要修改代码以实现每天创建一个新的文件,您可以按照以下步骤进行改造:
- 首先,确保您包含了必要的头文件:
#include <QDateTime>
#include <QFile>
#include <QTextStream>
- 修改
open()
函数中的文件名生成逻辑:
bool LogFile::open()
{
m_pFile = new QFile();
QDateTime currentDateTime = QDateTime::currentDateTime();
QString fileName = currentDateTime.date().toString("yyyy-MM-dd") + "_" + makeFileName() + ".txt";
m_pFile->setFileName(makeDirectory() + QDir::separator() + fileName);
if (m_pFile->open(QIODevice::WriteOnly | QIODevice::Append | QIODevice::Text))
{
ts = new QTextStream(m_pFile);
workThread = new QThread();
timer = new QTimer();
timer->setParent(nullptr);
timer->moveToThread(workThread);
QObject::connect(timer, &QTimer::timeout, this, &LogFile::onCheck, Qt::DirectConnection);
QObject::connect(workThread, &QThread::started, this, &LogFile::workThreadStarted, Qt::DirectConnection);
QObject::connect(workThread, &QThread::finished, this, &LogFile::workThreadFinished, Qt::DirectConnection);
workThread->start();
// 删除旧的日志文件
deleteOldFiles();
}
else
{
delete m_pFile;
m_pFile = nullptr;
return false;
}
return true;
}
- 修改
close()
函数来关闭并删除当前文件对象:
void LogFile::close()
{
if (workThread)
{
workThread->quit();
workThread->wait(2000);
delete workThread;
workThread = nullptr;
}
if (m_pFile)
{
dump(10000);
if(ts)
{
delete ts;
ts = nullptr;
}
m_pFile->close();
delete m_pFile;
m_pFile = nullptr;
}
}
通过这些修改,每次调用open()
函数时会生成一个新的文件名,包含当前日期和您定义的其他文件名部分。同时,在关闭日志文件时,将删除当前文件对象。
请确保在使用该代码之前已经实现了适当的目录创建和其他必要的功能。
