dcmtk scp代码实例

DCMTK (Digital Imaging and Communications in Medicine Toolkit) 是一组开源软件库，用于处理医学图像文件，包括DICOM (Digital Imaging and Communication in Medicine) 格式。"scp" 是 "Secure Copy" 的缩写，在 DCMTK 中通常用于安全地通过 SCP 协议传输文件。

下面是一个简单的 DCMTK SCP 脚本示例，这个脚本用于从远程服务器下载DICOM文件：

#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dcuid.h"
#include "dcmtk/dcmnet/dimse.h"
#include "dcmtk/dcmnet/scp.h"

int main(int argc, char *argv[])
{
    try
    {
        OFConsoleApplication consoleApp(argc, argv);

        // 初始化SCP服务
        DcmNet::OFCondition cond = DcmScp::createServer("localhost", 11112);
        if (cond.bad())
        {
            OFLOG_FATAL(dclog, "Creation of SCP service failed with error code " << cond.errorCode());
            return 1;
        }

        // 开始接收连接并处理请求
        while (!consoleApp.cmdIsPending())
        {
            DcmDataset* dataset = new DcmDataset();
            DcmScp::status_t status = DcmScp::receive(dataset);
            if (status == EUSUCCESS)
            {
                // 操作成功，例如存储到本地目录
                char filename[256];
                sprintf(filename, "received-%d.dcm", dataset->getAndRemove(DCMStudyInstanceUID).value());

                // 将文件保存到本地
                std::ofstream file(filename, std::ios::binary);
                file.write(dataset->storage(), dataset->lengthOfStorage());
                delete dataset;

                OFLOG_INFO(dclog, "Received DICOM file '" << filename << "'");
            }
            else if (status != EBUSY)
            {
                OFLOG_ERROR(dclog, "Error receiving file: " << DcmScp::statusToString(status));
            }
        }

        // 清理资源
        DcmScp::deleteServer();
    }
    catch (const std::exception &e)
    {
        OFLOG_FATAL(dclog, "Exception caught: " << e.what());
        return 1;
    }

    return 0;
}
