无法在带有AMQP-CPP的RabbitMQ服务器上成功发布消息

Question

我正在尝试在Windows上制作一个简单的控制台应用程序。我已经安装了AMQP-CPP并将该库包含在我的Visual Studio项目中。我的任务是创建与Rabbitmq服务器的简单通信。

主要功能是：

#include <amqpcpp.h>
#include "rabbitmqModels.h"

int main(){

    string msg = "hello world";
    string queueName = "message_queue";
    string exchangeName = "myexchange";
    string routingKey = "hello";

    Address address("amqp://guest:guest@localhost:15672");
    MyConnectionHandler myHandler;
    Connection connection(&myHandler, address);
    Channel channel(&connection);

    channel.declareQueue(queueName);
    channel.declareExchange(exchangeName, direct).onSuccess([]();
    channel.bindQueue(exchangeName, queueName, routingKey);
    channel.publish(exchangeName, routingKey, msg, msg.size());

    return 0;
}

其中rabbitmqModels.h代码为：

using namespace AMQP;
class MyConnectionHandler : public ConnectionHandler
{
private:
    /**
     *  Method that is called by the AMQP library every time it has data
     *  available that should be sent to RabbitMQ.
     *  @param  connection  pointer to the main connection object
     *  @param  data        memory buffer with the data that should be sent to RabbitMQ
     *  @param  size        size of the buffer
     */
    virtual void onData(Connection* connection, const char* data, size_t size)
    {
        // @todo
        //  Add your own implementation, for example by doing a call to the
        //  send() system call. But be aware that the send() call may not
        //  send all data at once, so you also need to take care of buffering
        //  the bytes that could not immediately be sent, and try to send
        //  them again when the socket becomes writable again
    }

    virtual void onReady(Connection* connection) override
    {
        // @todo
        //  add your own implementation, for example by creating a channel
        //  instance, and start publishing or consuming
        std::cout << "Connection is established...\n";

    }

    virtual void onError(Connection* connection, const char* message)
    {
        // report error
        std::cout << "Connection Error: " << message << std::endl;
    }

    virtual void onClosed(Connection* connection)
    {
        std::cout << "closed" << std::endl;

    }

    virtual void onConnected(Connection* connection)
    {
        std::cout << "connected" << std::endl;
    }
};

该代码的构建没有错误。请注意，我的Rabbitmq服务器在localhost：15672上运行，并且我已经定义了队列和交换/路由键。

事实是，我看不到任何消息进入服务器上已定义的队列。我只需要使用TCPHandler吗？我找不到Windows的TCPHandler的任何实现。您能提供什么帮助吗？预先感谢！

Answer 1

端口15672是管理Web界面和REST API的默认HTTP端口。您要使用AMQP端口，即5672。

将您的代码更改为此：

Address address("amqp://guest:guest@localhost:5672");

请注意，RabbitMQ documentation非常详尽。请花点时间阅读它，并完成其中一种特定于语言的教程。
