Kemas kini hangat
Apabila pelayan swoole sedang berjalan, fail php berjalan dalam memori pemastautin, supaya anda boleh mengelakkan pembacaan berulang cakera, tafsiran berulang dan kompilasi php, untuk mencapai prestasi tertinggi, jadi mengubah suai kod memerlukan memulakan semula perkhidmatan
Pelanjutan think-swoole menyediakan fungsi kemas kini panas secara automatik selepas mengesan kemas kini pada fail yang berkaitan tidak perlu melengkapkan mula semula secara manual, yang sesuai untuk pembangunan dan penyahpepijatan
Pengeluaran Tidak disyorkan untuk memulakan pemantauan fail dalam persekitaran ini, kerana ia akan menyebabkan kehilangan prestasi Dalam keadaan biasa, fail yang anda ubah suai perlu disahkan sebelum pengerahan kemas kini
.envTetapan dalam APP_DEBUG = true akan mendayakan kemas kini panas secara lalai
'hot_update' => [
'enable' => env('APP_DEBUG', false),
'name' => ['*.php'],
'include' => [app_path()],
'exclude' => [],
],
Penerangan Parameter

websocket
先来一个官方的例子
$server = new Swoole\WebSocket\Server("0.0.0.0", 9501);
$server->on('open', function (Swoole\WebSocket\Server $server, $request) {
echo "server: handshake success with fd{$request->fd}\n";
});
$server->on('message', function (Swoole\WebSocket\Server $server, $frame) {
echo "receive from {$frame->fd}:{$frame->data}\n";
$server->push($frame->fd, "this is server");
});
$server->on('close', function ($ser, $fd) {
echo "client {$fd} closed\n";
});
$server->start();
开启think-swoole的websocket功能 \config\swoole.php
'websocket' => [ 'enable' => true, ],
创建三个事件
php think make:listener SwWsConnect php think make:listener SwWsClose php think make:listener SwWsMessage
然后将这三个事件写到到事件监听中，分别有以下2中文件可以修改方式，注意二选一
thinkphp6自带的事件绑定app\event.php
'listen' => [ ........ // 监听链接 'swoole.websocket.Connect' => [ \app\listener\SwWsConnect::class ], //关闭连接 'swoole.websocket.Close' => [ \app\listener\SwWsClose::class ], //发送消息场景 'swoole.websocket.Message' => [ \app\listener\SwWsMessage::class ] ],
think-swoole事件绑定config\swoole.php
'listen' => [ 'connect'=>\app\listener\SwWsConnect::class, 'close'=>\app\listener\SwWsClose::class, 'message'=> \app\listener\SwWsMessage::class ],
怎么选择是保存在config\swoole.php还是app\event.php配置中呢？首先我们 我们确定一下我们这个项目中存在有几个实时通讯，
如果只是存在一个实时通讯 个人建议 保存在
config\swoole.php如果是存在多个实时通讯，就保存在
app\event.phpkey值 必须是
swoole.websocket.事件名称例如swoole.websocket.Message
开始写事件中中方法
连接事件app\listener\SwWsConnect.php
public function handle($event, \think\swoole\websocket $ws)
{
// 获取当前发送者的fd
$fd = $ws->getSender();
echo "server: handshake success with fd{$fd}\n";
}
关闭事件app\listener\SwWsClose.php
public function handle($event, \think\swoole\websocket $ws)
{
$fd = $ws->getSender();
echo "client {$fd} closed\n";
}
message事件app\listener\SwWsMessage.php
public function handle($event, \think\swoole\websocket $ws)
{
$fd = $ws->getSender();
$data = json_encode($event);
echo "receive from {$fd}:{$data}\n";
$ws->emit("this is server", $fd);
}
启动php think swoole进行测试
think-swoole中的websocket方法总结
//给自己发消息
$ws->emit("this is server", $ws->getSender());
//给指定一个fd发消息
$ws->to($to)->emit("messagecallback",$data);
//给指定多个人发消息
$ws->to([1,2,3])->emit("messagecallback",$data);
//发送给所有的(不包含自己)
$ws->broadcast()->emit("messagecallback",$data);
//模拟formfd 给tofd 发送消息
$ws->setSender($formfd)->to($tofd)->emit("messagecallback",$data);
注意：在多个实时通讯场景下使用emit第一个参数传入 传入 事件名称callback 例如
messagecallback
如果你发现你think-swoole中有些没有swoole中的方法可以这么干
$sw = app('swoole.server');
$sw = app("think\swoole\Manager")->getServer();
//以上二选一
$es = $sw->isEstablished($fd); //检查连接是否为有效的WebSocket客户端连接
var_dump($es);
聊天室room实现
前端文件参考 html\room.html 或 html\room-socket-io.html
