php-amqplib连接错误

Question

我只是在做一个测试，试图让RabbitMQ与php-amqplib一起工作。我刚刚编辑了这个问题，以便它使用正确的端口。对此有什么想法吗？

这是我的PHP文件..。

1 #!/usr/bin/env php
2 <?php
3
4 require __DIR__ . '/vendor/autoload.php';
5
6 $dotenv = new Dotenv\Dotenv(__DIR__);
7 $dotenv->load();
8
9 $sample_msg = "0% chance of rain!";
10
11 $amqpConnection = new \PhpAmqpLib\Connection\AMQPStreamConnection(
12     getenv('RABBITMQ_HOST'),
13     getenv('RABBITMQ_PORT'),
14     getenv('RABBITMQ_USER'),
15     getenv('RABBITMQ_PASSWORD'),
16     getenv('RABBITMQ_VHOST')
17 );
18
19 $amqpChannel = $amqpConnection->channel();
20 $amqpChannel->queue_declare(getenv('SFTP_RABBITMQ_QUEUE'), false, true, false, false);
21
22 $msg = new AMQPMessage($sample_msg);
23 $channel->basic_publish($msg, '', 'hello');
24
25 echo " [x] Sent $sample_msg\n";

这是我的.env..。

RABBITMQ_HOST=dev.website.co.uk
RABBITMQ_PORT=5672 // ammended
RABBITMQ_VHOST=/
RABBITMQ_LOGIN=xxxxxx
RABBITMQ_PASSWORD=xxxxxx

SFTP_RABBITMQ_QUEUE=my_test_queue

这是composer.json..。

{
    "name": "neil/sftp-user-create",
    "type": "project",
    "require": {
        "php-amqplib/php-amqplib": "^2.7",
        "vlucas/phpdotenv": "^2.4"
        },
    "license": "proprietary",
    "authors": [
        {
             "name": "Me",
             "email": "my@email-address.com"
                                                             }
     ]
}

这就是我遇到的错误..。

您的代码中有几个问题：

1. 在您的.env文件中，您声明了RABBITMQ_LOGIN，但在代码中使用的是RABBITMQ_USER，这使您在修复连接端口(如@iainn所述)之后出现了空登录和“坏管道”错误。
2. $channel->basic_publish您没有任何名为$channel的变量，应该是$amqpChannel
3. 在basic_publish中，您的最后一个参数应该是要发送消息的队列的名称，因此它应该与queue_declare中的getenv('SFTP_RABBITMQ_QUEUE')相同。

在您的代码中修复这个问题：

$amqpConnection = new \PhpAmqpLib\Connection\AMQPStreamConnection(
     getenv('RABBITMQ_HOST'),
     getenv('RABBITMQ_PORT'),
     getenv('RABBITMQ_LOGIN'), // Use _LOGIN as declared in .env
     getenv('RABBITMQ_PASSWORD'),
     getenv('RABBITMQ_VHOST')
);

(...)

// Use $amqpChannel as you declared it earlier in code
// And use the same queue name in last parameter as you used in queue_declare
$amqpChannel->basic_publish($msg, '', getenv('SFTP_RABBITMQ_QUEUE'));
