I have a code that uses QProcess like this.
int main(int argc, char *argv[])
{
int status=0;
QProcess pingProcess;
QString ba;
QString exec = "snmpget";
QStringList params;
params << "-v" << "2c" << "-c" << "public" << "10.18.32.52" << ".1.3.6.1.4.1.30966.1.2.1.1.1.5.10";
status=pingProcess.execute(exec, params);
pingProcess.close();
}
This outputs the following.
SNMPv2-SMI::enterprises.30966.1.2.1.1.1.5.10 = STRING: "0.1"
I want to take(read) this output as string. I searched for this and I cant find the solution. Thanks in advance.
Did you try QByteArray QProcess::readAllStandardOutput()
docs - here
QString
can be instantiated from QByteArray
:
QString output(pingProcess.readAllStandardOutput());
As others mentioned, and I join to them, you should not use execute
method and replace it with:
pingProcess.start(exec, params);
pingProcess.waitForFinished(); // sets current thread to sleep and waits for pingProcess end
QString output(pingProcess.readAllStandardOutput());
