环境应用 Docker：
在 docker 中搭建 swoole 运行环境
服务器端应用后面文章中的代码：
在 Swoole 中应用 WebSocket 服务端和客户端
测试程序代码：
<?phpuse Swoole\Coroutine\Channel;use Swoole\Coroutine\Http\Client;use function Swoole\Coroutine\run;class Test{ protected $request; //总申请量 protected $requested = 0; protected $start_time; protected $channel; function __construct() { $this->request = 5000; $this->channel = new Channel($this->request); } public function run() { $this->start_time = microtime(true); $this->webSocket(); } protected function webSocket() { // 创立一个协程容器 run(function () { for ($i = 0; $i < $this->request; $i++) { // 开启一个协程 go(function() use ($i) { $cli = new Client('127.0.0.1', 8081); $cli->set(['websocket_mask' => false]); $ret = $cli->upgrade('/'); if ($ret) { $ret = $cli->push('1 Hello World'); $this->channel->push([$i => $cli->recv(1)]); } }); } $this->finish(); }); } protected function finish() { for ($i = 1; $i <= $this->request; $i++) { $this->channel->pop(); $this->requested++; } $cost_time = round(microtime(true) - $this->start_time, 4); echo "Request num:" . $this->request.PHP_EOL; echo "Success num:" . $this->requested.PHP_EOL; echo "Total time:" . $cost_time.PHP_EOL; echo "Request per second:" . intval($this->request / $cost_time).PHP_EOL; }}$test = new Test();$test->run();测试后果：
