Question
Can HttpWebResponse be obtained from Html Agility Pack HtmlWeb?
As in, if I call:
HtmlWeb web = new HtmlWeb ();
HtmlDocument document = web.Load ("http://stackoverflow.com/");
Is there a convenient method to retrieve the HttpWebResponse from the web instance to view headers - such as to retrieve header properties like content type?
There are pre and post delegates, which will work:
HtmlWeb web = new HtmlWeb ();
web.PreRequest = delegate (HttpWebRequest request) {
request.Timeout = 10 * 1000;
return true;
};
web.PostResponse = delegate (HttpWebRequest request, HttpWebResponse response) {
//response.Headers;
//response.ContentType;
};
HtmlDocument document = web.Load ("http://stackoverflow.com/");
Instead, is there a way to get the response something like: (HttpWebResponse)web.GetResponse();
Accepted Answer
You can use TaskCompletionSource + async/await
var web = new HtmlAgilityPack.HtmlWeb();
var tcs = new TaskCompletionSource<HttpWebResponse>();
web.PostResponse = delegate(HttpWebRequest request, HttpWebResponse response)
{
tcs.SetResult(response);
};
var document = web.Load("http://stackoverflow.com/");
var httpWebResponse = await tcs.Task;
