当尝试使用AMQP 0-9-1与WSO2 MB通信时,我收到来自WSO2 MB的Andes核心的“权限被拒绝”AMQSecurityException。发生这种情况是因为我尝试使用路由键将队列绑定到主题。任何人都可以提供有关如何将AMQP 0-9-1库与WSO2 MB一起使用的指导吗?
具体来说,我的代码尝试使用路由密钥'rkey'发布到交换'texch',并通过运行时创建的队列使用路由密钥'rkey'绑定到'texch'来消息。
WSO2 MB的输出是:
[2013-04-02 14:27:34,012] INFO {org.wso2.andes.server.protocol.AMQProtocolEngine} - Closing channel due to: org.wso2.andes.AMQSecurityException: Permission denied: binding rkey [error code 403: access refused]

在WSO2 Message Broker中,不会为给定的任何名称动态创建交换。因此,如果主题需要使用“amq.topic”,则预定义的默认主题交换名称为WSO2 MB作为交换名称,如果是队列,则默认交换需要为'amq.direct'以避免此权限问题。
此外,如果需要创建新主题/直接交换(在您的情况下为'texch'),则需要在qpid-virtualhosts.xml文件中预先声明,然后您可以绑定队列/主题进入新的交流。有关此问题的更多指南,请参阅this博文。

我们必须如下配置quid-virtualhost.xml文件,以便在服务器启动时创建Q.
<!-- Here you can add remove exchange to this virtualhost-->
<exchange>
<type>direct</type>
<name>carbon.direct</name>
<durable>true</durable>
</exchange>
<exchange>
<type>topic</type>
<name>carbon.topic</name>
</exchange>
</exchanges>
<queues>
<queue>
<name>TEST</name>
<TEST>
<exchange>carbon.direct</exchange>
<durable>true</durable>
</TEST>
</queue>
我使用“amqp-ts”发送和接收来自javascripts的消息。
var amqp = require("amqp-ts");
var connection = new amqp.Connection("amqp://admin:admin@localhost:5672");
//var exchange = connection.declareExchange("carbon.direct",{noCreate: true});
var queue = connection.declareQueue("TEST",{noCreate: true});
//queue.bind(exchange);
queue.activateConsumer((message) => {
console.log("Message received: " + message.getContent());
});
// it is possible that the following message is not received because
// it can be sent before the queue, binding or consumer exist
var msg = new amqp.Message("Test");
queue.send(msg);
connection.completeConfiguration().then(() => {
// the following message will be received because
// everything you defined earlier for this connection now exists
var msg2 = new amqp.Message("Test2");
queue.send(msg2);
});
