怎么在PHP中使用swoole編寫一個echo服務器?相信很多沒有經驗的人對此束手無策,為此本文總結了問題出現的原因和解決方法,通過這篇文章希望你能解決這個問題。
server.php代碼如下:
<?php class EchoServer { protected $serv = null; public function __construct() { $this->serv = new swoole_server('0.0.0.0', 8888); //配置參數 $this->serv->set(array( 'worker_num' => 4, 'daemonize' => 0, )); //注冊回調函數 $this->serv->on('start', array($this, 'start')); $this->serv->on('connect', array($this, 'connect')); $this->serv->on('receive', array($this, 'receive')); $this->serv->on('close', array($this, 'close')); //啟動服務 $this->serv->start(); } public function start($serv) { echo "start \n"; } //有客戶端連接時 public function connect($serv, $fd) { echo "connect \n"; $serv->send($fd, "hello \n"); } public function close($serv, $fd) { echo "close \n"; } public function receive($serv, $fd, $from_id, $data) { echo "get message {$fd} : {$data} \n"; //向客戶端發送信息 $serv->send($fd, $data . "\n"); } } $serv = new EchoServer();
client.php代碼如下:
<?php class EchoClient { protected $client = null; public function __construct() { //注意這里需設置為異步,不然下面無法設置事件回調函數 $this->client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC); $this->client->on('connect', array($this, 'connect')); $this->client->on('receive', array($this, 'receive')); $this->client->on('close', array($this, 'close')); $this->client->on('error', array($this, 'error')); //連接服務端 $this->client->connect('0.0.0.0', 8888); } public function connect($client) { echo "connect \n"; } public function receive($client, $data) { echo "server send: {$data}"; //向標準輸出寫入數據 fwrite(STDOUT, "請輸入消息:"); //獲取標準輸入數據 $msg = trim(fgets(STDIN)); //向服務端發送數據 $client->send($msg); } public function close($client) { echo "close \n"; } public function error($client) { echo "error \n"; } } $cli = new EchoClient();
然后分別運行這兩個腳本
> /data/php56/bin/php server.php > /data/php56/bin/php client.php
運行結果如下:
