用PHP尝试RabbitMQ(amqp扩展)实现消息的发送和接收

消费者:接收消息

逻辑:
创建连接-->创建channel-->创建交换机-->创建队列-->绑定交换机/队列/路由键-->接收消息

<?php /************************************** PHP amqp(RabbitMQ) Demo - consumer* Author: Linvo* Date: 2012/7/30*************************************///配置信息$conn_args = array(    'host' => '192.168.1.93',    'port' => '5672',    'login' => 'guest',    'password' => 'guest',    'vhost'=>'/');$e_name = 'e_linvo'; //交换机名$q_name = 'q_linvo'; //队列名$k_route = 'key_1'; //路由key//创建连接和channel$conn = new AMQPConnection($conn_args);if (!$conn->connect()) {    die("Cannot connect to the broker!\n");}$channel = new AMQPChannel($conn);//创建交换机$ex = new AMQPExchange($channel);$ex->setName($e_name);$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型$ex->setFlags(AMQP_DURABLE); //持久化echo "Exchange Status:".$ex->declare()."\n";//创建队列$q = new AMQPQueue($channel);$q->setName($q_name);$q->setFlags(AMQP_DURABLE); //持久化echo "Message Total:".$q->declare()."\n";//绑定交换机与队列,并指定路由键echo 'Queue Bind: '.$q->bind($e_name, $k_route)."\n";//阻塞模式接收消息echo "Message:\n";while(True){    $q->consume('processMessage');    //$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答}$conn->disconnect();/*** 消费回调函数* 处理消息*/function processMessage($envelope, $queue) {    $msg = $envelope->getBody();    echo $msg."\n"; //处理消息    $queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答}

生产者:发送消息

逻辑:
创建连接-->创建channel-->创建交换机对象-->发送消息

<?php /************************************** PHP amqp(RabbitMQ) Demo - publisher* Author: Linvo* Date: 2012/7/30*************************************///配置信息$conn_args = array(    'host' => '192.168.1.93',    'port' => '5672',    'login' => 'guest',    'password' => 'guest',    'vhost'=>'/');$e_name = 'e_linvo'; //交换机名//$q_name = 'q_linvo'; //无需队列名$k_route = 'key_1'; //路由key//创建连接和channel$conn = new AMQPConnection($conn_args);if (!$conn->connect()) {    die("Cannot connect to the broker!\n");}$channel = new AMQPChannel($conn);//消息内容$message = "TEST MESSAGE! 测试消息!";//创建交换机对象$ex = new AMQPExchange($channel);$ex->setName($e_name);//发送消息//$channel->startTransaction(); //开始事务for($i=0; $ipublish($message, $k_route)."\n";}//$channel->commitTransaction(); //提交事务$conn->disconnect();

需要注意的地方是:

queue对象有两个方法可用于取消息:consume和get。
前者是阻塞的,无消息时会被挂起,适合循环中使用;

后者则是非阻塞的,取消息时有则取,无则返回false。

测试截图

运行消费者:

1343873405_2469

运行生产者,发消息:

1343873408_3083

消费者接收到消息:

1343873412_6992

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

SecLists

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
