如何在Laravel中使用Kreait / Firebase云消息向多个设备发送发送推送通知

Question

I'm trying to send a push notification to specific device (more than 1 device)

I've tried

$device = array('device1','device2');

but error Kreait\\Firebase\\Messaging\\CloudMessage::withTarget() must be of the type string, array given

Also has tried

$device = 'device1,device2';

Also got an error. On the api document, it doesn't mention about format to send to multiple device.

Anyone can help?

需要发送JSON数组，只需json_encode此数组。
