Select folder and upload all files from folder to server

developerNancy

I am trying to upload all folder files (data) to server and move uploaded file into sent folder

I have done with single file selection Here is my code Now I select the folder and upload all files of folder.

  QErrorMessage msg;
   QString usersfilename = QFileDialog::getOpenFileName();
   QDir dir = QFileInfo(usersfilename).absoluteDir();
   qDebug() << dir;
   qDebug() << usersfilename;
   this->ui->uploadEdit->setText(usersfilename);
     QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);
    QHttpPart imagePart;
    imagePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("text/plain"));
  
    imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data;name=usersfilename;filename="+usersfilename));
    QHttpPart textPart;

    textPart.setBody("file");


QFile *file = new QFile(usersfilename);
    file->open(QIODevice::ReadOnly);
    imagePart.setBodyDevice(file);
    file->setParent(multiPart); 
     multiPart->append(textPart);
    multiPart->append(imagePart);

    QUrl url("my url");
    QNetworkRequest request(url);
    qDebug() <<url;

    QNetworkAccessManager *networkManager= new QNetworkAccessManager;
    QNetworkReply * reply = networkManager->post(request, multiPart);
    multiPart->setParent(reply); // delete the multiPart with the reply
  
   qDebug() <<reply;
     if (reply->error() == QNetworkReply::NoError)
          {

              QString strReply = (QString)reply->readAll();
              qDebug() << "Response:" << strReply;
              QJsonDocument jsonResponse = QJsonDocument::fromJson(strReply.toUtf8());
              QJsonObject jsonObj = jsonResponse.object();
              QJsonObject result=jsonObj["result"].toObject();

              if(jsonObj["error"].toBool()==false)

              {
                  QJsonObject data=result["data"].toObject();
                  QMessageBox msgBox;
                  msgBox.setText("model is uploaded");
                  msgBox.exec();
              }
              else
              {
                  QErrorMessage msg;
                  msg.showMessage("Error during upload proces");
                  msg.exec();
              }
              delete reply;

          }
}

It might be helpful to tell also others what kind of problem you have with this, since you have posted it as a question.

Hi

To get all files in the folder you can do ( and sub folders...)

QDirIterator it(dir, QStringList() << "*.*", QDir::Files, QDirIterator::Subdirectories);
while (it.hasNext())
    qDebug() << it.next();  // this just lists them. you should move upload code to function and call it pr file.

developerNancy

@mrjj mainwindow.cpp:131: error: no matching function for call to 'QDirIterator::QDirIterator(QDir&, QStringList&, QDir::Filter, QDirIterator::IteratorFlag)'
QDirIterator it(dir, QStringList() << ".", QDir::Files, QDirIterator::Subdirectories);

issue after including QDir
^

koahnig

@developerNancy

Did you include QDirIterator header?

developerNancy

@koahnig Yes

koahnig

@developerNancy

You need to post a larger section of the code where the problem is.
Also a larger stretch of the error messages are helpful.

What is the OS and compiler you are using?

developerNancy

@koahnig I am using ubuntu I have already posted the code to upload file on server and for select the single file my code is void

  void MainWindow::selectFileDownload()
 {

     QString downloadlocation = QFileDialog::getOpenFileName();
    QDir dir = QFileInfo(downloadlocation).absoluteDir();
    qDebug() << dir;
    qDebug() << downloadlocation;
     this->downloadLine->setText(downloadlocation);

}

jsulm

@developerNancy There is no such constructor. Please check the documentation: http://doc.qt.io/qt-5.8/qdiriterator.html

developerNancy

@jsulm I have not Implemented directory yet it is a selected file method.

developerNancy

@developerNancy
Using this code
QDirIterator UploadFolderFiles(UploadFolder, QDirIterator::Subdirectories );
while (UploadFolderFiles.hasNext()) {
qDebug() << UploadFolderFiles.next();
}

My output is this:
/Desktop/testingQT"
/Desktop/testingQT/Linuxapp"
/Desktop/testingQT/.."
/Desktop/testingQT/."
/Desktop/testingQT/dfgdggd"

But I want only files.

mrjj

@developerNancy

well u left out the list of files u want
so that seems to mean no files when u dont give it a list.

developerNancy

@mrjj My output is this:
/Desktop/testingQT"
/Desktop/testingQT/Linuxapp"
/Desktop/testingQT/.."
/Desktop/testingQT/."
/Desktop/testingQT/dfgdggd"

But there is . and .. also I want only files

developerNancy

@mrjj I want files only without . and .. means 1st is file name and second null and third also null and fourth is file name.

/Desktop/testingQT/Linuxapp"
/Desktop/testingQT/.."
/Desktop/testingQT/."
/Desktop/testingQT/dfgdggd"

@developerNancy
You may have a look at http://doc.qt.io/qt-5/qdiriterator.html#QDirIterator-2 and http://doc.qt.io/qt-5/qdir.html#Filter-enum

developerNancy

@the_ I am new in qt I don't know how to implement too confused

the_

@developerNancy
Which part of the documentation don't you understand and what did you try so far?

developerNancy

@the_ I have almost done but I want only files......

the_

@developerNancy

If you only want the files within a folder just apply the correct QDir::Filters to the QDirIterator.
Just a guess: QDir::Files as can be found in http://doc.qt.io/qt-5/qdir.html#Filter-enum

--EDIT

QDir::NoDotAndDotDot is not neccessary if you use QDir::Files as . and .. are folders and not files. my bad, sorry

developerNancy

@developerNancy Would be great if you could provide me with some working example of this.

Thanks
