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("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
