服務啟動
當你在命令列php think swoole下執行完成之後就會啟動一個HTTP Server，可以直接存取目前的應用程式【建議教學：thinkphp
| swoole伺服器運行過程中php檔案是常駐記憶體運行，這樣就可以避免重複的讀取磁碟，重複的解釋編譯php，以便達到最高的效能，所以修改程式碼需要重啟服務 | think-swoole擴充功能提供熱更新功能，在偵測相關檔案有更新會自動重啟，不在需要手動完成重啟，方便開發調試 |
|---|---|
| 裡面設定 | APP_DEBUG = true會預設開啟熱更新 |
| #參數 | |
| 是否開啟熱更新 |
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";
});
$server->start();登入後複製
开启think-swoole的websocket功能 \config\swoole.php
'websocket' => [
'enable' => true,
],登入後複製
创建三个事件
php think make:listener SwWsConnect php think make:listener SwWsClose php think make:listener SwWsMessage
登入後複製
然后将这三个事件写到到事件监听中，分别有以下2中文件可以修改方式，注意二选一
thinkphp6自带的事件绑定app\event.php
'listen' => [
........
// 监听链接
'swoole.websocket.Connect' => [
\app\listener\SwWsConnect::class
],
//关闭连接
'swoole.websocket.Close' => [
\app\listener\SwWsClose::class
],
//发送消息场景
'swoole.websocket.Message' => [
\app\listener\SwWsMessage::class
]
],登入後複製
think-swoole事件绑定config\swoole.php
'listen' => [
'connect'=>\app\listener\SwWsConnect::class,
'close'=>\app\listener\SwWsClose::class,
'message'=> \app\listener\SwWsMessage::class
],登入後複製
怎么选择是保存在config\swoole.php还是app\event.php配置中呢？首先我们 我们确定一下我们这个项目中存在有几个实时通讯，
如果只是存在一个实时通讯 个人建议 保存在
config\swoole.php如果是存在多个实时通讯，就保存在
app\event.phpkey值 必须是
swoole.websocket.事件名称例如swoole.websocket.Message
开始写事件中中方法
连接事件app\listener\SwWsConnect.php
public function handle($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";
}登入後複製
关闭事件app\listener\SwWsClose.php
public function handle($event, \think\swoole\websocket $ws)
{
$fd = $ws->getSender();
echo "client {$fd} closed\n";
}登入後複製
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);
}登入後複製
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);登入後複製
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($es);登入後複製
聊天室room实现
前端文件参考 html\room.html 或 html\room-socket-io.html
php think make:listener SwRoomJoin php think make:listener SwRoomLeave php think make:listener SwRoomMessage
登入後複製
事件绑定
// 加入房间
'swoole.websocket.RoomJoin' => [
\app\listener\SwRoomJoin::class
],
// 离开房间
'swoole.websocket.Roomleave' => [
\app\listener\SwRoomLeave::class
],
// 在房间发消息
'swoole.websocket.RoomMessage' => [
\app\listener\SwRoomMessage::class
]登入後複製
加入房间逻辑
public function handle($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");
}登入後複製
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", "{$fd}已离开了~~");
}登入後複製
在房间发布聊天逻辑
public function handle($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);
}登入後複製
事件订阅
php think make:listener SwSubscribe
登入後複製
applistenerSwSubscribe.php
<?php
declare (strict_types = 1);
namespace app\listener;
class SwSubscribe
{
protected $ws = null;
// public function __construct()
// {
// $this->ws = 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", $fd);
}
}登入後複製
有点类似 将原生的swoole代码改成面向对象代码，生效方法
config\swoole.php中在subscribe加入\app\listener\SwSubscribe::class'subscribe' => [ \app\listener\SwSubscribe::class ],登入後複製在
app\event.php文件中的swoole.websocket.Connect相当于app\listener\SwSubscribe.php文件中的onConnect函数。如果同时存在的存在的话，就会向客户端发送2次以上的消息
Task任务投递
https://wiki.swoole.com/#/start/start_task
生成事件
php think make:listener SwSendEmailTask
登入後複製
编写发送邮件方法app\listener\SwSendEmailTask.php
public function handle($event)
{
var_dump($event);
//
echo "开发发送邮件".time();
sleep(3);
echo "结束发送邮件".time();
}登入後複製
注册事件app\event.php
'swoole.task'=>[
\app\listener\SwSendEmailTask::class
],登入後複製
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)
{
$server->task(\app\listener\SwSendEmailTask::class);
return "注册成功";
}登入後複製
三种获取\Swoole\Server,任意选其一在swoole中还有一个事件叫finish，它的作用就是把异步任务的结果返回，在think-swool是这么处理的
定义一个发送邮件异步任务处理结果的事件
php think make:listener SwSendEmailFinish
登入後複製
注册事件app\event.php
'swoole.finish'=>[
\app\listener\SwSendEmailFinish::class
],登入後複製
在task任务中调用
public function handle($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);
}登入後複製
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);
}登入後複製
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
],
],
],
],登入後複製
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();登入後複製
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
<?php
namespace app\rpc\interfaces;
interface UserInterface

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
登入後複製
加载命令行config/console.php
'commands' => [
'swooletimer'=>app\command\SwooleTimer::class
