带 PHP 的 GCM（谷歌云消息）

Question

Update: GCM is deprecated, use FCM

How can I integrate the new Google Cloud Messaging in a PHP backend?

Answer 1

This code will send a GCM message to multiple registration IDs via PHP CURL.

// Payload data you want to send to Android device(s)
// (it will be accessible via intent extras)    
$data = array('message' => 'Hello World!');

// The recipient registration tokens for this notification
// https://developer.android.com/google/gcm/    
$ids = array('abc', 'def');

// Send push notification via Google Cloud Messaging
sendPushNotification($data, $ids);

function sendPushNotification($data, $ids) {
    // Insert real GCM API key from the Google APIs Console
    // https://code.google.com/apis/console/        
    $apiKey = 'abc';

    // Set POST request body
    $post = array(
                    'registration_ids'  => $ids,
                    'data'              => $data,
                 );

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

    // Initialize curl handle       
    $ch = curl_init();

    // Set URL to GCM push endpoint     
    curl_setopt($ch, CURLOPT_URL, 'https://gcm-http.googleapis.com/gcm/send');

    // Set request method to POST       
    curl_setopt($ch, CURLOPT_POST, true);

    // Set custom request headers       
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    // Get the response back as string instead of printing it       
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Set JSON post data
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post));

    // Actually send the request    
    $result = curl_exec($ch);

    // Handle errors
    if (curl_errno($ch)) {
        echo 'GCM error: ' . curl_error($ch);
    }

    // Close curl handle
    curl_close($ch);

    // Debug GCM response       
    echo $result;
}

<?php
    // Replace with the real server API key from Google APIs
    $apiKey = "your api key";

    // Replace with the real client registration IDs
    $registrationIDs = array( "reg id1","reg id2");

    // Message to be sent
    $message = "hi Shailesh";

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

    $fields = array(
        'registration_ids' => $registrationIDs,
        'data' => array( "message" => $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);
    //curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields));

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    // curl_setopt($ch, CURLOPT_POST, true);
    // curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode( $fields));

    // Execute post
    $result = curl_exec($ch);

    // Close connection
    curl_close($ch);
    echo $result;
    //print_r($result);
    //var_dump($result);
?>

Answer 3

It's easy to do. The cURL code that's on the page that Elad Nava has put here works. Elad hascommented about the error he's receiving.

String describing an error that occurred while processing the message for that recipient. The possible values are the same as documented in the above table, plus "Unavailable" (meaning GCM servers were busy and could not process the message for that particular recipient, so it could be retried).

I've got a service set up already that seems to be working (ish), and so far all I've had back are unavailable returns from Google. More than likely this will change soon.

To answer the question, use PHP, make sure the Zend Framework is in your include path, and use this code:

<?php
    ini_set('display_errors',1);
    include"Zend/Loader/Autoloader.php";
    Zend_Loader_Autoloader::getInstance();

    $url = 'https://android.googleapis.com/gcm/send';
    $serverApiKey = "YOUR API KEY AS GENERATED IN API CONSOLE";
    $reg = "DEVICE REGISTRATION ID";

    $data = array(
            'registration_ids' => array($reg),
            'data' => array('yourname' => 'Joe Bloggs')
    );

    print(json_encode($data));

    $client = new Zend_Http_Client($url);
    $client->setMethod('POST');
    $client->setHeaders(array("Content-Type" => "application/json", "Authorization" => "key=" . $serverApiKey));
    $client->setRawData(json_encode($data));
    $request = $client->request('POST');
    $body = $request->getBody();
    $headers = $request->getHeaders();
    print("<xmp>");
    var_dump($body);
    var_dump($headers);

And there we have it. A working (it will work soon) example of using Googles new GCM in Zend Framework PHP.

Answer 4

After searching for a long time finally I am able to figure out what I exactly needed, Connecting to the GCM using PHP as a server side scripting language, The following tutorial will give us a clear idea of how to setup everything we need to get started with GCM

Android Push Notifications using Google Cloud Messaging (GCM), PHP and MySQL

Answer 5

I actually have this working now in a branch in my Zend_Mobile tree: https://github.com/mwillbanks/Zend_Mobile/tree/feature/gcm

This will be released with ZF 1.12, however, it should give you some great examples on how to do this.

Here is a quick demo on how it would work....

<?php
require_once 'Zend/Mobile/Push/Gcm.php';
require_once 'Zend/Mobile/Push/Message/Gcm.php';

$message = new Zend_Mobile_Push_Message_Gcm();
$message->setId(time());
$message->addToken('ABCDEF0123456789');
$message->setData(array(
    'foo' => 'bar',
    'bar' => 'foo',
));

$gcm = new Zend_Mobile_Push_Gcm();
$gcm->setApiKey('MYAPIKEY');

$response = false;

try {
    $response = $gcm->send($message);
} catch (Zend_Mobile_Push_Exception $e) {
    // all other exceptions only require action to be sent or implementation of exponential backoff.
    die($e->getMessage());
}

// handle all errors and registration_id's
foreach ($response->getResults() as $k => $v) {
    if ($v['registration_id']) {
        printf("%s has a new registration id of: %s\r\n", $k, $v['registration_id']);
    }
    if ($v['error']) {
        printf("%s had an error of: %s\r\n", $k, $v['error']);
    }
    if ($v['message_id']) {
        printf("%s was successfully sent the message, message id is: %s", $k, $v['message_id']);
    }
}

Answer 6

Also you can try this piece of code, source :