php think make:listener SwRoomJoin php think make:listener SwRoomLeave php think make:listener SwRoomMessage
事件绑定
// 加入房间 'swoole.websocket.RoomJoin' => [ \app\listener\SwRoomJoin::class ], // 离开房间 'swoole.websocket.Roomleave' => [ \app\listener\SwRoomLeave::class ], // 在房间发消息 'swoole.websocket.RoomMessage' => [ \app\listener\SwRoomMessage::class ]
加入房间逻辑
public function handle($event, \think\swoole\websocket $ws, \think\swoole\websocket\room $room)
{
$fd = $ws->getSender();
//客户端假如定的room
$roomid = $event['room'];
//获取指定房间下有哪些客户端
$roomfds = $room->getClients($roomid);
// 判断这个房间有没有自己 如果有自己就不需要再次发送通知
if (in_array($fd, $roomfds)) {
$ws->to($roomfds)->emit("roomjoincallback", "房间{$roomid}已加入");
return;
}
//加入房间
$ws->join($roomid);
$ws->to($roomfds)->emit("roomjoincallback", "{$fd}加入房间{$roomid}成功");
}
离开房间逻辑
public function handle($event, \think\swoole\websocket $ws, \think\swoole\websocket\Room $room)
{
$roomid = $event['room'];
$fd = $ws->getSender();
$roomfds = $room->getClients($roomid);
if (!in_array($fd, $roomfds)) {
$ws->emit("roomleavecallback", "{$fd}不在{$roomid}房间内，怎么离开~");
return;
}
//离开房间
$ws->leave($roomid);
//获取当前客户端加入了哪些客户端
$rooms = $room->getRooms($fd);
$ws->to($roomfds)->emit("roomleavecallback", "{$fd}已离开了~~");
}
在房间发布聊天逻辑
public function handle($event, \think\swoole\websocket $ws, \think\swoole\websocket\room $room)
{
//
$roomid = $event['room'];
$text = $event['text'];
$fd = $ws->getSender();
$roomfds = $room->getClients($roomid);
if (!in_array($fd, $roomfds)) {
$ws->emit("roommessagecallback", "{$fd}不在{$roomid}房间内，无法进入发布聊天~");
return;
}
$ws->to($roomfds)->emit("roommessagecallback", $text);
}
事件订阅
php think make:listener SwSubscribe
applistenerSwSubscribe.php
46bbf8c9f7825572c4d90f0300492227ws = app('think\swoole\Websocket');
// }
public function __construct(\think\Container $c)
{
$this->ws = $c->make(\think\swoole\Websocket::class);
}
public function onConnect()
{
$fd = $this->ws->getSender();
echo "server: handshake success with fd{$fd}\n";
}
public function onClose()
{
$fd = $this->ws->getSender();
echo "client {$fd} closed\n";
}
public function onMessage($event)
{
$fd = $this->ws->getSender();
var_dump($event);
echo "server: handshake success with fd{$fd}\n";
$this->ws->emit("this is server", $fd);
}
}
有点类似 将原生的swoole代码改成面向对象代码，生效方法
config\swoole.php中在subscribe加入\app\listener\SwSubscribe::class'subscribe' => [ \app\listener\SwSubscribe::class ],在
app\event.php文件中的swoole.websocket.Connect相当于app\listener\SwSubscribe.php文件中的onConnect函数。如果同时存在的存在的话，就会向客户端发送2次以上的消息
Task任务投递
https://wiki.swoole.com/#/start/start_task
生成事件
php think make:listener SwSendEmailTask
编写发送邮件方法app\listener\SwSendEmailTask.php
public function handle($event)
{
var_dump($event);
//
echo "开发发送邮件".time();
sleep(3);
echo "结束发送邮件".time();
}
注册事件app\event.php
'swoole.task'=>[ \app\listener\SwSendEmailTask::class ],
在控制器中投递任务
public function doRegister()
{
$server = app('swoole.server');
$server->task(\app\listener\SwSendEmailTask::class);
return "注册成功";
}
public function doRegister(\think\swoole\Manager $manager)
{
$server = $manager->getServer();
$server->task(\app\listener\SwSendEmailTask::class);
return "注册成功";
}
public function doRegister(\Swoole\Server $server)
{
$server->task(\app\listener\SwSendEmailTask::class);
return "注册成功";
}
三种获取\Swoole\Server,任意选其一
在swoole中还有一个事件叫finish，它的作用就是把异步任务的结果返回，在think-swool是这么处理的
定义一个发送邮件异步任务处理结果的事件
php think make:listener SwSendEmailFinish
注册事件app\event.php
'swoole.finish'=>[ \app\listener\SwSendEmailFinish::class ],
在task任务中调用
public function handle($event)
{
var_dump($event);
//
echo "开发发送邮件".time();
sleep(3);
echo "结束发送邮件".time();
$event->finish(\app\listener\SwSendEmailFinish::class);
}
高性能共享内存 Table
https://wiki.swoole.com/#/mem...
