qt - 从 TCP Client (NON QT) 到 TCP Server (QT) 的发送结构

Question

这是我常用的头文件。

/*Type of data being sent to HMI*/
enum HMIDataType{
    Climate = 0x12
};

#define MIN_DATA_CLIMATE 0x00000200u
#define MAX_DATA_CLIMATE 0x000002ffu

/*Types of Climate Data*/
enum enumClimateData
{
    //! @brief Driver temperature
    //! Type : float
    DP_DriverTemperature_Float = MIN_DATA_CLIMATE
};


/*Climate Data to be sent to HMI*/
struct ClimateData{
   enumClimateData type;
   struct{
       double ddata;
       int idata;
       bool bdata;
   }body;
};

/*HMI data to be sent*/
struct HMIData{
   HMIDataType type;
   struct{
       ClimateData climatedata;
   }body;
};

发送方应用程序是一个通过 TCP 套接字发送数据的非 QT TCP 客户端

/* Creating Data */
HMIData data;
data.type = Climate;
data.body.climatedata.type = DP_DriverTemperature_Float;
data.body.climatedata.body.ddata = 12.23;
SendDataToHMI(&data);

发送它：

void SendDataToHMI(HMIData * data)
{
    /* send the message line to the server */
    size_t n = write(sockfd, (char*)data, sizeof(HMIData));
    if (n < 0)
      printf("ERROR writing to socket");
}

在我的基于 QT 的 TCP 服务器中但是我无法取回数据结构。

不起作用：

HMIData* m= new HMIData();
// get the information
qint64 Data = socket->read((char*)m, sizeof(HMIData));
qDebug() << "Type: " << (uint)m->body.climatedata.type << "Data: " << m->body.climatedata.body.ddata;

不起作用：

QByteArray Data = socket->readAll();

QDataStream dstream (Data);
HMIData m;
while(!dstream.atEnd())
{
    dstream >> m;
}
