swoole_process父子进程管道通信的代码示例

本篇文章给大家带来的内容是关于swoole_process父子进程管道通信的代码示例，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。

话不多说直接上代码

创建的子进程：

public function __construct()    {        $this->redis   = Container::get(SwooleRedis::class);//获取异步redis获取更高性能        $this->process = new swoole_process(function (swoole_process $process) {            return $this->process($process);        }, false, SOCK_DGRAM);        $this->process->name('Test_Gateway');        $this->process->useQueue();        $this->process->start();//启动子进程    }        /**     * 子进程处理逻辑     * @param swoole_process $process     */    private function process(swoole_process $process)    {        $client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC); //异步非阻塞                $client->on("connect", function (swoole_client $cli) use ($process) {            $process->write('connected');        });                $client->on("receive", function (swoole_client $cli, $data) use ($process) {            $process->write($data);        });                $client->on("error", function (swoole_client $cli) use ($process) {            $process->write('error');        });                $client->on(&q<span style="color:transparent">~来1源gaodai#ma#com搞*代#码1网</span><abbr>搞代gaodaima码</abbr>uot;close", function (swoole_client $cli) use ($process) {            $process->write('close');        });                if ($client->connect('127.0.0.1', 90, -1)) {                } else {            $process->write('网关连接失败');        }                swoole_event_add($process->pipe,            function ($pipe) use ($process, $client) {//读取父进程管道消息                $client->send($process->read());            });    }

父进程onWorkerStart:

/**     * @param swoole_server $serv     * @param               $worker_id     */    public function onWorkerStart(\swoole_server $serv, $worker_id)    {        if ($worker_id === 0) {            swoole_timer_tick(1000, function () {                $this->process->write('ping');            });            $process = $this->process;            swoole_event_add($process->pipe,                function ($pipe) use ($process) {//获取子进程的管道消息                    echo "子进程消息：" . $process->read() . PHP_EOL;                });        }    }

• 子进程的client客户端可以忽略不计，本demo只是掩饰管道通信的例子
• 使用管道就不可以使用消息队列：$process_push()和$process->pop();
• 理论上在父子进程各注册一个event_loop即可实现一边发消息一边接收
• 其他的后续补充
