前言
ThinkPHP即将迎来最新版本6.0,针对目前越来越流行Swoole,thinkphp也推出了最新的扩展think-swoole 3.0。
介绍
即将推出的tp6.0,已经适配swoole.并推出think-swoole 3.0,并且默认适配了socketio。和2.0版本在使用方法上面有些许不同。
Websocket 继承与Http,进行websocket连接之前需要一次HTTP请求,如果当期地址支持websocket则返回101,然后进行连接。也就是说并不是我的服务支持websocket后,请求每个连接地址都可以进行websocket连接,而是需要预先适配才可以连接。

handler和parser大大方便了自定义websocket服务,默认系统集成socketio。
本文主要介绍如何使用socketio,这里假设大家有socketio有一定了解和使用基础。
socketIo默认会在请求地址后加相应的参数
同时,socketio默认情况下,会认为 http://url/socket.io/ 是支持websocket服务的地址。
而在tp-swoole3.0内部已经对该地址请求进行了处理

TP6.0,插件注册采用了service方式进行了注册,可在tp-swoole 服务注册文件中查看路由注册信息,如果想自定义链接规则,则可以覆盖该路由。

Websocket路由配置方法
在app目录下新建websocket.php文件,其中需要注意,由于使用了反射,闭包参数名称不能随意定义,不然无法注入。第一个参数是websocket,是当前websocket的Server对象,第二个参数data是客户端发送的数据。其中socketio emit的第一个参数和Websocket::on的第一个参数一致,作为事件名称。

$websocket ->emit( "test" , "asd" );
});
Websocket::on( "test1" , function ( $websocket , $data ) {
$websocket ->emit( "test" , "asd" );
});
Websocket::on( "join" , function ( hinkswooleWebsocket $websocket , $data ) {
$websocket ->join( "1" );
});

参考如上方法即可使用全新的websocket服务。当然tp-swoole3.0同样还有许多其他的新功能,这些功能需要大家去摸索尝试。
我也会在接下来的文章中,一起与大家分享我的使用过程。
