问题描述
我有一个像这样使用 QProcess 的代码.
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();
}
这将输出以下内容.
SNMPv2-SMI::enterprises.30966.1.2.1.1.1.5.10 = STRING: "0.1"
我想将此输出作为字符串读取(读取).我搜索了这个,但找不到解决方案.提前致谢.
I want to take(read) this output as string. I searched for this and I cant find the solution. Thanks in advance.
推荐答案
Did you try QByteArray QProcess::readAllStandardOutput()
docs - 这里
Did you try QByteArray QProcess::readAllStandardOutput()
docs - here
QString
可以从 QByteArray
实例化:
QString output(pingProcess.readAllStandardOutput());
正如其他人提到的,我也加入他们,你不应该使用 execute
方法并将其替换为:
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());
