如何在Android中为GCM项目创建服务器

Question

我正在创建一个关于Google Cloud Messaging(GCM)的项目,并且正在学习本教程.

我完成了客户端工作并在客户端设置了设备.我还使用以下代码注册了设备.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    GCMRegistrar.checkDevice(this);
    GCMRegistrar.checkManifest(this);
    final String regId = GCMRegistrar.getRegistrationId(this);
    if (regId.equals("")) {
        GCMRegistrar.register(this, "483910217912");
        Log.d(tag, "Registered");
    }
    else {
        Log.v(tag, "Already registered");
    }
}

现在我陷入了为GCM项目创建服务器的问题.请注意,我正在创建一个项目,以便在收到新消息时通知.但是,我没有实现接收消息的服务,但是我将在服务器设置完成后实现它.

Answer 1

您可以使用博客文章Google Cloud Messaging(GCM)教程在Android中创建GCM服务器,但我更愿意将PHP用于服务器端代码.您可以通过简单的步骤在cURL(PHP)中创建GCM服务器:

1. 从Google API控制台页面创建服务器密钥.

2. 标识要将此消息发送到的设备的设备令牌.

您可以在如何实现Android的GCM PHP推送服务器中找到简单的步骤来实现推送服务器.

你可以使用这段代码

package yourpackage.android.gcm.server;

import com.google.android.gcm.server.Message;
import com.google.android.gcm.server.MulticastResult;
import com.google.android.gcm.server.Sender;

import java.util.ArrayList;

class Notify {
    public static void main(String args[]) {

        try {

            Sender sender = new Sender("AIzaSyCn3N2OIm-EDtiGwTyQfSIB8NRvDtIOx30");

            ArrayList<String> devicesList = new ArrayList<String>();
//add you deviceID
            devicesList.add("APA91bELVJbxB_NLnLbTkkkX87SDdkJc6OfCN2slhC9t4cLq-KA32eGgiW4-Gi--ZEsEMKIh0AtYJMs5rQGswfm3cH1qK853WcpV98bkaplAaC5AiycDmifuVFSRl21vgf-Rqj0dCrFF");
                        //devicesList.add("APA91bHIdM4XGqrjJLTuwCX5OOrTYG4ACXYEVkZDM1bPs5qFdzJP4Bpql-sZqyKB8BU7fDtdxB84aTygHLyASYg_XNY6lqrcA4wj4sZHJXGVFzz_0UEADMfFCx9NAfRZxunIYso_dkBa");
            //APA91bFA-i2l3iEMnIBs0JK80pTLHOsE7p1s-DysRpKGas1MQOVILyIs9xwY7soysSWGz5Uif68uXR6F5Xn0tCTYesv78uQZxhC310a1cvf8aFohhfMGY6awbOSg3t1GRz2i3U-8kVSF
            // Use this line to send message without payload data
            // Message message = new Message.Builder().build();

            // use this line to send message with payload data
            Message message = new Message.Builder()
                    //.collapseKey("message")
                    //.timeToLive(241000)
                    .delayWhileIdle(true)
                    .addData("message", "Your message send")
                    .build();


                   /**/
            // Use this code to send to a single device
            // Result result = sender
            // .send(message,
            // "APA91bGiRaramjyohc2lKjAgFGpzBwtEmI8tJC30O89C2b3IjP1CuMeU1h9LMjKhmWuZwcXZjy1eqC4cE0tWBNt61Kx_SuMF6awzIt8WNq_4AfwflaVPHQ0wYHG_UX3snjp_U-5kJkmysdRlN6T8xChB1n3DtIq98w",
            // 1);

            // Use this for multicast messages
            MulticastResult result = sender.send(message, devicesList, 1);
            //sender.send(message, devicesList, 0);

            System.out.println(result.toString());
            if (result.getResults() != null) {
                int canonicalRegId = result.getCanonicalIds();
                if (canonicalRegId != 0) {
                }
            } else {
                int error = result.getFailure();
                System.out.println(error);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

该com.google.android.gcm.server库已弃用.只需将您的消息编码为JSON对象并将其发布到GCM URL https://android.googleapis.com/gcm/send

JSON示例:

 {
   "registration_ids" : ["APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx...",...],
   "data" : {
     "Team" : "Portugal",
     "Score" : "3",
     "Player" : "Varela",
   },
 }
