1.方法汇总①创建 mms.cfg 文件（Flash配置文件，默认情况下安装完Flash是没有这个文件的，需要自己创建来强制配置Flash）

该文件用文本编辑器打开，里面内容如下，意思是配置 允许本机使用Flash打开的站点

EnableAllowList=1AllowListUrlPattern=http://192.168.1.1/

AllowListUrlPattern=https://www.xxx.com/cn

②将编辑好的 mms.cfg 文件，放到以下Flash插件目录下：

C:\Windows\System32\Macromed\Flash\ （32位）

C:\Windows\SysWOW64\Macromed\Flash\ （64位）

③重新打开需要使用Flash插件的站点或者地址，Flash变为可用。

来自网上的博客，是通过鼠标相关的事件来实现的，封装起来很方便。

//Widget.h 
#ifndef WIDGET_H
#define WIDGET_H

#include <QWidget>

{
    Q_OBJECT

public:
    Widget(QWidget *parent = 0);
    ~Widget();

protected:
    //拖拽窗口
    void mousePressEvent(QMouseEvent *event);
    void mouseMoveEvent(QMouseEvent *event);
    void mouseReleaseEvent(QMouseEvent *event);

private:
    bool        m_bDrag;
    QPoint      mouseStartPoint;
    QPoint      windowTopLeftPoint;
};

#endif // WIDGET_H

//Widget.cpp

    : QWidget(parent)
    , m_bDrag(false)
{
    setWindowTitle("窗口拖拽移动");
    setFixedSize(640, 480);
}

Widget::~Widget()
{

}

/* QPoint QMouseEvent::pos() const
    Returns the position of the mouse cursor, relative to the widget that received the event.
    If you move the widget as a result of the mouse event, use the global position returned by globalPos() to avoid a shaking motion.
 */

//拖拽操作
void Widget::mousePressEvent(QMouseEvent *event)
{
    if(event->button() == Qt::LeftButton)
    {
        m_bDrag = true;
        //获得鼠标的初始位置
        mouseStartPoint = event->globalPos();
        //mouseStartPoint = event->pos();

    }
}

void Widget::mouseMoveEvent(QMouseEvent *event)
{
    if(m_bDrag)
    {
        //获得鼠标移动的距离
        QPoint distance = event->globalPos() - mouseStartPoint;
        //QPoint distance = event->pos() - mouseStartPoint;

具体步骤：

void conn()

    try

        string host="zofz.cf";
        string port="80";

        //建立基础IO接口,并初始化resolver和socket
        boost::asio::io_service io_se;
        boost::asio::ip::tcp::resolver resolver{ io_se };
        boost::asio::ip::tcp::socket socket{ io_se };

        //设定GET/POST请求
        boost::asio::streambuf request;

        // 发送request

        //声明一个容器来保存响应

        //输出body

用法：

    }
    的JSON文本转为string字符串
    */
    
    ptree root, data;
    stringstream ss;
    
    //创建data
    data.put("key", "value");
    
    //放入data
    root.put_child("data", data);
    
    //将JSON文本写入字符流
    write_json(ss, root);
    
    //读出字符串
    string json = ss.str();
}



void decode(string json)
{
    /*

    {
        "data":

    }
    的JSON文本到string中
    */
    ptree root, data;
    
    //将字符串读入字符流
    stringstream ss(json);
    
    //读出JSON格式的文本
    read_json(ss, root);
    
    //分离出data
    data = root.get_child("data");
    
    //分离出key,value
    string value = data.get & lt; string& gt; ("key");
