如何在TuesPechkin

Question

如果TuesPechkin为PDF生成的网页返回HTTP错误404或500，我想抛出异常。我不想为看起来很友好的HTML错误页面获取PDF文件。

它已尝试过EventHandler（请参阅下面的代码），但它们都没有捕获错误代码或错误消息。引发ErrorEvent的唯一时间是我传入一个伪造域名的网址，例如http://www.google.bogus

Pechkin在SynchronizedPechkin中有一个名为'HttpErrorCode'的类属性。 TuesPechkin在哪里？

public ActionResult Index()
{
    var messages = new StringBuilder();

    IConverter converter =
        new ThreadSafeConverter(
            new RemotingToolset<PdfToolset>(
                new Win64EmbeddedDeployment(
                    new TempFolderDeployment())));

    var obj = new ObjectSettings();
    obj.PageUrl = "http://www.google.com/dummy";

    var doc = new HtmlToPdfDocument();
    doc.Objects.Add(obj);

    converter.Error += new EventHandler<ErrorEventArgs>(converter_Error);
    converter.Warning += new EventHandler<WarningEventArgs>(converter_Warning);
    converter.PhaseChange += new EventHandler<PhaseChangeEventArgs>(converter_PhaseChange);
    converter.Begin += new EventHandler<BeginEventArgs>(converter_Begin);

    byte[] pdfBinary = null;
    try
    {
        pdfBinary = converter.Convert(doc);
    }
    catch (Exception e)
    {
        messages.AppendLine(e.Message);
    }
    finally
    {
        converter.Error -= new EventHandler<ErrorEventArgs>(converter_Error);
        converter.Warning -= new EventHandler<WarningEventArgs>(converter_Warning);
        converter.PhaseChange -= new EventHandler<PhaseChangeEventArgs>(converter_PhaseChange);
        converter.Begin -= new EventHandler<BeginEventArgs>(converter_Begin);
    }

    if (messages.Length > 0)
    {
        throw new ApplicationException(messages.ToString());
    }
    return File(pdfBinary, "application/pdf");
}


void converter_Begin(object send, BeginEventArgs e)
{
    messages.AppendLine(e.ToString());
}

void converter_PhaseChange(object send, PhaseChangeEventArgs e)
{
    messages.AppendLine(e.PhaseDescription);
}

void converter_Warning(object send, WarningEventArgs e)
{
    messages.AppendLine(e.WarningMessage);
}

void converter_Error(object sender, ErrorEventArgs e)
{
    messages.AppendLine(e.ErrorMessage);
}
