c++ - SSH在QProcess中不起作用，但在控制台中起作用

我有以下代码:

QProcess* proc = new QProcess();
proc->start("cmd.exe");
proc->write("ssh\n");
proc->closeWriteChannel();
proc->waitForFinished();
QTextCodec *codec = QTextCodec::codecForName("IBM 866");
ui->textEditNormal->setText(codec->toUnicode(proc->readAllStandardOutput()));
ui->textEditError->setText(codec->toUnicode(proc->readAllStandardError()));

用StandartError编写:

'ssh' is not recognized as an internal or external command

如果我用cmd.exe重复所有内容，那么一切都很好
如何解决？

最佳答案

也许您应该等待进程开始后再进行写入。下面的示例执行类似的操作。我没有安装ssh，所以我在Windows计算机上发出了dir。就试一试吧。

#include <QApplication>
#include <QDebug>
#include <QTextBrowser>
#include <QProcess>

int main(int argc, char* argv[])
{
    QApplication a(argc, argv);
    auto process = new QProcess;
    auto view = new QTextBrowser;
    process->setWorkingDirectory("C:/Temp");
    QObject::connect(process, &QProcess::readyReadStandardOutput, [process,view]() {
        auto output=process->readAllStandardOutput();
        view->append(output);
    });
    QObject::connect(process, &QProcess::readyReadStandardError, [process,view]() {
        auto output=process->readAllStandardError();
        view->append(output);
    });
    process->start("cmd.exe");
    process->setProcessChannelMode(QProcess::MergedChannels);

    process->waitForStarted();
    process->write("dir\n");
    qDebug() << process->error();
    view->show();
    return a.exec();
}
