基于swoole_server的简单Http服务器
<?php
//1.构建Server对象
$serv = new swoole_server("0.0.0.0", 9501);
//2.设置运行时参数
$serv->set(array(
'worker_num' => 8,
'daemonize' => 0,
'max_request' => 10000,
'dispatch_mode' => 2,
'debug_mode'=> 1,
));
//3.注册事件回调函数
$serv->on('Receive', function($serv, $fd, $from_id, $data){
$respData='<h1>Hello Swoole.</h1>';
response($serv,$fd,$respData);//封装并发送HTTP响应报文
});
//4.启动服务器
$serv->start();
/**
* 发送内容
* @param \swoole_server $serv
* @param int $fd
* @param string $respData
* @return void
*/
function response($serv,$fd,$respData){
//响应行
$response = array(
'HTTP/1.1 200',
);
//响应头
$headers = array(
'Server'=>'SwooleServer',
'Content-Type'=>'text/html;charset=utf8',
'Content-Length'=>strlen($respData),
);
foreach($headers as $key=>$val){
$response[] = $key.':'.$val;
}
//空行
$response[] = '';
//响应体
$response[] = $respData;
$send_data = join("\r\n",$response);
$serv->send($fd, $send_data);
}
