Question:

C# bgResponseObject and HttpEndReceiveEventHandler. bgResultString where are you?

Oct 31 '14 at 05:16

I've search for samples, and in forums and documentation, but nothing mentions how to use Chilkat http asynchronously.

I've tried synchronously using QuickGet and confirm that my endpoint returns a response.

I debug the below code and confirm that a background Task is running and that it does notice there is an end and a http response 200. but none of my attempts to get the bgResultstring have been successful.

I set up HttpEndReceiveEventHandler, I've tried a horrible WHILE loop (sigh!) even.

simple version of code below:

class Program
{
    public static void Main(string[] args)
    {

    using (var chillkatHttpBgClient = new Chilkat.Http())
    {
        if (!chillkatHttpBgClient.IsUnlocked()) chillkatHttpBgClient.UnlockComponent(chillkatKey);
        chillkatHttpBgClient.UseBgThread = true;
        chillkatHttpBgClient.OnHttpEndReceive += new Chilkat.Http.HttpEndReceiveEventHandler(HttpEndReceiveEventHandlerEvent);

        var bgHttpResponseByteArray = chillkatHttpBgClient.QuickGet(requestUri);
        Console.WriteLine("Press enter to continue.");
        Console.ReadLine();
        chillkatHttpBgClient.OnHttpEndReceive -= new Chilkat.Http.HttpEndReceiveEventHandler(HttpEndReceiveEventHandlerEvent);
    }
}
public void HttpEndReceiveEventHandlerEvent(object response, Chilkat.StatusEventArgs status)
{
    Console.WriteLine("response: " + response.ToString());
    string httpResponseString = (string)response;
    Console.WriteLine("return status success: " + status.Success.ToString());
    Console.WriteLine("return value: " + httpResponseString);
}
