1、实验名称：基于TCP的网络聊天室1•实验冃的：掌握TCP通讯协议、掌握QTcpSocket2•实验内容：使用Qt的QtcpSocket实现简单的网络聊天程序，范例如图:包括拂去其程序和客户端程序，服务端程序可以创建一个聊天室，客户端程序可以输入登陆的用户名、服务器地址以及使用的端口号，然后进入聊天室，聊天室中的每一位用户均可以看见发布的信息。3•实验方法：使用Qt的QtcpSocket,参考Qt网络编程实验。4•实验过程tcpServer端代码:#include"dialog.h"#include"ui_dialog

2、.hHDialog::Dialog(QWidget^parent):QDialog(parent),ui(newUi::Dialog){ui->setupUi(this);ui->lineEdit->setText(n8010H);port=8010;}Dialog::~Dialog(){deleteui;}voidDialog::on_newchat_clicked(){server=newServer(this,port);connect(server,SIGNAL(updateServer(QString3nt

5、onnect(tcpClientSocket,SIGNAL(disconnected(int)),this,SLOT(slotDisconnected(int)));tcpClientSocket->setSocketDescriptor(socketDescriptor);tcpClientSocketList.append(tcpClientSocket);}voidServer::updateClient(QStringmsg,intlength){emitupdateServer(msgJength);for

7、ocketList.at(i);if(item・>socketDescriptor()==descriptor){tcpClientSocketList.removeAt(i);return;}}return;Tcpclient端代码：#include"dialog.h"#include"ui_dialog.hH#includeDialog::Dialog(QWidget^parent):QDialog(parent),ui(newUi::Dialog){ui->setupUi(this);
