从c++程序中的python程序中检索stderr

#include <iostream>
#include <cstdio>

int main() {
    FILE* pipe = popen("python your_python_script.py 2>&1", "r");
    if (!pipe) {
        std::cerr << "Failed to execute Python script." << std::endl;
        return 1;
    }

    char buffer[128];
    std::string result = "";
    while (!feof(pipe)) {
        if (fgets(buffer, 128, pipe) != NULL)
            result += buffer;
    }

    pclose(pipe);

    std::cout << "Python script stderr: " << result << std::endl;

    return 0;
}
