在Qt应用程序中获取当前工作目录

刚刚测试过，QDir::currentPath()确实返回了我调用可执行文件的路径。

符号链接不"存在"。如果你从那个路径执行一个exe，你实际上是从符号链接指向的路径执行它。

您是否尝试过QCoreApplication::applicationDirPath()

qDebug() << "App path : " << qApp->applicationDirPath();

为了补充KaZ的答案，每当我创建QML应用程序时，我倾向于将此添加到主c++

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QStandardPaths>
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
// get the applications dir path and expose it to QML 
QUrl appPath(QString("%1").arg(app.applicationDirPath()));
engine.rootContext()->setContextProperty("appPath", appPath);

// Get the QStandardPaths home location and expose it to QML 
QUrl userPath;
   const QStringList usersLocation = QStandardPaths::standardLocations(QStandardPaths::HomeLocation);
   if (usersLocation.isEmpty())
       userPath = appPath.resolved(QUrl("/home/"));
   else
      userPath = QString("%1").arg(usersLocation.first());
   engine.rootContext()->setContextProperty("userPath", userPath);
   QUrl imagePath;
      const QStringList picturesLocation = QStandardPaths::standardLocations(QStandardPaths::PicturesLocation);
      if (picturesLocation.isEmpty())
          imagePath = appPath.resolved(QUrl("images"));
      else
          imagePath = QString("%1").arg(picturesLocation.first());
      engine.rootContext()->setContextProperty("imagePath", imagePath);
      QUrl videoPath;
      const QStringList moviesLocation = QStandardPaths::standardLocations(QStandardPaths::MoviesLocation);
      if (moviesLocation.isEmpty())
          videoPath = appPath.resolved(QUrl("./"));
      else
          videoPath = QString("%1").arg(moviesLocation.first());
      engine.rootContext()->setContextProperty("videoPath", videoPath);
      QUrl homePath;
      const QStringList homesLocation = QStandardPaths::standardLocations(QStandardPaths::HomeLocation);
      if (homesLocation.isEmpty())
          homePath = appPath.resolved(QUrl("/"));
      else
          homePath = QString("%1").arg(homesLocation.first());
      engine.rootContext()->setContextProperty("homePath", homePath);
      QUrl desktopPath;
      const QStringList desktopsLocation = QStandardPaths::standardLocations(QStandardPaths::DesktopLocation);
      if (desktopsLocation.isEmpty())
          desktopPath = appPath.resolved(QUrl("/"));
      else
          desktopPath = QString("%1").arg(desktopsLocation.first());
      engine.rootContext()->setContextProperty("desktopPath", desktopPath);
      QUrl docPath;
      const QStringList docsLocation = QStandardPaths::standardLocations(QStandardPaths::DocumentsLocation);
      if (docsLocation.isEmpty())
          docPath = appPath.resolved(QUrl("/"));
      else
          docPath = QString("%1").arg(docsLocation.first());
      engine.rootContext()->setContextProperty("docPath", docPath);

      QUrl tempPath;
      const QStringList tempsLocation = QStandardPaths::standardLocations(QStandardPaths::TempLocation);
      if (tempsLocation.isEmpty())
          tempPath = appPath.resolved(QUrl("/"));
      else
          tempPath = QString("%1").arg(tempsLocation.first());
      engine.rootContext()->setContextProperty("tempPath", tempPath);
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
return app.exec();
}

在QML中使用

....
........
............
Text{
text:"This is the applications path: " + appPath
+ "nThis is the users home directory: " + homePath
+ "nThis is the Desktop path: " desktopPath;
}

感谢RedX和Kaz的回答。我不明白为什么我给出了exe的路径。我发现了另一种方法:

QString pwd("");
char * PWD;
PWD = getenv ("PWD");
pwd.append(PWD);
cout << "Working directory : " << pwd << flush;

它没有一行那么优雅…

我在Windows下运行Qt 5.5, QDir的默认构造函数似乎拾取当前工作目录，而不是应用程序目录。

我不确定getenv PWD是否会跨平台工作，我认为当shell启动应用程序时，它被设置为当前工作目录，不包括应用程序本身所做的任何工作目录更改(这可能是OP看到这种行为的原因)。

所以我想我应该添加一些其他的方法，应该给你当前的工作目录(而不是应用程序的二进制位置):

// using where a relative filename will end up
QFileInfo fi("temp");
cout << fi.absolutePath() << endl;
// explicitly using the relative name of the current working directory
QDir dir(".");
cout << dir.absolutePath() << endl;
