c++ - 无法使用 AMQP-CPP 在 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;
}

rabbitmqModels.h代码在哪里:

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;
    }
};

代码构建没有错误。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。

问题是我看不到任何消息进入我在服务器上定义的队列。我必须只使用 TCPHandler 吗？我找不到适用于 Windows 的 TCPHandler 的任何实现。你能提供任何帮助吗？提前致谢!

Answer 1

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

将您的代码更改为:

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

请注意 RabbitMQ documentation非常彻底。请花时间阅读它并完成其中一个特定于语言的教程。
