transport屬性

要求（workerman >= 3.3.4）

設(shè)置傳輸屬性，可選值為 tcp 和 ssl，默認(rèn)是tcp。

transport為 ssl 時(shí)，要求PHP必須安裝openssl擴(kuò)展。

當(dāng)把Workerman作為客戶端向服務(wù)端發(fā)起ssl加密連接(https連接、wss連接等)時(shí)請(qǐng)?jiān)O(shè)置此選項(xiàng)為ssl，例如下面的例子。

示例 (https連接)

use Workerman\Worker;
use Workerman\Connection\AsyncTcpConnection;
use Workerman\Connection\TcpConnection;
require_once __DIR__ . '/vendor/autoload.php';

$task = new Worker();
// 進(jìn)程啟動(dòng)時(shí)異步建立一個(gè)到www.baidu.com連接對(duì)象，并發(fā)送數(shù)據(jù)獲取數(shù)據(jù)
$task->onWorkerStart = function($task)
{
    $connection_to_baidu = new AsyncTcpConnection('tcp://www.baidu.com:443');

    // 設(shè)置為ssl加密連接
    $connection_to_baidu->transport = 'ssl';

    $connection_to_baidu->onConnect = function(AsyncTcpConnection $connection_to_baidu)
    {
        echo "connect success\n";
        $connection_to_baidu->send("GET / HTTP/1.1\r\nHost: www.baidu.com\r\nConnection: keep-alive\r\n\r\n");
    };
    $connection_to_baidu->onMessage = function(AsyncTcpConnection $connection_to_baidu, $http_buffer)
    {
        echo $http_buffer;
    };
    $connection_to_baidu->onClose = function(AsyncTcpConnection $connection_to_baidu)
    {
        echo "connection closed\n";
    };
    $connection_to_baidu->onError = function(AsyncTcpConnection $connection_to_baidu, $code, $msg)
    {
        echo "Error code:$code msg:$msg\n";
    };
    $connection_to_baidu->connect();
};

// 運(yùn)行worker
Worker::runAll();
