我已经实现了c2dm,它可以正常工作,接收消息和一切.
然而,有一个问题我无法找到解决方案.

当某个事件发生时,我想快速将相同的消息推送到几千个设备,最好是在一分钟内.我知道无法确定是否会传递此消息,并且Google可能会因不同情况而延迟发送消息.

我的iOS实现大致相同,当然发送部分除外.对于15000条消息,大约需要5秒.对于5000条到Android的消息,它需要一个多小时才能实现.

有谁知道加速这个的方法？
或谷歌是否停止这种大规模推动以阻止垃圾邮件？

代码的C2DM部分如下.这是在PHP中,但我读大多数其他编程语言没有问题.
我使用脚本连接()一次然后循环所有标记并使用sendMessage()发送每条消息.发送完所有消息后,它会断开连接().

PHP
class C2DMclient
{
    private $authKey = NULL;
    private $ch = NULL;

    function connect() {
        $post_params = array(
            'Email'       => 'C2DM_USER','Passwd'      => 'C2DM_PWD','accountType' => 'HOSTED_OR_GOOGLE','source'      => 'appname','service'     => 'ac2dm',);
        $first = true;
        $data_msg = '';

        foreach($post_params as $key => $value) {
            if($first)
                $first = false;
            else
                $data_msg .= '&';

            $data_msg .= urlencode($key).'='.urlencode($value);
        }

        $x = curl_init('C2DM_CLIENTLOGIN');
        curl_setopt($x,CURLOPT_HEADER,true);
        curl_setopt($x,CURLOPT_POST,CURLOPT_POSTFIELDS,$data_msg);
        curl_setopt($x,CURLOPT_RETURNTRANSFER,true);
        $response = curl_exec($x);
        curl_close($x);

        $pos = strpos($response,'Auth=');
        $this->authKey = trim(substr($response,5 + $pos));
        $this->ch = curl_init();
        curl_setopt($this->ch,CURLOPT_URL,'C2DM_SERVER');
    }

    function disconnect() {
        curl_close($this->ch);
        $this->authKey = NULL;
    }

    function sendMessage($deviceToken,$message) {
        $data = array(
            'registration_id' => $deviceToken,'collapse_key'    => 'ck_type','data.type'       => 'TYPE','data.message'    => $message,'data.title'      => 'Title'
        );
        $headers = array('Authorization: GoogleLogin auth='.$this->authKey);

        if($headers)
            curl_setopt($this->ch,CURLOPT_HTTPHEADER,$headers);

        curl_setopt($this->ch,CURLOPT_SSL_VERIFYPEER,0);
        curl_setopt($this->ch,true);
        curl_setopt($this->ch,$data);

        $messagedata = curl_exec($this->ch);
            return TRUE;
    }
}
?>

编辑：
新解决方案基于curl_multi_exec.

在循环遍历数据库查询结果时收集卷曲句柄.在收集了几百个卷曲句柄之后,调用sendMessages($chs)来发送所有这些消息.目前我在发送之前收集了700条消息,并且似乎具有良好的传送速度和足够快,~10秒发送5000条消息.数字越大似乎会影响交付率.

PHP
class C2DMclient
{
    private $authKey = NULL;
    private $ch = NULL;

    function connect() {
        $post_params = array(
            'Email'       => 'C2DM_USER',5 + $pos));
    }

    function getMessageCurlHandle($deviceToken,$message) {
        $ch = curl_init();
        curl_setopt($ch,'C2DM_SERVER');
        $data = array(
            'registration_id' => $deviceToken,'data.title'      => 'Title'
        );
        $headers = array('Authorization: GoogleLogin auth='.$this->authKey);

        if($headers)
            curl_setopt($ch,$headers);
        curl_setopt($ch,0);
        curl_setopt($ch,true);
        curl_setopt($ch,$data);
        return $ch;
    }

    function sendMessages($chs) {
        $mh = curl_multi_init();
        foreach($chs as $ch) {
            curl_multi_add_handle($mh,$ch);
        }
        $active = null;
        do {
            $mrc = curl_multi_exec($mh,$active);
        } while($mrc == CURLM_CALL_MULTI_PERFORM);

        while($active && $mrc == CURLM_OK) {
            if(curl_multi_select($mh) != -1) {
                do {
                    $mrc = curl_multi_exec($mh,$active);
                } while($mrc == CURLM_CALL_MULTI_PERFORM);
            }
        }
        curl_multi_close($mh);
    }
}
