__construct 方法

void AsyncUdpConnection::__construct(string $remote_address)

創(chuàng)建一個udp連接對象。

AsyncUdpConnection可以讓W(xué)orkerman作為客戶端與遠(yuǎn)程服務(wù)端傳輸udp數(shù)據(jù)。

參數(shù)

參數(shù):remote_address

連接的地址，例如
udp://192.168.1.1:1234
frame://192.168.1.1:8080
text://192.168.1.1:8080

示例

use Workerman\Worker;
use Workerman\Connection\AsyncUdpConnection;
use Workerman\Timer;
require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker('udp://0.0.0.0:1234');
$worker->onWorkerStart = function(){
    // 1秒后啟動一個udp客戶端，連接1234端口并發(fā)送字符串 hi
    Timer::add(1, function(){
        $udp_connection = new AsyncUdpConnection('udp://127.0.0.1:1234');
        $udp_connection->onConnect = function($udp_connection){
            $udp_connection->send('hi');
        };
        $udp_connection->onMessage = function($udp_connection, $data){
            // 收到服務(wù)端返回的數(shù)據(jù) hello
            echo "recv $data\r\n";
            // 關(guān)閉連接
            $udp_connection->close();
        };
        $udp_connection->connect();
    }, null, false);
};
$worker->onMessage = function($connection, $data)
{
    // 收到AsyncUdpConnection客戶端發(fā)來的數(shù)據(jù)，返回字符串 hello
    $connection->send("hello");
};
Worker::runAll();             

執(zhí)行后打印類似:

recv hello
