介绍swoole异步群发模板消息

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

run()->send();

//require_once __DIR__ . '/../../../thinkphp/helper.php';
use think\cache\driver\Redis;
//use think\Controller;
use think\Db;

        $new_field = $list['field'];

        $result = file_get_contents($url, false, $context);

        return $result;
    }



}

$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}\n");
        }


            $client->send(json_encode(array('appid'=>$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
        
    }
