1、用的是TP5.1的框架，swoole分成一个客户端发送接收消息，一个服务器负责处理信息
服务端代码，服务器要先安装swoole拓展，用 php server.php 启动进程监听
推荐（免费）：swoole

$server = new Swoole();2、客户端请求，可以通过api访问
function send_tem_to(){
$type = input('type'); // 0 按人头算 1 按标签算 2 全部粉丝
$target = input('target/s');
$field = input('fields/s');
$tem_id = input('tem_id');//模板ID，字符串
$url = input('url','');
$client = new swoole_client(SWOOLE_SOCK_TCP);//创建同步TCP
if (!$client->connect('127.0.0.1', 9501, 0.5))//链接
{
exit("connect failed. Error: {$client->errCode}
");
}
$client->send(json_encode(array('appid'=>$this->appid,'uid'=>$this->uid,'tem_id'=>$tem_id,'data'=>$field))); //发送请求
$rec = $client->recv();//接收返回数据
$client->close();//关闭链接
}
