//消息推送
function notice_message_push($data){

//     $tag = '"all"';  发给所有用户//     $tag = '{"tag":["'.$uid.'"]}';   发给部分用户
//     $data = '{"platform": "all","audience" :'.$tag.',"notification":{"android" : {"alert" : "'.$content.'", "title":"'.$title.'","sound":"default", "badge":"+1","extras":{"newsid":321}},"ios":{"alert":"'.$content.'","title":"'.$title.'","sound":"default","badge":"+1","extras":{"newsid":321}}},"options":{"time_to_live":60,"apns_production":false}}';
    $url= "https://api.jpush.cn/v3/push";

// 启动一个CURL会话
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
