# 作为ws/wss客户端 # 作为ws/wss客户端 有时候需要让workerman作为客户端以ws/wss协议去连接某个服务端，并与之交互。 以下是示例。 1、workerman作为ws客户端 ```php <?php use Workerman\Worker; use Workerman\Connection\AsyncTcpConnection; require_once __DIR__ . '/../Workerman/Autoloader.php'; $worker = new Worker(); $worker->onWorkerStart = function($worker){ $con = new AsyncTcpConnection('ws://echo.websocket.org:80'); $con->onConnect = function($con) { $con->send('hello'); }; $con->onMessage = function($con, $data) { echo $data; }; $con->connect(); }; Worker::runAll(); ``` 2、workerman作为wss(ws+ssl)客户端 ```php <?php use Workerman\Worker; use Workerman\Connection\AsyncTcpConnection; require_once __DIR__ . '/../Workerman/Autoloader.php'; $worker = new Worker(); $worker->onWorkerStart = function($worker){ // ssl需要访问443端口 $con = new AsyncTcpConnection('ws://echo.websocket.org:443'); // 设置以ssl加密方式访问，使之成为wss $con->transport = 'ssl'; $con->onConnect = function($con) { $con->send('hello'); }; $con->onMessage = function($con, $data) { echo $data; }; $con->connect(); }; Worker::runAll(); ``` 3、workerman作为wss(ws+ssl)客户端（需要本地ssl证书） ```php <?php use Workerman\Worker; use Workerman\Connection\AsyncTcpConnection; require_once __DIR__ . '/../Workerman/Autoloader.php'; $worker = new Worker(); $worker->onWorkerStart = function($worker){ // 设置访问对方主机的本地ip及端口以及ssl证书 $context_option = array( // ssl选项，参考http://php.net/manual/zh/context.ssl.php 'ssl' => array( // 本地证书路径。 必须是 PEM 格式，并且包含本地的证书及私钥。 'local_cert' => '/your/path/to/pemfile', // local_cert 文件的密码。 'passphrase' => 'your_pem_passphrase', // 是否允许自签名证书。 'allow_self_signed' => true, // 是否需要验证 SSL 证书。 'verify_peer' => false ) ); // ssl需要访问443端口 $con = new AsyncTcpConnection('ws://echo.websocket.org:443', $context_option); // 设置以ssl加密方式访问，使之成为wss $con->transport = 'ssl'; $con->onConnect = function($con) { $con->send('hello'); }; $con->onMessage = function($con, $data) { echo $data; }; $con->connect(); }; Worker::runAll(); ```
