Windwos环境下用QT开发 CTP下单软件

新建工程

选择编译方式，windwos下要选用MSVC的编辑方式

添加接口的库文件

我的库文件放在了根目录下面的 TradeApi\win32下面

添中库文件完成后 .pro 中会自动生成如下代码

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/TradeApi/win32/ -lthostmduserapi_se
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/TradeApi/win32/ -lthostmduserapi_sed
else:unix: LIBS += -L$$PWD/TradeApi/win32/ -lthostmduserapi_se

INCLUDEPATH += $$PWD/TradeApi/win32
DEPENDPATH += $$PWD/TradeApi/win32

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/TradeApi/win32/ -lthosttraderapi_se
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/TradeApi/win32/ -lthosttraderapi_sed
else:unix: LIBS += -L$$PWD/TradeApi/win32/ -lthosttraderapi_se

INCLUDEPATH += $$PWD/TradeApi/win32
DEPENDPATH += $$PWD/TradeApi/win32

主窗体需要实现CTP的API接口类

class MainWindow : public QMainWindow, public CThostFtdcTraderSpi, public CThostFtdcMdSpi
{
    Q_OBJECT

private:
    CThostFtdcTraderApi* m_ptraderapi;
    TThostFtdcBrokerIDType	m_BrokerID;
    TThostFtdcUserIDType	m_UserID;
    TThostFtdcInvestorIDType m_InvestorID;
    TThostFtdcPasswordType	m_Password;
    TThostFtdcAuthCodeType	m_AuthCode;
    TThostFtdcAppIDType	m_AppID;

    void InitCTP();

    int UserLogin();
    int Authenticate();


    // 重写CThostFtdcTraderSpi方法
    void OnFrontConnected();
    void OnFrontDisconnected(int nReason);
    void OnRspAuthenticate(CThostFtdcRspAuthenticateField *pRspAuthenticateField, CThostFtdcRspInfoField *pRspInfo, int nRequestID, bool bIsLast);
    void OnRspUserLogin(CThostFtdcRspUserLoginField * pRspUserLogin, CThostFtdcRspInfoField * pRspInfo, int nRequestID, bool bIsLast);
    void OnRspSettlementInfoConfirm(CThostFtdcSettlementInfoConfirmField * pSettlementInfoConfirm, CThostFtdcRspInfoField * pRspInfo, int nRequestID, bool bIsLast);
    void OnRspQryInstrument(CThostFtdcInstrumentField * pInstrument, CThostFtdcRspInfoField * pRspInfo, int nRequestID, bool bIsLast);
    void OnRspOrderInsert(CThostFtdcInputOrderField * pInputOrder, CThostFtdcRspInfoField * pRspInfo, int nRequestID, bool bIsLast);
    void OnRtnOrder(CThostFtdcOrderField * pOrder);
    void OnRtnTrade(CThostFtdcTradeField * pTrade);
    void OnRspError(CThostFtdcRspInfoField * pRspInfo, int nRequestID, bool bIsLast);
    void OnRspQrySettlementInfo(CThostFtdcSettlementInfoField* pSettlementInfo, CThostFtdcRspInfoField* pRspInfo, int nRequestID, bool bIsLast);
    void OnRspQryInvestorPosition(CThostFtdcInvestorPositionField *pInvestorPosition, CThostFtdcRspInfoField *pRspInfo, int nRequestID, bool bIsLast);
    void OnErrRtnOrderAction(CThostFtdcOrderActionField *pOrderAction, CThostFtdcRspInfoField *pRspInfo);
    void OnRspOrderAction(CThostFtdcInputOrderActionField *pInputOrderAction, CThostFtdcRspInfoField *pRspInfo, int nRequestID, bool bIsLast);
    void OnErrRtnOrderInsert(CThostFtdcInputOrderField *pInputOrder, CThostFtdcRspInfoField *pRspInfo);
    void OnRspQryOrder(CThostFtdcOrderField *pOrder, CThostFtdcRspInfoField *pRspInfo, int nRequestID, bool bIsLast);
    void OnRspQryTradingAccount(CThostFtdcTradingAccountField *pTradingAccount, CThostFtdcRspInfoField *pRspInfo, int nRequestID, bool bIsLast);



    int ReqQryTradingAccount();
    int qryInstrument(QString sInstrumentID);
    int qryInvestorPositon();
    int QryOrder();
    int CancelOrder(CThostFtdcOrderField AOrder);
    void ReqSettlementInfoConfirm();


    void AppendLog(QString msg);

public:
    explicit MainWindow(QWidget *parent = nullptr);
    ~MainWindow();

private slots:
    void on_btn_login_clicked();

    void on_btn_qry_Order_clicked();

    void on_pushButton_clicked();

    void on_pushButton_2_clicked();

    void on_pushButton_3_clicked();

    void on_AppendMsg(QString msg);

signals:
    void send_AppendMsg(QString msg);

private:
    Ui::MainWindow *ui;
};

在目录下面flow文件夹一定要有。

开发中中遇到的问题：
1、CTP回调函数中直接操作UI控件会出现错误或控件刷新不及时如下图。

可以通过信号与槽的方式处理(请看代码中的实现)

例如：向textedit中添加,日志信息

private slots:
  void on_AppendMsg(QString msg);

signals:
    void send_AppendMsg(QString msg);

connect(this, SIGNAL(send_AppendMsg(QString)), this, SLOT(on_AppendMsg(QString)));



void MainWindow::OnFrontConnected(){
    qDebug("OnFrontConnected");
    emit send_AppendMsg("OnFrontConnected");
}

void MainWindow::on_AppendMsg(QString msg){
QDateTime current_date_time = QDateTime::currentDateTime();
QString current_date = current_date_time.toString("yyyy.MM.dd hh:mm:ss.zzz");
ui->edt_log->append(current_date + "-> " + msg);
}

运行界面如图：
简单的实现了几个接口，如果需要可以自己去实现。
