Question

我一直在使用firebase fcm向我的应用中的Android用户发送推送通知。通常推送通知工作正常。但是，无论我通过刷卡打开或关闭消息多少次，有时同一消息仍会反复显示在应用程序上。应用程序没有任何问题，因为当从互联网断开连接时消息停止。我很困惑它是不是它的firebase故障还是我的代码问题，因为它只会在某个时候发生。

以下是用于发送推送通知的代码：

public function android_notification_by_fcm($android_users, $message)
{
    $device_tokens = array();
    if (!empty($android_users)) {
        foreach ($android_users as $android_use) {
            array_push($device_tokens, $android_use->reg_id);
        }

        $url = "https://fcm.googleapis.com/fcm/send";
        // $notification = "";
        $fields = array(
            'registration_ids' => $device_tokens,
            'data' => $message
        );


        $fields = json_encode($fields);
        $headers = array(
            'Authorization:key = secretkey',
            'Content-Type: application/json'
        );
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, TRUE);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
        $result = json_decode(curl_exec($ch));
        if ($result) {
            foreach ($result->results as $res) {
                if (isset($res->error)) {
                    \Log::warning('android sending notification for detail version failed due to: ' . $res->error);
                } else {
                    \Log::info('android sending notification for detail version success. Message id is: ' . $res->message_id);
                }
            }
        }
        curl_close($ch);
        return 1;

    } else {
        return 2;
    }
