php - Android GCM 数据包发送

Question

我可以使用Android GCM通过一个请求发送多个推送通知吗？

Answer 1

是的你可以。我使用以下代码以 1000 个用户为一组发送它们：

$url = 'https://android.googleapis.com/gcm/send';
$fields['data'] = $message;

$headers = array(
        'Authorization: key=' . $api_key,
        'Content-Type: application/json'
);
//echo "Reg ids: ".var_dump($fields['registration_ids'])."<br>";
    for ($i = 0; $i < 9998; $i++) {
        $registration_ids[$i+2] = $i;
    }
echo "Total necessary requests to GCM: ".(intval(count($registration_ids)/1000)+1)."<br>";
for ($j = 0; $j < count($registration_ids)/1000; $j++) {
    echo "Processing request number ".($j + 1)."...<br>";
    $fields['registration_ids'] = array();
    for($i=0;$i < 1000 && ($i+1000*$j) < count($registration_ids);$i++){
        $fields['registration_ids'][$i] = $registration_ids[$i+1000*$j];
    }
    echo "Sending push to devices: ".(1000*$j)." - ".(count($fields['registration_ids'])+1000*$j)."<br>";

    // 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($ch, CURLOPT_SSL_VERIFYPEER, false);
 //var_dump($fields);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

    // Execute post

    $result = curl_exec($ch);
    //$result = true;
    if ($result === FALSE) {
       die('Curl failed: ' . curl_error($ch));
    }
    else
        echo "Curl success<br>";

    echo $result."<br>";

我希望你觉得这段代码有用

我们可以向多达 1000 台设备发送相同的消息。 https://developers.google.com/cloud-messaging/http-server-ref#table1

但是我们不能通过一个请求向不同的设备发送不同的通知。
