Question

我正在使用chrome Webdriver在页面上截取屏幕截图，如果我使用“无头”参数我会收到此错误：

    [1127/115120.051:INFO:CONSOLE(157)] "Deprecation warning: moment 
    construction falls back to js Date. 
    This is discouraged and will be removed in upcoming major release. 
    Please refer to https://github.com/moment/moment/issues/1407 for more info.

我不确定错误和信息消息是否相关。同样的事情发生在使用phantomJS，但如果显示chrome窗口，则工作正常，尽管这不是一个选项，因为每次截屏时，chrome steals焦点。

这就是我正在尝试的事情：

         static void Main()
        {
             ChromeOptions options = new ChromeOptions();
             options.AddArgument("--disable-notifications");
             options.AddArguments("--disable-gpu");
             options.AddArgument("--headless");

             var driver = new ChromeDriver(options);

             driver.Url = "https://uk.tradingview.com/chart/?symbol=FX:GBPUSD";

             var webElement = driver.FindElementByClassName("chart-widget");
             string fileName = DateTime.Now.ToString("yyyy-MM-dd HH-mm-ss") + ".jpg";
             Byte[] byteArray = ((ITakesScreenshot)driver).GetScreenshot().AsByteArray;
             System.Drawing.Bitmap screenshot = new System.Drawing.Bitmap(new System.IO.MemoryStream(byteArray));
        }

错误发生在地址传递给driver.Url。

时

任何想法如何解决或解决它？