先定结构在进行操作数据（原生swoole操作）
$table = new Swoole\Table(1024);
//创建表
$table->column("id", Swoole\Table::TYPE_INT);
$table->column("name", Swoole\Table::TYPE_STRING);
$table->column("money", Swoole\Table::TYPE_FLOAT);
$table->create();
//添加数据
$table->set("zq", [
'id' => 1,
'name' => "zhiqiang",
'money' => 100,
]);
//获取一行数据
$table->get("zq");
// 修改数据
// 字段递增
$table->incr("zq","money",2);
//递减
$table->decr("zq","money",2);
// 返回 table 中存在的条目数。
$table->count();
//遍历table中的数据
foreach($table as $item){
var_dump($item);
}
think-swoole中的操作
先对table表结构进行初始化config\swoole.php
'tables' => [ 'user'=>[ 'size'=>1024, 'columns'=>[ [ 'name'=>'id', 'type'=>\Swoole\Table::TYPE_INT ], [ 'name'=>'name', 'type'=>\Swoole\Table::TYPE_STRING, 'size'=>32 ], [ 'name'=>'money', 'type'=>\Swoole\Table::TYPE_FLOAT ], ], ], ],
操作数据
$table = app('swoole.table.user');
$table->set("zq", [
'id' => 1,
'name' => "zhiqiang",
'money' => 100
]);
//获取一行数据
$table->get("zq");
// 修改数据
// 字段递增
$table->incr("zq", "money", 2);
//递减
$table->decr("zq", "money", 2);
// 返回 table 中存在的条目数。
$table->count();
//遍历table中的数据
foreach ($table as $item) {
var_dump($item);
}
// 检查 table 中是否存在某一个 key。
$table->exist('zq');
//获取实际占用内存尺寸,单位字节
$table->momorySize();
RPC
RPC(Remote Procedure Call)：远程过程调用，它是一种通过网络从远程计算机程序上请求服务，而不需要了解底层网络技术的思想。
详细介绍：https://developer.51cto.com/a...
- 解决分布式系统中，服务之间的调用问题。
- 远程调用时，要能够像本地调用一样方便，让调用者感知不到远程调用的逻辑。
- 节点角色说明：
- Server: 暴露服务的服务提供方
- Client: 调用远程服务的服务消费方
- Registry: 服务注册与发现的注册中心
think-swoole实现RPC功能
服务器端
接口定义app/rpc/interfaces/UserInterface.php
3726315c3b3d0564a100f1ab9a1450d6 [ 'server' => [ //开启rpc服务 'enable' => true, //rpc端口 'port' => 9000, 'services' => [ //注册服务 \app\rpc\services\UserService::class ], ], // 如果填写也是可以调用其他服务端 'client' => [ ], ],
启动服务端
php think swoole start / php think swoole:rpc
客户端
'rpc' => [ 'server' => [ ], 'client' => [ 'tp6'=>[ //服务端的ip地址 'host'=>'127.0.0.1', //服务端对应的端口 'port'=>'9000' ] // 更多服务端 ], ],
运行php think rpc:interface生成RPC接口文件app\rpc.php
3bc2c1b4a3deab348d628488d9a683ad ['rpc\contract\tp6\UserInterface']];
在控制器调用
public function index(\rpc\contract\tp6\UserInterface $user)
{
//
$user->find(1);
// $user->create();
}
定时任务
在think-swoole 2.0版本的时候还是支持自定义定时任务配置,详细参考https://github.com/top-think/think-swoole/tree/2.0
在3.0就不支持了，在这里介绍一个通用的命令行启动定时任务
php think make:command SwooleTimer
加载命令行config/console.php
'commands' => [ 'swooletimer'=>app\command\SwooleTimer::class ........... ],
书写命令脚本app/command/SwooleTimer.php
2c7875dc6c653367e938e61ba5593bfdsetName('app\command\swooletimer')
->addArgument('action', Argument::OPTIONAL, "start | stop", 'start')
->setDescription('Swoole Timer for ThinkPHP');
}
public function handle()
{
$action = $this->input->getArgument('action');
if (in_array($action, ['start','stopall'])) {
$this->app->invokeMethod([$this, $action], [], true);
} else {
$this->output->writeln("bbbcc7d749ec7f3e0fb2ba5af34b74a7Invalid argument action:{$action}, Expected start4c8d80f29f204b22c4490983d39ebac7");
}
}
/**
* 启动定时任务 主要任务计划在这里书写
*/
protected function start()
{
// https://wiki.swoole.com/#/timer
$timer_id=swoole_timer_tick(2000,function (){
echo "2s循环执行需要做的事情".time()."\n";
});
$this->output->writeln("Swoole Timer_id:{$timer_id} ");
}
/**
* 清除所有的定时任务
*/
protected function stop(){
swoole_timer_clear_all();
$this->output->writeln("Swoole Timer clear all ok");
}
}
