如何捕获失败的消息发布（RabbitMQ）？

Question

在basic_publish() 方法上捕获错误的最佳方法是什么？

<?php
require_once __DIR__ . '/vendor/.   autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();
$channel->queue_declare('hello', false, false, false, false);
$msg = new AMQPMessage('Hello World!');
$channel->basic_publish($msg, '', 'hello');
echo " [x] Sent 'Hello World!'\n";
$channel->close();
$connection->close();
?>

Answer 1

你可以简单地使用 try-catch 方法

... 尝试 { $channel->basic_publish($msg, '', '你好'); } 捕捉（错误 $e）{ // 做点什么 }
