通过fcm实现消息推送

public static function sendMessages() {
    try {
        //准备配置
        $url = 'https://fcm.googleapis.com/fcm/send';
        $api_key = 'AIzaSyBIteo6XFgX_xxxx';

        $data = [

            'noticeType' => xxx,
        ];
        $fields = array(
            //群发使用registration_ids[为数组]  单个用户使用to
            //'to'             => xxx
            'registration_ids' => xxx,  
            'data'             => $data,
            'time_to_live'     => xxx,
        );
        $headers = array(
            'Authorization: key=' . $api_key,
            'Content-Type: application/json'
        );
        // Open connection
