WorkerMan 最简单的推送

服务端

use Workerman\Lib\Timer;
use Workerman\Worker;

require_once __DIR__ . '/../../vendor/autoload.php';

// 心跳间隔55秒
define('HEARTBEAT_TIME', 5500);

$worker = new Worker('websocket://0.0.0.0:1415');
$worker->count = 1;
$connections = []; //uid和connection绑定关系

$worker->onWorkerStart = function ($worker) {
    Timer::add(1, function () use ($worker) {
        $time_now = time();
        foreach ($worker->connections as $connection) {
            // 有可能该connection还没收到过消息，则lastMessageTime设置为当前时间
            if (empty($connection->lastMessageTime)) {
                $connection->lastMessageTime = $time_now;
                continue;
            }
            // 上次通讯时间间隔大于心跳间隔，则认为客户端已经下线，关闭连接
            if ($time_now - $connection->lastMessageTime > HEARTBEAT_TIME) {
                $connection->close();
            }
        }
    });
    $inner_text_worker = new Worker('text://127.0.0.1:5678');
    //这里的$connection是给推送者调用的
    $inner_text_worker->onMessage = function ($connection, $buffer) {
        $data = json_decode($buffer, true);
        $uid = $data['uid'];
        // 通过workerman，向uid的页面推送数据
        $ret = sendMessageByUid($uid, $data['msg']);
        // 返回推送结果
        $connection->send($ret ? 'ok' : 'fail');
    };
    $inner_text_worker->listen();
};



//连接上立马发送一个init包，绑定uid和connection
$worker->onMessage = function ($connection, $data) {
    global $worker;
    $connection->lastMessageTime = time();
    $json = json_decode($data, true);
    if ($json['type'] == 'init') {
        bindUidConnection($json['uid'], $connection);
        $connection->uid = $json['uid'];
        $connection->send("绑定成功");
    } else {
        $connection->send("ping");
    }
};

$worker->onClose = function ($connection) {
    global $worker;
    global $connections;
    if (isset($connection->uid)) {
        // 连接断开时删除映射
        unset($connections[$connection->uid]);
    }
};
function bindUidConnection($uid, $connection)
{
    global $connections;
    if (!isset($connections[$uid])) {
        $connections[$uid] = $connection;
    }
}

function sendMessageByUid($uid, $message)
{
    global $worker;
    global $connections;
    if (isset($connections[$uid])) {
        $connection = $connections[$uid];
        $connection->send($message);
        return true;
    }

}
Worker::runAll();

推送端

$client = stream_socket_client('tcp://127.0.0.1:5678', $errno, $errmsg, 1);
print_r($client);
// 推送的数据，包含uid字段，表示是给这个uid推送
$data = array('uid' => 100, 'msg' => '你好');
// 发送数据，注意5678端口是Text协议的端口，Text协议需要在数据末尾加上换行符
fwrite($client, json_encode($data) . "\n");
// 读取推送结果
echo "推送消息\n";
echo fread($client, 8192);
