ws協(xié)議

目前Workerman的ws協(xié)議版本為13。

workerman可以作為客戶端，通過ws協(xié)議發(fā)起websocket連接，連到遠(yuǎn)程websocket服務(wù)器，實(shí)現(xiàn)雙向通訊。

注意
ws協(xié)議只能通過AsyncTcpConnection作為客戶端使用，不能作為websocket服務(wù)端監(jiān)聽協(xié)議。也就是說以下寫法是錯(cuò)誤的。

$worker = new Worker('ws://0.0.0.0:8080');

如果想用workerman作為websocket服務(wù)端，請(qǐng)使用websocket協(xié)議。

ws作為websocket客戶端協(xié)議示例：

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

use Workerman\Protocols\Ws;
use Workerman\Worker;
use Workerman\Connection\AsyncTcpConnection;

$worker = new Worker();
// 進(jìn)程啟動(dòng)時(shí)
$worker->onWorkerStart = function()
{
    // 以websocket協(xié)議連接遠(yuǎn)程websocket服務(wù)器
    $ws_connection = new AsyncTcpConnection("ws://127.0.0.1:1234");
    // 每隔55秒向服務(wù)端發(fā)送一個(gè)opcode為0x9的websocket心跳(可選)
    $ws_connection->websocketPingInterval = 55;
    // 設(shè)置http頭(可選)
    $ws_connection->headers = [
        'Cookie' => 'PHPSID=82u98fjhakfusuanfnahfi; token=2hf9a929jhfihaf9i',
        'OtherKey' => 'values'
    ];
    // 設(shè)置數(shù)據(jù)類型(可選)
    $ws_connection->websocketType = Ws::BINARY_TYPE_BLOB; // BINARY_TYPE_BLOB為文本 BINARY_TYPE_ARRAYBUFFER為二進(jìn)制
    // 當(dāng)TCP完成三次握手后(可選)
    $ws_connection->onConnect = function($connection){
        echo "tcp connected\n";
    };
    // 當(dāng)websocket完成握手后(可選)
    $ws_connection->onWebSocketConnect = function(AsyncTcpConnection $con, $response) {
        echo $response;
        $con->send('hello');
    };
    // 遠(yuǎn)程websocket服務(wù)器發(fā)來消息時(shí)
    $ws_connection->onMessage = function($connection, $data){
        echo "recv: $data\n";
    };
    // 連接上發(fā)生錯(cuò)誤時(shí)，一般是連接遠(yuǎn)程websocket服務(wù)器失敗錯(cuò)誤(可選)
    $ws_connection->onError = function($connection, $code, $msg){
        echo "error: $msg\n";
    };
    // 當(dāng)連接遠(yuǎn)程websocket服務(wù)器的連接斷開時(shí)(可選，建議加上重連)
    $ws_connection->onClose = function($connection){
        echo "connection closed and try to reconnect\n";
        // 如果連接斷開，1秒后重連
        $connection->reConnect(1);
    };
    // 設(shè)置好以上各種回調(diào)后，執(zhí)行連接操作
    $ws_connection->connect();
};
Worker::runAll();
