Question

我已成功将数据从php服务器页面发送到带有JAXL的Android客户端..

我仔细阅读了Google Cloud Message Offical网站的指南..对于Upstream，只有这些文件：

public void onClick(final View view) {
    if (view == findViewById(R.id.send)) {
        new AsyncTask() {
            @Override
            protected String doInBackground(Void... params) {
                String msg = "";
                try {
                    Bundle data = new Bundle();
                    data.putString("my_message", "Hello World");
                    data.putString("my_action","SAY_HELLO");
                    String id = Integer.toString(msgId.incrementAndGet());
                    gcm.send(SENDER_ID + "@gcm.googleapis.com", id, data);
                    msg = "Sent message";
                } catch (IOException ex) {
                    msg = "Error :" + ex.getMessage();
                }
                return msg;
            }

            @Override
            protected void onPostExecute(String msg) {
                mDisplay.append(msg + "\n");
            }
        }.execute(null, null, null);
    } else if (view == findViewById(R.id.clear)) {
        mDisplay.setText("");
    }
}

说出来：

在应用服务器上接收XMPP消息
When GCM receives an upstream messaging call from a client app, it generates the necessary XMPP stanza for sending the upstream message.
GCM添加类别和字段，然后发送类似的节以下内容到app服务器：

<message id="">
  <gcm xmlns="google:mobile:data">
  {
      "category":"com.example.yourapp", // to know which app sent it
      "data":
      {
          "hello":"world",
      },
      "message_id":"m-123",
      "from":"REGID"
  }
  </gcm>
</message>

但现在我有一些问题，因为上游的文件有限。

1-）Android发送JSON数据，发送者ID为上游...但是当我注册到api时，没有被问及app server。发件人ID通过包识别我的Gmail帐户的应用程序。不是app服务器。那么gcm发送客户来的数据呢？如何让GCM了解我的应用服务器..

2-）我预算有限，我的服务器是共享帐户Web服务器。所以我必须使用php ...但我已阅读文档，“您的应用服务器应该是持久连接”而不是连接＆amp;定期断开...我可以使用app服务器作为PHP吗？ GCM连接Php scrpit，它可以排出数据并回复到Android客户端吗？

Answer 1

您可能知道，服务器和GCM之间的连接需要sender-id和API密钥。此外，当客户端应用程序想要发送上游消息时，它使用相同的sender-id。所以GCM知道它应该向谁发送上游数据。
您的编程语言没有限制，当然您可以使用PHP。您只需要维护与GCM服务器的持久连接。

不要关心某些断开连接，请注意，如果您的服务器已关闭，Google将重试发送上游消息，并且没有向特定消息的GCM发送ACK。

以下是我如何管理上游消息...

首先获得JAXL

把它放在你的apache执行目录...

创建新的php脚本文件......

<?php
include_once 'jaxl.php';

$client = new JAXL(array(
    'jid' => '/*Write sender ID here*/@gcm.googleapis.com',
    'pass' => 'Write here your GCM apı key',
    'host' => 'gcm-preprod.googleapis.com',
    'port' => 5236,
   'strict' => false,
    'force_tls' => true,
    'log_level' => JAXL_DEBUG,
    'auth_type' => 'PLAIN',
    'protocol' => 'tls',
     'ssl' => TRUE,
    'log_path'=> 'ex.txt'  /*This create text file to comminication between gcm and your server*/
));

$client->add_cb('on_message_stanza', function($msg) {
 echo 'now what!!';
 });

 $client->add_cb('on_auth_success', function() {
 echo 'it should';
//Here is for sending downstream msg
  }); 

 $client->add_cb('on_error_message',function()
 {
 global $client;
 echo 'error<br/>';
 _info('got on_error_message cb jid'.$client->full_jid->to_string());
 });

$client->start();

?>

在android部分，在你与GCM集成之后，一个带有内部点击监听器的按钮

String msg = "";
                        try {
                            Bundle data = new Bundle();
                            data.putString("my_message", "Hello World");
                            data.putString("my_action", "SAY_HELLO");
                            String id = Integer.toString(incrementAndGet());
                            gcm.send( "/*Write here sender ID*/"+ "@gcm.googleapis.com", id, data);
                            msg = "Sent message";
                        } catch (IOException ex) {
                            msg = "Error :" + ex.getMessage();
                        }
                        Log.d(msg,"-------------");

然后，执行你上面写的php脚本，然后单击按钮以发送上游消息，看看jaxl创建的ex.txt，你会看到app发送的“Hello World”消息

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Log.d(TAG, "FCM Token creation logic");

    // Get variables reference
    deviceText = (TextView) findViewById(R.id.deviceText);
    editTextEcho = (EditText) findViewById(R.id.editTextEcho);
    buttonUpstreamEcho = (Button) findViewById(R.id.buttonUpstreamEcho);

    //Get token from Firebase
    FirebaseMessaging.getInstance().subscribeToTopic("test");
    final String token = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Token: " + token);
    deviceText.setText(token);

    //Call the token service to save the token in the database
    tokenService = new TokenService(this, this);
    tokenService.registerTokenInDB(token);

    buttonUpstreamEcho.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Log.d(TAG, "Echo Upstream message logic");
            String message = editTextEcho.getText().toString();
            Log.d(TAG, "Message: " + message + ", recipient: " + token);
            FirebaseMessaging.getInstance().send(new RemoteMessage.Builder(FCM_PROJECT_SENDER_ID + FCM_SERVER_CONNECTION)
                    .setMessageId(Integer.toString(RANDOM.nextInt()))
                    .addData("message", message)
                    .addData("action", BACKEND_ACTION_ECHO)
                    .build());
            // To send a message to other device through the XMPP Server, you should add the
            // receiverId and change the action name to BACKEND_ACTION_MESSAGE in the data
        }
    });

}
