我使用了旧的QtService代码：https://github.com/qtproject/qt-solutions/tree/master/qtservice并创建了一个服务来运行npm start命令，该命令将在Windows启动时启动我的网站。当添加-exec参数时，在app模式下启动它运行得很好，但当它作为服务运行时，它什么也不做。在调试过程中，我发现它没有正确地进入服务事件循环。因此，我创建了一个小示例，它应该将一些文本写入txt文件来说明这个问题。

代码：

• 保险服务.h*

#ifndef INSURANCESERVICE_H
#define INSURANCESERVICE_H

#include <QCoreApplication>
#include <QObject>
#include <QThread>
#include <QDebug>
#include "qtservice.h"
#include "servicelogger.h"

class InsuranceService : public QtService<QCoreApplication>
{
    Q_GADGET
public:
    InsuranceService(int argc, char *argv[]);
    ~InsuranceService();

private:
    void start();
    void stop();
    void pause();
    void resume();
    void processCommand(int code);
    void createApplication(int &argc, char *argv[]);
};

#endif // INSURANCESERVICE_H

• 保险服务.cpp*

#include "insuranceservice.h"

InsuranceService::InsuranceService(int argc, char *argv[]) : QtService<QCoreApplication>(argc, argv, "InsuranceService")
{
    std::cout << serviceName().toStdString().c_str() << std::endl;
    setServiceDescription("Test service");
    setServiceFlags(QtServiceBase::CanBeSuspended);
    //setStartupType(QtServiceController::AutoStartup);
}

void InsuranceService::start()
{
    try {
        QCoreApplication *insuranceApp = application();
        QFile *logFile = new QFile(ServiceLogger::getLogPath(), insuranceApp); 
        logFile->open(QIODevice::WriteOnly | QIODevice::Append);
        ServiceLogger::writeLog(logFile, QString("Test...").toUtf8());
        logFile->close();
        logFile->deleteLater();
    } catch (...) {
        qCritical() << "Failed to start the service!!!";
    }
}

void InsuranceService::stop()
{

}

void InsuranceService::pause()
{

}

void InsuranceService::resume()
{

}

void InsuranceService::processCommand(int code)
{
    Q_UNUSED(code);
}

void InsuranceService::createApplication(int &argc, char *argv[])
{
    QtService::createApplication(argc, argv);
}

InsuranceService::~InsuranceService()
{

}

main.cpp

#include <QCoreApplication>
#include "insuranceservice.h"

int main(int argc, char *argv[])
{
    InsuranceService service(argc, argv);
    return service.exec();
}

如何正确进入服务事件循环？

更新时间：

我尝试使用内置的logMessage方法运行此服务：

void InsuranceService::start()
{
    logMessage("The start method executing....", QtServiceBase::Success, 0, 0);
    QFile *logFile = new QFile(ServiceLogger::getLogPath());
    logFile->open(QIODevice::WriteOnly | QIODevice::Append);
    ServiceLogger::writeLog(logFile, QString("Test...").toUtf8());
    logFile->close();
    logFile->deleteLater();
}

在Event Viewer中，它报告：* start方法正在执行....*
但由于某些原因，logMessage()以下的所有内容都不会执行。应该创建的日志文件不存在。问题可能是logMessage()在一个示例上运行，而QFile在另一个示例上创建/运行。我需要以某种方式连接到正确的示例。
谢谢你。