<?php
    define("GOOGLE_API_KEY", "AIzaSyCJiVkatisdQ44rEM353PFGbia29mBVscA");
    define("GOOGLE_GCM_URL", "https://android.googleapis.com/gcm/send");

    function send_gcm_notify($reg_id, $message) {
        $fields = array(
            'registration_ids'  => array( $reg_id ),
            'data'              => array( "message" => $message ),
        );

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

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, GOOGLE_GCM_URL);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

        $result = curl_exec($ch);
        if ($result === FALSE) {
            die('Problem occurred: ' . curl_error($ch));
        }

        curl_close($ch);
        echo $result;
    }

    $reg_id = "APA91bHuSGES.....nn5pWrrSz0dV63pg";
    $msg = "Google Cloud Messaging working well";

    send_gcm_notify($reg_id, $msg);

Answer 7

A lot of the tutorials are outdated, and even the current code doesn't account for when device registration_ids are updated or devices unregister. If those items go unchecked, it will eventually cause issues that prevent messages from being received. http://forum.loungekatt.com/viewtopic.php?t=63#p181

Answer 8

<?php

function sendMessageToPhone($deviceToken, $collapseKey, $messageText, $yourKey) {    
    echo "DeviceToken:".$deviceToken."Key:".$collapseKey."Message:".$messageText
            ."API Key:".$yourKey."Response"."<br/>";

    $headers = array('Authorization:key=' . $yourKey);    
    $data = array(    
        'registration_id' => $deviceToken,          
        'collapse_key' => $collapseKey,
        'data.message' => $messageText);  
    $ch = curl_init();    

    curl_setopt($ch, CURLOPT_URL, "https://android.googleapis.com/gcm/send");    
    if ($headers)    
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);    
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);    
    curl_setopt($ch, CURLOPT_POST, true);    
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);    

    $response = curl_exec($ch);    
    var_dump($response);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);    
    if (curl_errno($ch)) {
        return false;
    }    
    if ($httpCode != 200) {
        return false;
    }    
    curl_close($ch);    
    return $response;    
}  

$yourKey = "YOURKEY";
$deviceToken = "REGISTERED_ID";
$collapseKey = "COLLAPSE_KEY";
$messageText = "MESSAGE";
echo sendMessageToPhone($deviceToken, $collapseKey, $messageText, $yourKey);
?>

In above script just change:

"YOURKEY" to API key to Server Key of API console.
"REGISTERED_ID" with your device's registration ID
"COLLAPSE_KEY" with key which you required
"MESSAGE" with message which you want to send

Let me know if you are getting any problem in this I am able to get notification successfully using the same script.

Answer 9

You can use this PHP library available on packagist:

https://github.com/CoreProc/gcm-php

After installing it you can do this:

$gcmClient = new GcmClient('your-gcm-api-key-here');

$message = new Message($gcmClient);

$message->addRegistrationId('xxxxxxxxxx');
$message->setData([
    'title' => 'Sample Push Notification',
    'message' => 'This is a test push notification using Google Cloud Messaging'
]);

try {

    $response = $message->send();

    // The send() method returns a Response object
    print_r($response);

} catch (Exception $exception) {

    echo 'uh-oh: ' . $exception->getMessage();

}

Answer 10

Here's a library I forked from CodeMonkeysRU.

The reason I forked was because Google requires exponential backoff. I use a redis server to queue messages and resend after a set time.

I've also updated it to support iOS.

use this

 function pnstest(){

                $data = array('post_id'=>'12345','title'=>'A Blog post', 'message' =>'test msg');

                $url = 'https://fcm.googleapis.com/fcm/send';

                $server_key = 'AIzaSyDVpDdS7EyNgMUpoZV6sI2p-cG';

                $target ='fO3JGJw4CXI:APA91bFKvHv8wzZ05w2JQSor6D8lFvEGE_jHZGDAKzFmKWc73LABnumtRosWuJx--I4SoyF1XQ4w01P77MKft33grAPhA8g-wuBPZTgmgttaC9U4S3uCHjdDn5c3YHAnBF3H';

                $fields = array();
                $fields['data'] = $data;
                if(is_array($target)){
                    $fields['registration_ids'] = $target;
                }else{
                    $fields['to'] = $target;
                }

                //header with content_type api key
                $headers = array(
                    'Content-Type:application/json',
                  'Authorization:key='.$server_key
                );

                $ch = curl_init();
                curl_setopt($ch, CURLOPT_URL, $url);
                curl_setopt($ch, CURLOPT_POST, true);

                return $result;

}

I know this is a late Answer, but it may be useful for those who wants to develop similar apps with current FCM format (GCM has been deprecated).
The following PHP code has been used to send topic-wise podcast. All the apps registered with the mentioned channel/topis would receive this Push Notification.

<?php

try{
$fcm_token = 'your fcm token';
$service_url = 'https://fcm.googleapis.com/fcm/send';
$channel = '/topics/'.$adminChannel;
echo $channel.'</br>';
      $curl_post_body = array('to' => $channel,
        'content_available' => true,
        'notification' => array('click_action' => 'action_open',
                            'body'=> $contentTitle,
                            'title'=>'Title '.$contentCurrentCat. ' Updates' ,
                            'message'=>'44'),
        'data'=> array('click_action' => 'action_open',
                            'body'=>'test',
                            'title'=>'test',
                            'message'=>$catTitleId));

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

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $service_url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($curl_post_body));

    $result = curl_exec($ch);
    if ($result === FALSE) {
        die('FCM Send Error: ' . curl_error($ch));
        echo 'failure';
    }else{

    echo 'success' .$result;
    }
    curl_close($ch);
    return $result;

}
catch(Exception $e){

    echo 'Message: ' .$e->getMessage();
}
?>
