我正在尝试使用 Firebase 和 pyfcm https://pypi.python.org/pypi/pyfcm/发送推送通知 。但我想知道如何发送带有通知的图像，因为在参数中搜索没有选项

这是pyfcm的文档代码：

def notify_multiple_devices(self,
                            registration_ids=None,
                            message_body=None,
                            message_title=None,
                            message_icon=None,
                            sound=None,
                            condition=None,
                            collapse_key=None,
                            delay_while_idle=False,
                            time_to_live=None,
                            restricted_package_name=None,
                            low_priority=False,
                            dry_run=False,
                            data_message=None,
                            click_action=None,
                            badge=None,
                            color=None,
                            tag=None,
                            body_loc_key=None,
                            body_loc_args=None,
                            title_loc_key=None,
                            title_loc_args=None,
                            content_available=None,
                            extra_kwargs={}):

那么我应该使用哪个参数来发送 url 图像？

谢谢

我制作应用程序,您可以在其中设置闹钟.例如,我星期一早上7点钟上课,所以我需要每周一开始报警,但周二还有另一节课,必须这样做.

我已经可以做到这一点并且工作,每个curso发出警报,但是当我重新启动手机时,它们就无法工作.

这是我的代码,put extra在我的应用程序中非常重要:

Calendar cal = Calendar.getInstance();
    cal.setTimeInMillis(System.currentTimeMillis());
    cal.set(Calendar.HOUR_OF_DAY, horai);
    cal.set(Calendar.MINUTE, minutoi);
    cal.set(Calendar.DAY_OF_WEEK, dias.getSelectedItemPosition() + 1);
    cal.add(Calendar.SECOND, 2);



    Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
    intent.putExtra("name", curso);
    //intent.putExtra("curos bn",1);
    PendingIntent pendingIntent =
           PendingIntent.getBroadcast(getBaseContext(),
           cont, intent, PendingIntent.FLAG_UPDATE_CURRENT );//cont star with 1 a then ++

接收器

public class AlarmReceiver extends BroadcastReceiver {

private static final String TAG = "BANANEALARM";
Intent intent;
PendingIntent pendingIntent;
NotificationManager notificationManager;
private static final int PERIOD=5000;
@Override
public void onReceive(Context context, Intent intent) {



    Log.i(TAG, "BroadcastReceiver has received …
