许多教程都过时了，甚至当前的代码都没有考虑设备注册id何时更新或设备取消注册。如果不检查这些项目，最终将导致无法接收消息的问题。http://forum.loungekatt.com/viewtopic.php?t=63#p181

你也可以试试下面这段代码:

<?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);

这是我从CodeMonkeysRU分叉出来的一个库。

我分叉的原因是因为谷歌需要指数回退。我使用redis服务器将消息排队，并在设定的时间后重新发送。

我还将其更新为支持iOS。

实际上，我现在在Zend_Mobile树的一个分支中工作:https://github.com/mwillbanks/Zend_Mobile/tree/feature/gcm

这将与ZF 1.12一起发布，但是，它应该会给你一些关于如何做到这一点的很好的例子。

这里有一个关于它如何工作的快速演示....

<?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']);
    }
}

这很容易做到。Elad Nava放在这里的页面上的cURL代码是有效的。Elad评论了他收到的错误。

描述在为该收件人处理消息时发生的错误的字符串。可能的值与上表中记录的值相同，再加上“Unavailable”(意味着GCM服务器繁忙，无法为特定的收件人处理消息，因此可以重试)。

我已经得到了一个服务设置，似乎已经工作(ish)，到目前为止，我已经回来的都是不可用的回报从谷歌。这种情况很可能很快就会改变。

要回答这个问题，请使用PHP，确保Zend框架在您的include路径中，并使用以下代码:

<?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);

结果出来了。一个在Zend Framework PHP中使用google新GCM的工作示例(很快就会工作)。

<?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);
?>
