類似系統的QT普通命令執行

2022-01-12 17:35:17 .NET開發

我有一個非常復雜的命令串列，它加載一個虛擬環境并在給定文本上執行幾個命令。它與 system() 一起作業正常，但與 QProcess::execute 一起失敗。這是一個無賴，因為我想使用

QProcess process; 
process.readAllStandardOutput();

在不弄亂管道的情況下讀取輸出。有沒有辦法給行程一個“愚蠢的”命令字串，它像 system() 一樣執行？

command = "bash -c \""   prepend   "\\\""    text   "\\\""   append   "\"";

std::cout << command.toStdString().c_str() << std::endl;

//qDebug() << QProcess::execute(command.toStdString().c_str());
system(command.toStdString().c_str());

QT似乎弄亂了引數：

usage: program_name [-h] [--list_models [LIST_MODELS]] [--text TEXT]

Edit1：popen 解決方案（丑陋但有效）：

FILE *fp;
char path[1035];
fp = popen(command.toStdString().c_str(), "r");
if (fp == NULL)
{
    printf("Failed to run command\n" );
    exit(1);
}

while (fgets(path, sizeof(path), fp) != NULL)
{
    QString line = path;
    if(line.contains("Keyword"))
    {
        qDebug() << "=============================";
        qDebug() << line;
        qDebug() << "=============================";
    }
}

pclose(fp);

Edit2：請求的除錯輸出

uj5u.com熱心網友回復：

正如在其他地方指出的那樣，基本問題是避免通過任何外殼會QProcess遇到一些麻煩。話雖如此，您應該能夠通過顯式呼叫 shell 來實作您想要的。

假設您通常運行的命令bash是ls -l | grep '\.'...

QProcess process;
QString shell_command = "ls -l | grep '\.'";
process.start("bash", { "-c", shell_command });

現在您可以像閱讀任何其他QProcess.

[請注意，這或多或少Qt是以前帖子的版本。]
