.NET: Is it possible to get HttpWebRequest to automatically decompress gzip'd responses?
- by Cheeso
In this answer, I described how I resorted to wrappnig a GZipStream around the response stream in a HttpWebResponse, in order to decompress it.
The relevant code looks like this:
HttpWebRequest hwr = (HttpWebRequest) WebRequest.Create(url);
hwr.CookieContainer =
PersistentCookies.GetCookieContainerForUrl(url);
hwr.Accept = "text/xml, */*";
hwr.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip, deflate");
hwr.Headers.Add(HttpRequestHeader.AcceptLanguage, "en-us");
hwr.UserAgent = "My special app";
hwr.KeepAlive = true;
var resp = (HttpWebResponse) hwr.GetResponse();
using(Stream s = resp.GetResponseStream())
{
Stream s2 = s;
if (resp.ContentEncoding.ToLower().Contains("gzip"))
s2 = new GZipStream(s2, CompressionMode.Decompress);
else if (resp.ContentEncoding.ToLower().Contains("deflate"))
s2 = new DeflateStream(s2, CompressionMode.Decompress);
... use s2 ...
}
Is there a way to get HttpWebResponse to provide a de-compressing stream, automatically? In other words, a way for me to eliminate the following from the above code:
Stream s2 = s;
if (resp.ContentEncoding.ToLower().Contains("gzip"))
s2 = new GZipStream(s2, CompressionMode.Decompress);
else if (resp.ContentEncoding.ToLower().Contains("deflate"))
s2 = new DeflateStream(s2, CompressionMode.Decompress);
Thanks.
