在 Windows 命令提示符下运行可执行文件以及参数就可以了：
cgx_STATIC.exe -b C:\Users\m3\AppData\Local\Temp\shot-277325955.fbd
但是，当通过 Golang 运行相同的可执行文件时，在可执行文件创建一些输出文件后，可执行文件将变得无响应。
<code>
// Run an executable and print its log into a file.
func RunWithLogFile(pthExe string, arg []string, fLog *os.File) error {
cmd := exec.Command(pthExe, arg...)
stdout, err := cmd.StdoutPipe()
if err != nil {
return err
}
stderr, err := cmd.StderrPipe()
if err != nil {
return err
}
err = cmd.Start()
if err != nil {
return err
}
// Stream logs:
// https://stackoverflow.com/a/48849811/3405291
scannerOut := bufio.NewScanner(stdout)
scannerErr := bufio.NewScanner(stderr)
scannerOut.Split(bufio.ScanRunes)
scannerErr.Split(bufio.ScanRunes)
for scannerOut.Scan() {
_, err = fLog.WriteString(scannerOut.Text())
if err != nil {
return err
}
}
for scannerErr.Scan() {
_, err = fLog.WriteString(scannerErr.Text())
if err != nil {
return err
}
}
if scannerOut.Err() != nil {
return err
}
if scannerErr.Err() != nil {
return err
}
err = cmd.Wait()
return err
}
</code>我想知道上面的 Go 代码是否存在某种错误或不适合运行可执行文件？
按照@BurakSerdar的建议，我在单独的goroutines中从stdout和stderr读取内容，但问题没有得到解决：
<code>
// Run an executable and print its log into a file.
func RunWithLogFile(pthExe string, arg []string, fLog *os.File) error {
cmd := exec.Command(pthExe, arg...)
stdout, err := cmd.StdoutPipe()
if err != nil {
return err
}
stderr, err := cmd.StderrPipe()
if err != nil {
return err
}
var wg sync.WaitGroup
wg.Add(2)
go streamToLogFile(stdout, fLog, &wg)
go streamToLogFile(stderr, fLog, &wg)
err = cmd.Start()
if err != nil {
return err
}
wg.Wait()
err = cmd.Wait()
return err
}
func streamToLogFile(output io.ReadCloser, fLog *os.File, wg *sync.WaitGroup) {
defer wg.Done()
scanner := bufio.NewScanner(output)
scanner.Split(bufio.ScanRunes)
for scanner.Scan() {
_, err := fLog.WriteString(scanner.Text())
if err != nil {
log.Printf("error: write to log file: %s", err.Error())
}
}
err := scanner.Err()
if err != nil {
log.Printf("error: write to log file: %s", err.Error())
}
}
</code>通过使用管理员权限运行可执行文件解决了无响应问题。我正在这样做：
A C# code runs a Go code and the Go code runs a C Code, i.e. external executable.
C 可执行文件调用一些 OpenGL GLUT 调用。也许他们需要管理员权限。
通过 C# 启动 Go 代码解决了这个问题，如下所示：//m.sbmmt.com/link/ac90e5f00f7542d99231f63fb0dfeecf< /a>
<code> public static void RunLogic(string exePath, string args, PostProcess pp)
{
cmd = new Process();
try
{
cmd.StartInfo.FileName = exePath;
cmd.StartInfo.Arguments = args;
cmd.StartInfo.UseShellExecute = true;
cmd.StartInfo.CreateNoWindow = false;
cmd.StartInfo.RedirectStandardOutput = false;
cmd.StartInfo.RedirectStandardError = false;
cmd.StartInfo.RedirectStandardInput = false;
// Vista or higher check.
// //m.sbmmt.com/link/ac90e5f00f7542d99231f63fb0dfeecf
if (System.Environment.OSVersion.Version.Major >= 6)
{
// Run with admin privileges to avoid a non-responsive executable.
cmd.StartInfo.Verb = "runas";
}
cmd.EnableRaisingEvents = true;
cmd.Exited += new EventHandler(cmd_Exited);
cmd.Exited += new EventHandler(pp);
cmd.Start();
}
catch (Exception ex)
{
RhinoApp.WriteLine("Error on process start: {0}", ex.Message);
}
}
</code>以上是在命令行上运行可执行文件没问题，但通过另一个程序运行会导致无响应的详细内容。更多信息请关注PHP中文网其他相关文章！
