我目前正在尝试创建新的NodeJS进程,并且在其运行时,将其控制台输出放入我的winform文本框中。
无论何时执行此过程,它都会冻结主线程,就像表单正在等待该过程退出一样。关闭该过程后,即会将控制台输出添加到文本框中。
我想要实现的是同时让该节点进程在后台运行,并在文本框中输出任何内容。
我设法在不冻结主线程的情况下运行控制台,但是输出仅在进程关闭时显示
我当前的代码:
private void Btn_connect_Click(object sender, EventArgs e)
{
if(backgroundWorker1.IsBusy != true)
{
backgroundWorker1.RunWorkerAsync();
}
}
private void BackgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
var worker = sender as BackgroundWorker;
nodeProcess = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = "node.exe";
startInfo.Arguments = @"path" + " arg1 arg2 arg3";
startInfo.UseShellExecute = false;
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.RedirectStandardOutput = true;
nodeProcess.StartInfo = startInfo;
nodeProcess.Start();
while (worker.CancellationPending != true)
{
Thread.Sleep(200);
AddText(nodeProcess.StandardOutput.ReadToEnd());
worker.ReportProgress(1);
}
e.Cancel = true;
}
public void AddText(string text)
{
if(txt_log.InvokeRequired)
{
txt_log.Invoke(new Action<string>(AddText), new object[] { text });
return;
}
txt_log.Text += "\n " + text;
}
答案 0 :(得分:1)
您可以尝试使用Process.BeginOutputReadLine
,Process.OutputDataReceived
和Process.Exited
代替Unable to fetch auth token. Error: HTTPSConnectionPool(host='login.microsoftonline.com', port=443): Max retries exceeded with url: /common/oauth2/v2.0/token (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')])")))
