为了继续处理随机异常（偶尔会发生），我像这样启动chromedriver

private IWebDriver StartBrowserChromeHeadless()
{
   var maxRetries = 3;
   var retries = 0;

   while(true)
   {
      try
      {
         return StartBrowserChromeHeadlessDriver();
      }
      catch
      {
         if (retries++ == maxRetries)
         {
            throw;
         }
         Thread.Sleep(5000);
      }
   }
}

private IWebDriver StartBrowserChromeHeadlessDriver()
{
    var chromeOptions = new ChromeOptions();
    chromeOptions.AddArgument("--headless=new");
    chromeOptions.AddArgument("--window-size=1920,1080");
    chromeOptions.AddUserProfilePreference("download.default_directory", downloadFolder);

    var chromeDownload = new Dictionary<string, object>
    {
        { "behavior", "allow" },
        { "downloadPath", downloadFolder }
    };

    var driver = new ChromeDriver(driverFolder, chromeOptions, TimeSpan.FromSeconds(timeoutSecs));
    driver.ExecuteCdpCommand("Browser.setDownloadBehavior", chromeDownload);
    return driver;
}
