读取 QProcess 输出到字符串

2021-12-09 00:00:00 stdout qt qprocess c++ qstring

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.

Did you try QByteArray QProcess::readAllStandardOutput() docs - 这里

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());
