将qt程序注册成服务-编程知识

将qt程序注册成服务

1、qt服务模块管理下载

qt-solutions

2、QtService项目

2.1、将qtservice拷贝到项目代码路径

在这里插入图片描述

2.2、实现服务管理

PS：响应服务的启停
CustomService.h

#include <QCoreApplication>
#include "qtservice.h"class CustomService : public QtService<QCoreApplication>
{
public:CustomService(int argc, char **argv);protected:void start();void pause();void resume();void stop();};

CustomService.cpp

#include "CustomService.h"
#include "ServiceHandle.h"CustomService::CustomService(int argc, char **argv): QtService<QCoreApplication>(argc, argv, "Custom Qt Server")
{setServiceDescription("Custom Qt Server");setServiceFlags(QtServiceBase::CanBeSuspended);
}void CustomService::start()
{QCoreApplication *app = application();SERVER_CTRL_INST.start();
}void CustomService::pause()
{SERVER_CTRL_INST.pause();
}void CustomService::resume()
{SERVER_CTRL_INST.resume();
}void CustomService::stop()
{SERVER_CTRL_INST.stop();
}

2.3、服务内部程序实现

ServiceHandle.h

#pragma once
#include "ThreadObject.h"#define SERVER_CTRL_INST ServiceHandle::Instance()
class ServiceHandle
{const std::string kProcessName = "QtService.exe";
public:static ServiceHandle& Instance(){static ServiceHandle g_inst;return g_inst;}protected:ServiceHandle();~ServiceHandle();public:void InstallService(const std::string& strServiceName = "");void StartService(const std::string& strServiceName);void StopService(const std::string& strServiceName);void UninstallService(const std::string& strServiceName);void start();void pause();void resume();void stop();private:void do_work();private:Utils::ThreadObject m_objWork;};

ServiceHandle.cpp

#include "ServiceHandle.h"
#include <fstream>
#include <QProcess>
#include <iostream>
#include <direct.h>
#include "Command.h"static int64_t g_nCnt =0;
ServiceHandle::ServiceHandle()
{
}ServiceHandle::~ServiceHandle()
{}void ServiceHandle::InstallService(const std::string& strServiceName/* = ""*/)
{char szPath[260] = { 0 };getcwd(szPath, 260);std::string strPath(szPath);strPath = strPath + "/" + kProcessName;std::cout << "Exe path: " << szPath << "\n";std::string strName = strServiceName.empty()? "CustomService": strServiceName;std::string strCmd = "sc create " + strName + " binpath=" + strPath;std::string strResponse = Utils::CommandHelper::ExecCommand(strCmd);std::cout << strResponse;// start serviceStartService(strName);
}void ServiceHandle::StartService(const std::string& strServiceName)
{std::string strCmd = "net start " + strServiceName;std::string strResponse = Utils::CommandHelper::ExecCommand(strCmd);std::cout << strResponse;
}void ServiceHandle::StopService(const std::string& strServiceName)
{std::string strCmd = "net stop " + strServiceName;std::string strResponse = Utils::CommandHelper::ExecCommand(strCmd);std::cout << strResponse;
}void ServiceHandle::UninstallService(const std::string& strServiceName)
{StopService(strServiceName);std::string strCmd = "sc delete " + strServiceName;std::string strResponse = Utils::CommandHelper::ExecCommand(strCmd);std::cout << strResponse;
}void ServiceHandle::start()
{g_nCnt = 0;m_objWork.Start(std::bind(&ServiceHandle::do_work, &SERVER_CTRL_INST), 2000);
}void ServiceHandle::pause()
{stop();
}void ServiceHandle::resume()
{start();
}void ServiceHandle::stop()
{m_objWork.Stop();
}void ServiceHandle::do_work()
{std::fstream fout("C:\\ProgramData\\CustomService.log", std::ios::out | std::ios::app);if(fout.is_open()) {fout << "Server do work: " << ++g_nCnt << "\n";fout.close();}
}

2.4、服务本身支持指令操作

PS：安装、卸载、启停以及常规启动（非服务）
main.cpp

#include <QApplication>
#include <iostream>
#include <string>
#include <map>
#include "CustomService.h"
#include "ServiceHandle.h"enum ServiceCmdType
{kServiceCmdTypeUnknown = -1,kServiceCmdTypeHelp,kServiceCmdTypeCommon,kServiceCmdTypeInstall,kServiceCmdTypeUninstall,kServiceCmdTypeStart,kServiceCmdTypeStop};std::map<std::string, ServiceCmdType> mapCmd
{{ "help", kServiceCmdTypeHelp },{ "common", kServiceCmdTypeCommon },{ "install", kServiceCmdTypeInstall },{ "uninstall", kServiceCmdTypeUninstall },{ "start", kServiceCmdTypeStart },{ "stop", kServiceCmdTypeStop }};void Usage()
{std::cout << "Usage: QtService [command] [option1] [option2]\n";std::cout << "command and options:\n";std::cout << "\tinstall [service name]:     install service, <service name> is optional, default is \"Custom Qt Server\" \n";std::cout << "\tstop [service name]:        stop service\n";std::cout << "\tstart [service name]:       start service\n";std::cout << "\tuninstall [service name]:   uninstall service\n";std::cout << "\tcommon:                     start process in common mode\n";std::cout << "\thelp:                       show usage\n";
}bool CheckValidCmd(const std::string& strCmd, ServiceCmdType& nCmd)
{bool bValid = false;auto itFind = mapCmd.find(strCmd);if(itFind != mapCmd.end()) {bValid = true;nCmd = itFind->second;}return bValid;
}// install/uninstall/start/stop service via inner action
int main(int argc, char *argv[])
{QApplication a(argc, argv);if(argc > 1) {int nIndex = 0;std::string strCmd = argv[++nIndex];ServiceCmdType nCmdType = kServiceCmdTypeUnknown;if(!CheckValidCmd(strCmd, nCmdType) || kServiceCmdTypeHelp == nCmdType) {Usage();return 0;}if(kServiceCmdTypeCommon == nCmdType) {SERVER_CTRL_INST.start();auto nCode = a.exec();SERVER_CTRL_INST.stop();return nCode;}if(argc < 3) {Usage();return 0;}std::string strServiceName = argv[++nIndex];switch(nCmdType) {case kServiceCmdTypeInstall: {SERVER_CTRL_INST.InstallService(strServiceName);break;}case kServiceCmdTypeUninstall: {SERVER_CTRL_INST.UninstallService(strServiceName);break;}case kServiceCmdTypeStart: {SERVER_CTRL_INST.StartService(strServiceName);break;}case kServiceCmdTypeStop: {SERVER_CTRL_INST.StopService(strServiceName);break;}default:break;}return 0;}// start exe with service(default)CustomService service(argc, argv);return service.exec();
}
