Question

我正在使用RabbitMQ 2.8.7 DotNet Client和WSO2 MB 3.2.1。我的部署环境是Win7 R1 64位或Win Server 08 R2 64位。我遇到了与Exchange的多个连接的问题，因此流式传输到多个消费者的数据会在间歇性时间丢失。我们已尝试将WSO2 MB更新为3.2.3＆amp;将我们的交换更改为扇出来解决这种连接丢失问题，但遇到了问题。

这个链接有点相关会“显得”：

http://wso2-oxygen-tank.10903.n7.nabble.com/Qpid-Authorization-handler-does-not-allow-to-subscribe-td2080.html

我首先想知道这是否是正确的方法。

其次，我想通过使用扇出来了解我们在运行时收到的当前错误，因为我们无法访问数据。以下是收到的错误，WSO2 MB日志输出＆amp;来自制作人的代码片段。

如果需要更多信息，请告知。

收到错误...

我发现在尝试连接Java时也会出现此问题。生产者的C＃代码的简短示例如下：

class Send {

    public static void Main() {

        string serverAddress = "amqp://" + "192.168.1.12" + ":5672/carbon"; 

            ConnectionFactory factory = new ConnectionFactory();

            factory.Uri = serverAddress;

            using (IConnection connection = factory.CreateConnection())

            using (IModel channel = connection.CreateModel()) {

            channel.QueueDeclare("fanout", false, false, false, null);

            channel.QueueBind("fanout", "fanout", "");

            string message = "Hello World!";

            byte[] body = System.Text.Encoding.UTF8.GetBytes(message);

            channel.BasicPublish("", "hello", null, body);
            Console.WriteLine(" [x] Sent {0}", message);
        }
    }
}

在WSO2 MB中，不会为给定的任何名称动态创建交换。因此，要使用'扇出'交换进行此操作，需要在qpid-virtualhosts.xml文件中预先声明。否则使用WSO2 MB的默认交换。

您似乎没有正确声明队列需要绑定的交换名称。如果它是队列，默认的交换名称声明就像，

 ch.ExchangeDeclare("amq.direct", "direct");

如果是主题，那么

 ch.ExchangeDeclare("amq.topic", "topic");

请参阅this博文，了解如何使用带有WSO2 Message Broker的.Net / C＃Consumer / Publisher客户端示例。

使用RabbitMQ C＃和AMQ / QPID＆amp; WSO2 Message Broker扇出交换
