Qt Socket通信

服务器端（封装成类），此部分为本人同事写的，在这里先谢谢我的这位同事，cpp：

#include "server.h"

#include<QMessageBox>

#include<QDebug>

Server::Server(QObject *parent,int port)

    :QTcpServer(parent)

{
 
 

    listen(QHostAddress::Any,port);

}

int Server::getAddClient()

{
 
 

    return addClient;

}

void Server::setAddClient(int value)

{
 
 

    addClient = value;

}

int Server::getDeleteClient()

{
 
 

    return deleteClient;

}

void Server::setDeleteClient(int value)

{
 
 

    deleteClient = value;

}

int Server::getClientAllNum()

{
 
 

    return clientAllNum;

}

void Server::setClientAllNum(int value)

{
 
 

    clientAllNum = value;

}

int Server::clientnum=0;

int Server::clientAllNum=0;

int Server::deleteClient=0;

int Server::addClient=0;

//获取客户端数量

int Server::getClientnum()

{
 
 

    return clientnum;

}

//设置客户端数量

void Server::setClientnum(int value)

{
 
 

    clientnum = value;

}

//发送信息到客户端

void Server::sendMessageToClient(QString msg)

{
 
 

    int listLengh=tcpClientSocketList.count();

    if(clientnum<=listLengh && listLengh!=0)

    {
 
 

        QTcpSocket *item = tcpClientSocketList.at(clientnum);

        QByteArray datasend =msg.toLocal8Bit();

        item->write(datasend);

//        std::string msgstd=msg.toStdString();

//        const char *msgtoc=msgstd.c_str();

//        if(item->write(msgtoc,msg.length())!=msg.length())

//        {
  
  

//            qDebug()<<"msgupdate1";

//        }

    }

}

//发送信息到所有客户端

void Server::sendMessageToAllClient(QString msg)
