swoole多端口监听
今天测试swoole写webserver实现多端口监听。记录下爬过的坑:关于tcp协议监听触发不到receive!!!!!
首先上服务端代码
class Http
{
/**
* 服务实例
* @var Server
*/
protected $server;
public function run(){
$setting = Config::get('http');
/*开启监听*/
$this->server = new Server($setting['host'],$setting['port']);
if (isset($setting['config']) && $setting['config'])$this->server->set($setting['config']);
if (isset($setting['tcp_check']) && $setting['tcp_check']){
/*开启多端口监听*/
$port = $this->server->addListener('127.0.0.1','9501',SWOOLE_SOCK_TCP);
$port->on('connect',[$this,'connect']);
$port->on('receive',[$this,'receive']);
}
$this->server->on('start',[$this,'start']);
$this->server->on('request',[$this,'request']);
$this->server->on('workerStart',[$this,'workerStart']);
$this->server->start();
}
/**
* 主进程启动
* @param Server $server
*/
public function start(Server $server){
$reload = Reload::getInstance(Config::get('reload_watch'));
/*启动定时热重启检测*/
swoole_timer_tick(6000,function ()use ($reload){
if ($reload->reload()) $this->server->reload();
});
}
/**
*
* @param Request $request
* @param Response $response
*/
public function request(Request $request,Response $response){
$route = Route::get_instance();
$route->dispatch($request,$response);
}
public function workerStart(Server $server, int $worker_id){
/*可热重启配置*/
Config::loadLazy();
/*加载路由*/
include_once APP_PATH.'/route.php';
}
public function connect(Server $server,int $fd, int $reactorId){
var_dump('connection');
}
public function receive(Server $server, int $fd, int $reactor_id, string $data){
var_dump('receive',$data);
}
}
当我调用本地tcp client向服务发送tcp请求并发送数据的时候发现如下结果:
[root@bin]# php walter.php
string(10) "connection"
发现没,tcp监听服务只触发了connect回调,receive回调竟然没有触发成功。经过不断调试后来在官网看到如下一段话得到了启发。
官网说增加监听端口需要单独调用set函数来为addListener返回的swoole_server_port对象设置监听配置注意,只对1.8.0以上版本有效
后来在开启多端口监听中加入了$port->set([]);这一行后发现监听服务可以顺利监听到并且成功触发了recrive
public function run(){
$setting = Config::get('http');
/*开启监听*/
$this->server = new Server($setting['host'],$setting['port']);
if (isset($setting['config']) && $setting['config'])$this->server->set($setting['config']);
if (isset($setting['tcp_check']) && $setting['tcp_check']){
/*开启多端口监听*/
$port = $this->server->addListener('127.0.0.1','9501',SWOOLE_SOCK_TCP);
$port->set([]);
$port->on('connect',[$this,'connect']);
$port->on('receive',[$this,'receive']);
}
$this->server->on('start',[$this,'start']);
$this->server->on('request',[$this,'request']);
$this->server->on('workerStart',[$this,'workerStart']);
$this->server->start();
}
收到结果如下:
[root@bin]# php walter.php string(10) "connection" string(7) "receive" string(11) "hello world"
虽然不知道这个是不是swoole目前的bug,官网上暂时没看到类似的问题跟文档说明。但是这个是实实在在需要注意的。每一个server都必须调用set函数设置需要的配置,哪怕你什么都不想要设置都要给个空数组进去以防万一。
另外还有一个需要注意的当监听多端口的时候swoole_server_port->set()设置worker_num数量的时候这里的worker进程不会另外创建,应该是从主进程创建的worker中创建的worker中分配相应数量的进程给swoole_server_port的。所以这里设置的数量比主进程设置的多是没有用的。主进程设置生成的worker数量是多少就多少。以上只是个人猜测,至于swoole底层如何处理这个swoole_server_port设置的worker_num配置不得而知,还没真正看过底层的实现代码。也有人的说法是swoole_server_port设置worker_num是不生效的。哪种说法正确只有以后有机会看看底层源码来判断了。或许这个也是当前版本的bug也说不定。
当前测试的swoole版本为4.2.8
