如何在c++的quickfixc中动态地约定SenderCompID和TargetCompID？

#include <quickfix/Application.h>
#include <quickfix/SessionSettings.h>

class MyApplication : public FIX::Application
{
public:
    void onCreate(const FIX::SessionID& sessionID) override
    {
        // 读取配置文件
        FIX::SessionSettings settings("config.cfg");
        
        // 获取SenderCompID和TargetCompID的值
        std::string senderCompID = settings.get(sessionID).getString("SenderCompID");
        std::string targetCompID = settings.get(sessionID).getString("TargetCompID");
        
        // 动态设置会话的SenderCompID和TargetCompID属性
        FIX::Session::get(sessionID).setSenderCompID(senderCompID);
        FIX::Session::get(sessionID).setTargetCompID(targetCompID);
    }
    
    // 其他方法的实现...
};

int main()
{
    // 创建应用程序对象
    MyApplication application;
    
    // 启动应用程序
    FIX::SessionSettings settings("config.cfg");
    FIX::FileStoreFactory storeFactory(settings);
    FIX::ScreenLogFactory logFactory(settings);
    FIX::SocketAcceptor acceptor(application, storeFactory, settings, logFactory);
    acceptor.start();
    
    // 等待应用程序退出
    while (true)
    {
        // ...
    }
    
    return 0;
}
