PHP基于rabbitmq操作类的生产者和消费者功能示例

php  /  管理员 发布于 7年前   294

本文实例讲述了PHP基于rabbitmq操作类的生产者和消费者功能。分享给大家供大家参考，具体如下：

注意事项：

1、accept.php消费者代码需要在命令行执行

2、'username'=>'asdf','password'=>'123456' 改成自己的帐号和密码

RabbitMQCommand.php操作类代码

$host,'port'=>5672,'username'=>$username,'password'=>$password,'vhost'=>'/')   */  public function __construct($configs = array(), $exchange_name = '', $queue_name = '', $route_key = '') {    $this->setConfigs($configs);    $this->exchange_name = $exchange_name;    $this->queue_name = $queue_name;    $this->route_key = $route_key;  }  private function setConfigs($configs) {    if (!is_array($configs)) {      throw new Exception('configs is not array');    }    if (!($configs['host'] && $configs['port'] && $configs['username'] && $configs['password'])) {      throw new Exception('configs is empty');    }    if (empty($configs['vhost'])) {      $configs['vhost'] = '/';    }    $configs['login'] = $configs['username'];    unset($configs['username']);    $this->configs = $configs;  }  /*   * 设置是否持久化，默认为True   */  public function setDurable($durable) {    $this->durable = $durable;  }  /*   * 设置是否自动删除   */  public function setAutoDelete($autodelete) {    $this->autodelete = $autodelete;  }  /*   * 设置是否镜像   */  public function setMirror($mirror) {    $this->mirror = $mirror;  }  /*   * 打开amqp连接   */  private function open() {    if (!$this->_conn) {      try {        $this->_conn = new AMQPConnection($this->configs);        $this->_conn->connect();        $this->initConnection();      } catch (AMQPConnectionException $ex) {        throw new Exception('cannot connection rabbitmq',500);      }    }  }  /*   * rabbitmq连接不变   * 重置交换机，队列，路由等配置   */  public function reset($exchange_name, $queue_name, $route_key) {    $this->exchange_name = $exchange_name;    $this->queue_name = $queue_name;    $this->route_key = $route_key;    $this->initConnection();  }  /*   * 初始化rabbit连接的相关配置   */  private function initConnection() {    if (empty($this->exchange_name) || empty($this->queue_name) || empty($this->route_key)) {      throw new Exception('rabbitmq exchange_name or queue_name or route_key is empty',500);    }    $this->_channel = new AMQPChannel($this->_conn);    $this->_exchange = new AMQPExchange($this->_channel);    $this->_exchange->setName($this->exchange_name);    $this->_exchange->setType(AMQP_EX_TYPE_DIRECT);    if ($this->durable)      $this->_exchange->setFlags(AMQP_DURABLE);    if ($this->autodelete)      $this->_exchange->setFlags(AMQP_AUTODELETE);    $this->_exchange->declare();    $this->_queue = new AMQPQueue($this->_channel);    $this->_queue->setName($this->queue_name);    if ($this->durable)      $this->_queue->setFlags(AMQP_DURABLE);    if ($this->autodelete)      $this->_queue->setFlags(AMQP_AUTODELETE);    if ($this->mirror)      $this->_queue->setArgument('x-ha-policy', 'all');    $this->_queue->declare();    $this->_queue->bind($this->exchange_name, $this->route_key);  }  public function close() {    if ($this->_conn) {      $this->_conn->disconnect();    }  }  public function __sleep() {    $this->close();    return array_keys(get_object_vars($this));  }  public function __destruct() {    $this->close();  }  /*   * 生产者发送消息   */  public function send($msg) {    $this->open();    if(is_array($msg)){      $msg = json_encode($msg);    }else{      $msg = trim(strval($msg));    }    return $this->_exchange->publish($msg, $this->route_key);  }  /*   * 消费者   * $fun_name = array($classobj,$function) or function name string   * $autoack 是否自动应答   *   * function processMessage($envelope, $queue) {      $msg = $envelope->getBody();      echo $msg."\n"; //处理消息      $queue->ack($envelope->getDeliveryTag());//手动应答    }   */  public function run($fun_name, $autoack = True){    $this->open();    if (!$fun_name || !$this->_queue) return False;    while(True){      if ($autoack) $this->_queue->consume($fun_name, AMQP_AUTOACK);      else $this->_queue->consume($fun_name);    }  }}

send.php生产者代码

accept.php消费者代码
