利用qt使用hpsocket

HP-Socket是一个基于IOCP的高性能TCP/UDP网络通信框架，可以在Windows平台下快速开发高性能的网络应用程序。下面是使用Qt调用HP-Socket实现TCP客户端的步骤：

1. 下载HP-Socket框架，解压后将include、lib、bin三个目录复制到Qt项目的根目录下。

2. 在Qt项目中添加以下代码实现TCP客户端的功能：

#include "stdafx.h"
#include "HPTypeDef.h"
#include "HPNetHelp.h"
#include "HPClient.h"
#include <QString>

// HP-Socket事件处理类
class CListenerImpl : public CTcpClientListener
{
public:
    CListenerImpl()
    {
        m_pClient = nullptr;
    }

    ~CListenerImpl()
    {
        if (m_pClient != nullptr)
        {
            m_pClient->Destroy();
            m_pClient = nullptr;
        }
    }

    EnHandleResult OnConnect(ITcpClient* pSender, CONNID dwConnID)
    {
        qDebug() << "OnConnect, Connection ID: " << dwConnID;
        return HR_OK;
    }

    EnHandleResult OnReceive(ITcpClient* pSender, CONNID dwConnID, const BYTE* pData, int iLength)
    {
        qDebug() << "OnReceive, Connection ID: " << dwConnID;
        QString strData = QString::fromLocal8Bit((char*)pData, iLength);
        qDebug() << "Received Data: " << strData;
        return HR_OK;
    }

    EnHandleResult OnClose(ITcpClient* pSender, CONNID dwConnID, EnSocketOperation enOperation, int iErrorCode)
    {
        qDebug() << "OnClose, Connection ID: " << dwConnID << ", Operation: " << enOperation << ", Error Code: " << iErrorCode;
        return HR_OK;
    }

    void SetClient(CHttpClient* pClient)
    {
        m_pClient = pClient;
    }

private:
    ITcpClient* m_pClient;
};

// TCP客户端类
class CTcpClient
{
public:
    CTcpClient()
    {
        m_pListener = new CListenerImpl();
        m_pClient = nullptr;
    }

    ~CTcpClient()
    {
        if (m_pClient != nullptr)
        {
            m_pClient->Destroy();
            m_pClient = nullptr;
        }

        if (m_pListener != nullptr)
        {
            delete m_pListener;
            m_pListener = nullptr;
        }
    }

    bool Connect(LPCTSTR lpszAddress, USHORT usPort)
    {
        if (m_pClient != nullptr)
        {
            m_pClient->Destroy();
            m_pClient = nullptr;
        }

        m_pClient = ::Create_HP_TcpClient(m_pListener);
        if (m_pClient == nullptr)
        {
            qDebug() << "Create_HP_TcpClient Failed!";
            return false;
        }

        m_pListener->SetClient(this);

        if (!::HP_Client_Start(m_pClient, lpszAddress, usPort))
        {
            qDebug() << "HP_Client_Start Failed!";
            return false;
        }

        return true;
    }

    bool Send(LPCTSTR lpszData, int iLength)
    {
        if (m_pClient == nullptr)
        {
            qDebug() << "TCP Client Not Initialized!";
            return false;
        }

        if (!::HP_Client_Send(m_pClient, (const BYTE*)lpszData, iLength))
        {
            qDebug() << "TCP Client Send Failed!";
            return false;
        }

        return true;
    }

private:
    CListenerImpl* m_pListener;
    ITcpClient* m_pClient;
};

int main(int argc, char* argv[])
{
    QCoreApplication a(argc, argv);

    CTcpClient tcpClient;
    if (!tcpClient.Connect(_T("127.0.0.1"), 5555))
    {
        qDebug() << "TCP Client Connect Failed!";
        return -1;
    }

    if (!tcpClient.Send(_T("Hello, HP-Socket!"), 18))
    {
        qDebug() << "TCP Client Send Failed!";
        return -1;
    }

    return a.exec();
}

以上代码实现了一个TCP客户端，当连接建立成功、接收到数据、连接关闭时，将会调用相应的事件处理函数。可以根据需要在事件处理函数中添加自己的处理逻辑。
