Able to get file SFTP on command line, but not using Qt Class QProcess (solved)

houmingc

i am using ubuntu desktop and is able to SFTP on the command line.
But not on Qt.Below is my debug message
"sftp 127.0.0.1"
"bash: line1: get: command not found"
Please advice.

@

void MainWindow::getFuntion()
{
QProcess myProcess;
QByteArray result;

char* ipset="127.0.0.1";
QString cmd= QString("sftp %1").arg(ipset);
qDebug()<<cmd;

//command string
myProcess.setReadChannel(QProcess::StandardOutput);
myProcess.setProcessChannelMode(QProcess::MergedChannels);
myProcess.start("bash");

if(!myProcess.waitForStarted()){
    qDebug()<<"Error: could not start terminal ::"<<endl;
}

// myProcess.write("passwrod");
myProcess.write("get asd.txt");
myProcess.closeWriteChannel(); //done writing.

while(myProcess.state()!=QProcess::NotRunning){
      myProcess.waitForFinished();
      result=myProcess.readAll();
      qDebug()<<result;
}

}

You are not using the cmd variable anywhere in this code, only for printing. So what you effectively do in the process is this:
@
bash
get asd.txt
@

And so bash complains it does not understand "get" command. You should either run sftp directly, or pass it first, before passing "get".

it work when the below code is edited.
myProcess.start(cmd);

OpenSSH prompted for password, is it possible to write the password in code first?
without the pc prompting for password?
myProcess.write("password");
