专 业：计算机科学与技术
授课教师：贺刚
完成日期：2020.5.27
实验一：TCP套接字编程
内容：
1、利用阻塞模型的开发TCP通信客户端程序。
2、在程序中必须处理粘连包和残缺包问题。
3、自定义应用层协议。
4、采用多线程开发技术。
实验代码：
服务器端：
#include "iostream.h"
return 0;
}
DWORD WINAPI ThreadProc(LPVOID lpParam)
{
SOCKET client=(SOCKET)(lpParam);
int iLenth=0;
int VectorLen=0;
char recBuff[1024]="";
cout<<"thread:"<<client<<endl;
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX < 0xF000);
CMenu* pSysMenu = GetSystemMenu(FALSE);
if(pSysMenu != NULL)
{
CString strAboutMenu;
if(sClient == INVALID_SOCKET)
{
cout<<"Failed accept()"<<endl;
continue;
}
//sClientVector.push_back(sClient);
cout<<"接受到一个连接: "<<inet_ntoa(remoteAddr.sin_addr)<<endl;
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
}
voidCWork1Dlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CWork1Dlg)
}
else
{
closesocket(client);
return 0; //退出线程
}
}
closesocket(client);
return 0;
}
客户端：
基于阻塞模式的客户端：
Dlg主类：
#include"stdafx.h"
#include"work1.h"
#include"work1Dlg.h"
CAboutDlg();
// Dialog Data
//{{AFX_DATA(CAboutDlg)
enum{ IDD = IDD_ABOUTBOX };
//}}AFX_DATA
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CAboutDlg)
