LNMP swoole 的初步使用

1、安装swoole扩展

# 编译安装
# https://github.com/swoole/swoole-src/releases clone一份下来
cd swoole
sudo phpize (ubuntu 没有安装phpize可执行命令：sudo apt-get install php-dev来安装phpize)
sudo ./configure
sudo make 
sudo make install

# pecl安装
pecl install swoole
sudo vim /etc/php/7.2/mods-available/swoole.ini
# 内容 写上： extension=/usr/lib/php/20170718/swoole.so (pecl安装之后有给你显示扩展安装的位子)
sudo ln -s /etc/php/7.2/mods-available/swoole.ini /etc/php/7.2/cli/conf.d/20-swoole.ini

2、使用swoole

TCP client 端
<?php
$client = new swoole_client(SWOOLE_TCP | SWOOLE_KEEP); //同步阻塞
$ret = $client->connect('127.0.0.1', 9906);
if(!$ret)
{
    echo "Connect Server fail.errCode=".$client->errCode;
}
else
{
    fwrite(STDOUT,'请输入');
    $msg = trim(fgets(STDIN));
    $client->send($msg);
    $result = $client->recv(65535,swoole_client::MSG_PEEK | swoole_client::MSG_WAITALL); // 接收server过来的东西
    echo $result;
}
TCP server 端
<?php
$serv = new swoole_server('0.0.0.0', 9906, SWOOLE_BASE, SWOOLE_SOCK_TCP);

//设置事件回调函数
$serv->on('connect', function ($serv, $fd) {
    echo "Client:Connect.\n";
});

// 接受函数
$serv->on('receive', function ($serv, $fd, $reactor_id, $data) {
    echo 'cli：'.$data."\n";
    $serv->send($fd, 'server: ' . $data."\n");
    $serv->close($fd);
});

$serv->on('close', function ($serv, $fd) {
    echo "Client: Close.\n";
});

//启动服务器
$serv->start();
websocker client端 （使用JQ发送）

    var ws = new WebSocket("ws://127.0.0.1:9906");
    ws.onopen = function()

        ws.send("hello")
    };
    ws.onmessage = function(evt)
    {
        console.log(evt.data)
    };
    ws.onclose = function(evt)
    {
        console.log("WebSocketClosed!");
    };
    ws.onerror = function(evt)
    {
        console.log("WebSocketError!");
    };

    $('#send_btn').click(function (_this) {
        var sendMsg = $('#send_msg').val()
        if(sendMsg == ''){
            alert('请发送消息')
            return
        }
        ws.send(sendMsg)
    })
</script>
</html>
websocker server 端
<?php
$server = new swoole_websocket_server("127.0.0.1", 9906);

$server->set(array(
    'worker_num' => 8,
    'max_request' => 10000,
    'max_conn' => 100000,
    'dispatch_mode' => 2,
    'debug_mode'=> 0,
    'daemonize' => false,
    'log_level' => SWOOLE_LOG_ERROR, // 日志等级 关闭开启debug
    'trace_flags' => SWOOLE_TRACE_SERVER, // 日志等级 关闭开启debug
));

$server->on('open', function (swoole_websocket_server $server, $request) {
    echo "server: handshake success with fd:{$request->fd}\n"; // 客户端链接则执行
});

$server->on('message', function (swoole_websocket_server $server, $frame) {
    // 客户端发送信息则执行
    echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n";
    foreach ($server->connections as $fd){
        $server->push($fd, "this is server:".$frame->data);
    }
//    $server->push($frame->fd, "this is server:".$frame->data);

});

$server->on('close', function ($ser, $fd) {
    echo "client {$fd} closed\n";
});

$server->start();
websocker client 端 （自己测试用的一个破IM）

    };
    ws.onerror = function(evt)

        console.log("WebSocketError!");
    };

    $('#send_btn').click(function (_this) {
        var sendMsg = $('#send_msg').val();
        var user = $('#user').val();
        if(sendMsg == ''){
            alert('请发送消息');
            return
        }else if (user){
            var arr = [ 'push',user,sendMsg, ];
        }else{
            var arr = [ 'message',sendMsg, ];
        }
        ws.send(arr)


    });

    $('#set_btn').click(function (_this) {
        var sendMsg = $('#name').val();
        var arr = [ 'set_name',sendMsg, ];
        // JSON.stringify( arr );
        if(sendMsg == ''){
            alert('请写上昵称消息');
            return
        }
        ws.send(arr)
    });
