"Roi_Channel"));
std::string Roi_Content = request->getHeader("Roi_Content");
int roiStyle = std::stoi(request->getHeader("roiStyle"));
int roiPosition_x = std::stoi(request->getHeader("roiPosition_x"));
int roiPosition_y = std::stoi(request->getHeader("roiPosition_y"));

然后将这五个元素存放到结构体数组中：

struct RoiData {
    int Roi_Channel;
    std::string Roi_Content;
    int roiStyle;
    int roiPosition_x;
    int roiPosition_y;
};

std::vector<RoiData> data;

RoiData newData;
newData.Roi_Channel = Roi_Channel;
newData.Roi_Content = Roi_Content;
newData.roiStyle = roiStyle;
newData.roiPosition_x = roiPosition_x ;
newData.roiPosition_y  =  roiPosition_y ;

data.push_back(newData);

每次收到新的数据时，将其存放到结构体数组中即可。
