Selenium C# network traffic logging example

NetworkInterception.cs

public async Task LogNetworkRequests(IWebDriver driver)
{
    INetwork interceptor = driver.Manage().Network;
    interceptor.NetworkRequestSent += OnNetworkRequestSent;
    interceptor.NetworkResponseReceived += OnNetworkResponseReceived;
    await interceptor.StartMonitoring();
    driver.Url = "http://the-internet.herokuapp.com/redirect";
    await interceptor.StopMonitoring();
}

private void OnNetworkRequestSent(object sender, NetworkRequestSentEventArgs e)
{
    StringBuilder builder = new StringBuilder();
    builder.AppendFormat("Request {0}", e.RequestId).AppendLine();
    builder.AppendLine("--------------------------------");
    builder.AppendFormat("{0} {1}", e.RequestMethod, e.RequestUrl).AppendLine();
    foreach (KeyValuePair<string, string> header in e.RequestHeaders)
    {
        builder.AppendFormat("{0}: {1}", header.Key, header.Value).AppendLine();
    }
    builder.AppendLine("--------------------------------");
    builder.AppendLine();
    Console.WriteLine(builder.ToString());
}

private void OnNetworkResponseReceived(object sender, NetworkResponseReceivedEventArgs e)
{
    StringBuilder builder = new StringBuilder();
    builder.AppendFormat("Response {0}", e.RequestId).AppendLine();
    builder.AppendLine("--------------------------------");
    builder.AppendFormat("{0} {1}", e.ResponseStatusCode, e.ResponseUrl).AppendLine();
    foreach (KeyValuePair<string, string> header in e.ResponseHeaders)
    {
        builder.AppendFormat("{0}: {1}", header.Key, header.Value).AppendLine();
    }

    if (e.ResponseResourceType == "Document")
    {
       builder.AppendLine(e.ResponseBody);
    }
    else if (e.ResponseResourceType == "Script")
    {
        builder.AppendLine("<JavaScript content>");
    }
    else if (e.ResponseResourceType == "Stylesheet")
    {
        builder.AppendLine("<stylesheet content>");
    }
    else if (e.ResponseResourceType == "Image")
    {
        builder.AppendLine("<image>");
    }
    else
    {
        builder.AppendFormat("Content type: {0}", e.ResponseResourceType).AppendLine();
    }

    builder.AppendLine("--------------------------------");
    Console.WriteLine(builder.ToString());
}

This gist seems alright, but the exception seems to be due to an issue in Selenium itself. A similar bug has been reported under SeleniumHQ/selenium#10054 (comment)

it work for me

Thanks your code, the best...

Thank you.

Hi,
I am getting below error.

I am getting above while running the code. "await interceptor.StartMonitoring();"
