GCM设置推送通知的到期日期

Question

我正在使用PHP成功为我的Android用户发送GCM推送通知,但我想为我的推送通知设置过期日期,这样如果用户1周没有互联网连接,它将不会收到旧的推送通知.我怎么能实现它.

谢谢.

这是php代码:

 private $GOOGLE_API_KEY = "XXXXX";

    public function send($registration_id, $data) {
        // include config
        // Set POST variables
        $url = 'https://android.googleapis.com/gcm/send';
        $fields = array(
            'registration_ids' => $registration_id,
            'data' => $data,
        );
        $headers = array(
            'Authorization: key=' . $this->GOOGLE_API_KEY,
            '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;
    }

time_to_live发送时你正在设置一个参数.值以秒为单位(仅低于一分钟)

$fields = array(
        'registration_ids' => $registration_id,
        'data' => $data,
        'time_to_live' => 60
    );

您可以使用发送请求中的time_to_live参数指定消息的最长生命周期.此参数的值必须是0到2,419,200秒的持续时间,它对应于GCM将存储并尝试传递消息的最长时间.不包含此字段的请求默认为最长4周.
