MESSAGE_KEY, MESSAGE_VALUE).build();
MulticastResult result = sender.send(message, devicesList, 1);
sender.send(message, devicesList, 1);
System.out.println(result.toString());
}
}
The output you'll see like below:
您将看到如下输出：
MulticastResult(multicast_id=4951949299732552396,total=1,success=1,failure=0,canonical_ids=0,results: [[ messageId=0:1445408305351488%2a748ce7f9fd7ecd ]]
If you want to use HTTPPost or RestTemplate then you need to use EndPoint: https://android.googleapis.com/gcm/send
如果你想使用 HTTPPost 或 RestTemplate 那么你需要使用 EndPoint：https://android.googleapis.com/gcm/send
