rabbitmq消息队列php实际应用

rabbitmq 消息队列 php应用

前段时间公司需要用到消息队列，就凑时间研究了下rabbitmq，由于本人ubuntu环境，windows应用不确定哈。

代码贴出来了，根据自身项目编写，并不适合所有项目，需要调整自行改动。

1.MQ则是遵循了AMQP协议的具体实现和产品，所以需要AMQPLib的支持

composer require php-amqplib/php-amqplib

2.参考

rabbitmq官方示例

3.base示例

4.加入队列

use common\components\MqBase;

    /**     * 加入队列     * @param array $data         Description  队列数据        $data['time']不存在时只创建队列     * @param type $name          Description  队列名     * @param type $exchange_name Description  路由名     * @param type $queue_durable Description  队列是否持久化     * @param int $message_durableDescription  消息是否持久化     * @param type $config        Description  队列配置     * @throws Exception     */    public function send(array $data, $name, $exchange_name, $type = 'fanout', $queue_durable = true, $message_durable = true, $config = array()) {        $mqBase = new MqBase($config);        $mqBase->open();        $mqBase->exchangeDeclare($exchange_name, $type, $queue_durable);        $mqBase->queueDeclare($name, false, $queue_durable, false, false);        $mqBase->basicPublish($data, $message_durable, $name);    }

5.处理示例

    /**     * 处理队列     * 可根据项目自行调整     * @param type $name 队列名     */    public function actionIndex($name, $exchange_name) {        $mqBase = new MqBase();        $mqBase->open();        $mqBase->queueDeclare($name, false, true, false, false);        if($exchange_name == '') {            $exchange_name = $name;        }        $mqBase->queueBind($name, $exchange_name);        $callback = function($msg) {            $data = unserialize($msg->body);            $func = $data['func'];            $class = $data['class'];            if(isset($data['time']) && $data['time'] <= time()) {                if(is_object($data['class'])) {                    $log = $class->$func($data['paramer']);                } else {                    $log = $class::$func($data['paramer']);                }                if($log === true) {                    $msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);                }            }        };        $mqBase->receive($name, $callback);        $mqBase->wait();    }}
