我最近兩天瘋了,我無法建立與持久交換和持久隊列的NodeJS客戶端連接。NodeJS AMQP客戶端無法連接
所以PHP代碼創建併發送消息:
<?php
$connection = new AMQPConnection(array(
'host' => 'localhost',
'vhost' => 'bvh',
'port' => 5672,
'login' => 'bizneus',
'password' => 'lozinkus'
));
//$connection = new AMQPConnection();
$connection->connect();
if (!$connection->isConnected()) {
die('Not connected :(' . PHP_EOL);
}
// Open Channel
$channel = new AMQPChannel($connection);
// Declare exchange
$exchange = new AMQPExchange($channel);
$exchange->setName('biznea_e_1');
$exchange->setType('fanout');
$exchange->setFlags(AMQP_DURABLE);
$exchange->declare();
// Create Queue
$queue = new AMQPQueue($channel);
$queue->setName('notify');
$queue->setFlags(AMQP_DURABLE);
$queue->declare();
$message = $exchange->publish(json_encode($s), 'kljuc');
if (!$message) {
echo 'Message not sent', PHP_EOL;
} else {
echo 'Message sent!', PHP_EOL;
}
if ($connection->isConnected()) {
$connection->disconnect();
}
在屏幕上它說,messege發送。
接下來的事情是客戶端的NodeJS,它應該得到的消息,但它不能:
var amqp = require('amqp');
var conParam = {
host: 'localhost',
port: 5672,
login: 'bizneus',
password: 'lozinkus',
vhost: 'bvh'
}
var connection = amqp.createConnection(conParam);
connection.on('ready', function(){
var exchange = connection.exchange('biznea_e_1');
var queue = connection.queue('notify');
queue.bind('biznea_e_1', 'kljuc');
queue.subscribe({ack:true}, function(message){
var dj = JSON.parse(message.data.toString());
console.log(JSON.stringify(dj));
queue.shift();
});
});
,但我得到這個錯誤
events.js:66
throw arguments[1]; // Unhandled 'error' event
^
Error: PRECONDITION_FAILED - cannot redeclare exchange 'biznea_e_1' in vhost 'bvh' with different type, durable, internal or autodelete value

at Connection.<anonymous> (/home/zijad/node_modules/amqp/amqp.js:837:12)
我試圖刪除VAR交換= connection.exchange ( 'biznea_e_1');該行,但不能聲明隊列。
我只想發送消息從PHP到NodeJS deamon,這就是全部!
幫助:)
我退出使用這種方法,並開始使用Redis而不是AMQP,它在幾分鐘內更容易安裝和運行。 – theZiki
