Qt - 显示PowerShell运行QProcess的结果

Question

I am working on a project in Qt (v4.7) which requires me to run commands through Windows PowerShell in a QProcess. This is what I have so far (with a sample command):

QString path = "C:/Windows/system32/WindowsPowerShell/v1.0/powershell.exe";
QStringList commands;
commands.append("-Command");
commands.append("invoke-command -computername mycomputer -credential myuser {ipconfig /all}");
QProcess *p = new QProcess();
process->start(path, commands);

This all seems to work and run successfully without crashing. Now, I need to be able to display the results of running this PowerShell command. I know when I run it in the cmd window it returns a lot of data, but I haven't really used QProcess at all before this, and I'm having trouble figuring out a way to show the results of the process. If anyone has any advice it would be greatly appreciated. Thanks!

Starting with your code...

QString path = "C:/Windows/system32/WindowsPowerShell/v1.0/powershell.exe";
QStringList commands;
commands.append("-Command");
commands.append("invoke-command -computername mycomputer -credential myuser {ipconfig /all}");
QProcess *p = new QProcess();

Assuming you have a slot called readyToRead() in a class MyClass, which has a pointer to the QProcess, p

connect(p, &QProcess::readyReadStandardOutput, myClass, &MyClass::readyToRead);
process->start(path, commands);

Then you'll receive notification in the slot

void MyClass::readyToRead()
{
    QString output(p->readAllStandardOutput());

    //Do something with the string
}
