Catch network errors using Awesomium

I am creating a headless browser using Awesomium. I want the browser to return Network Error codes, so I know how/why it's breaking.

using (WebSession session = WebCore.CreateWebSession(new WebPreferences() CustomCSS = "::-webkit-scrollbar visibility: hidden; " ))

using (WebView browserTab = WebCore.CreateWebView(1100, 600, session))

Console.WriteLine($"Starting WebCore vWebCore.Version");
BadExample(browserTab, baseURL);



static void BadExample(WebView browser, Uri url)
browser.Source = (url + "/anyhing").ToUri();
browser.LoadingFrameComplete += (sender, returnFrame) =>

//NetError Code
;



How do I use enum NetError to return the values I want?

You should subscribe to event IWebView.LoadingFrameFailed (browser in your case).

IWebView.LoadingFrameFailed

As long as there can be many frames on a page, the event will fire for every frame. Below is a snippet that I use in my project.

private void ViewOnLoadingFrameFailed(object sender, LoadingFrameFailedEventArgs e)

if (e.IsMainFrame)

var error = (NetError) e.ErrorCode;
Logger.ErrorFormat("main frame loading failed: 0-1", e.ErrorCode, e.ErrorDescription);

else

Logger.WarnFormat("frame #0 loading failed: 1 - 2", e.FrameId, e.ErrorCode, e.ErrorDescription);
