腾讯云推送的文档，没有 php 的 sdk，只好自己写了

<?php

use App\Models\User;

class Push
{
//腾讯的推送服务，安卓和ios两个端对应是两个应用，当后端推送时，无法知道用户是ios设备还是安卓设备，只能两端都发送一下

}

使用如下：

$push = new \App\Utility\Push();
$push->sendToIos($this->user_id,$this->title,$this->content,$this->params);
$push->sendToAndroid($this->user_id,$this->title,$this->content,$this->params);
