我试图让RabbitMQ使用Yii控制台来发送交易电子邮件,但是我遇到了让PHP-AMQPLib库在Yii中工作的问题。我的代码如下:
<?php
class RabbitMqCommand extends CConsoleCommand {
public function actionSendMail() {
require_once ('/htdocs/code/wwwroot/protected/components/php-amqplib/amqp.inc');
$conn = new AMQPConnection ( 'localhost', 5672, 'guest', '123456', '/' );
$ch = $conn->channel ();
$ch->queue_declare ( 'msgs', false, true, false, false );
$ch->exchange_declare ( 'router', 'direct', false, true, false );
$ch->queue_bind ( 'msgs', 'router');
$ch->basic_consume ( 'msgs', 'consumer', false, false, false, false, 'processMessage' );
// Loop as long as the channel has callbacks registered
while ( count ( $ch->callbacks ) ) {
$ch->wait ();
}
$ch->close();
$conn->close();
}
public function processMessage($msg)
{
//process and send email
}
当我尝试从命令行执行此代码时,如下所示:
php -q /htdocs/code/wwwroot/protected/yiic RabbitMQ SendMail
我收到以下错误消息:
PHP Error[2]: call_user_func() expects parameter 1 to be a valid callback, function 'processMessage' not found or invalid function name

#12 /htdocs/code/wwwroot/protected/yiic(4): require_once()
知道我可能做错了吗?
答案 0 :(得分:3)
发生此错误是因为processMessage
是对象的实例方法,但basic_consume
的参数应该是全局PHP方法。
请参阅此主题以获取解决方案:PHP Call a instance method with call_user_func within the same class

请更改此行:
$ch->basic_consume ( 'msgs', 'consumer', false, false, false, false, 'processMessage' );
对此:
$channel->basic_consume('msgs', 'consumer', false, false, false, false, [new RabbitMqCommand,'process_message']);
