问题描述

你好我在应用程序中使用Google云消息的每一个人。我在下面给出了我的app.link的android hive教程。


$ b http://www.androidhive.info/2012/10/android-push-notifications -using-google-cloud-messaging-gcm-php-and-mysql /

所有工作都适合我,但问题在于,从远程服务器发送,在客户端我收到消息警报,但没有消息只写了空消息。我收到空消息。如何修复它?



消息接收的Java代码



/ **
*方法呼吁接收新消息
* * /

  @Override 
protected void onMessage(Context context,意图意图){
Log.i(TAG,收到的消息);
String message = intent.getExtras()。getString(price);

displayMessage(context,message);
//通知用户
generateNotification(context,message);
}



服务器端代码





  //将代码放在这里
//构造函数
函数__construct(){



$ b / **
*发送推送通知
* /
public function send_notification($ registatoin_ids,$ message){
// include config
include_once($ _ SERVER [DOCUMENT_ROOT]。*****);

$ apiKey =*******;
//设置POST变量
$ url ='https://android.googleapis.com/gcm/send';

$ fields = array(
'registration_ids'=> $ registatoin_ids,
'data'=> $ message,
);

$ headers = array(
'Authorization:key ='。$ apiKey,
'Content-Type:application / json'
);

//打开连接
$ ch = curl_init();

//设置网址,POST变量的数量,POST数据
curl_setopt($ ch,CURLOPT_URL,$ url);

curl_setopt($ ch,CURLOPT_POST,true);
curl_setopt($ ch,CURLOPT_HTTPHEADER,$ headers);
curl_setopt($ ch,CURLOPT_RETURNTRANSFER,true);

//临时禁用SSL证书支持
curl_setopt($ ch,CURLOPT_SSL_VERIFYPEER,false);

curl_setopt($ ch,CURLOPT_POSTFIELDS,json_encode($ fields));

//执行后
$结果= curl_exec($ ch);
// if($ result == FALSE){
// die('Curl failed:'。curl_error($ ch));
//}

//关闭连接
curl_close($ ch);
echo $ result;
}

}

数组消息



  $ message = array(message=&$; $ message); 

在此先感谢。

解决方案

它是一个猜测,确保从服务器发送的与您在客户端使用的相同。在本教程中,它的价格。所以确保两者都是相同的。



服务器端: $ message = array(price=> $消息);

Android:

(标记,接收到的消息);
Log.i(TAG,Received message);
String message = intent.getExtras()。getString(price);

displayMessage(context,message);
//通知用户
generateNotification(context,message);
}


Hello every one I am using Google cloud messaging in my app. I am following android hive tutorial for my app.link of the tutorial is given below.

http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/

All is working fine for me but the problem is that when a message is sent from remote server, on client side i receive alert of message but having no message just written null message. I am receiving null message. how can i fix it?

Java Code on Message Receive

/** * Method called on Receiving a new message * */

  @Override
  protected void onMessage(Context context, Intent intent) {
    Log.i(TAG, "Received message");
    String message = intent.getExtras().getString("price");

    displayMessage(context, message);
    // notifies user
    generateNotification(context, message);
}

Server side code

//put your code here
// constructor
function __construct() {

}


/**
 * Sending Push Notification
 */
public function send_notification($registatoin_ids, $message) {
    // include config
    include_once($_SERVER["DOCUMENT_ROOT"] ."*****");

    $apiKey = "*******";
    // Set POST variables
    $url = 'https://android.googleapis.com/gcm/send';

    $fields = array(
        'registration_ids' => $registatoin_ids,
        'data' => $message,
    );

    $headers = array(
            'Authorization: key=' . $apiKey,
            'Content-Type: application/json'
    );

    // Open connection
    $ch = curl_init();

    // Set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Disabling SSL Certificate support temporarly
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

    // Execute post
    $result = curl_exec($ch);
   // if ($result == FALSE) {
   //     die('Curl failed: ' . curl_error($ch));
   // }

    // Close connection
    curl_close($ch);
    echo $result;
}

}

array of mesage

   $message = array("message" => $message);

Thanks in Advance.

解决方案

Its a guess, Make sure the key which send from the server is same as you used in the client side. In this tutorial its price . So make sure both are same.

Server side: $message = array("price" => $message);

Android:

@Override
    protected void onMessage(Context context, Intent intent) {
        Log.i(TAG, "Received message");
        String message = intent.getExtras().getString("price");

        displayMessage(context, message);
        // notifies user
        generateNotification(context, message);
    }
